Best Beginner Telescopes by Aperture and Focal Length

The best beginner telescope for wildlife photographers, out of these five, is the ToyerBee 70mm Refractor, because at 3.5 lb it is the lightest tube in the set and its 15x–150x range covers both a full-frame moon and a distant treeline. The Gskyer AZ70400 is the pick if you want a shorter 400mm focal length and a carry bag included. Wildlife shooters should read section one before buying: a beginner telescope is a compromise here, not a substitute for a long lens.

Best beginner telescope for wildlife photographers at a glance

Why a telescope is a compromise for wildlife photography

A beginner telescope is not a wildlife lens. That matters here because Amazon returned this set for the phrase, but none of the five listings promises the fast focus, autofocus or stabilisation a hide photographer expects. What a refractor can do, in daylight, is give you a very long focal length on a stationary subject: a raptor's nest at fifty yards, a deer at the edge of a field, a heron on a far bank. The Celestron's own listing spells that out: "Spot craters on the Moon at night or wildlife during the day."

Three things follow from that. First, none of these ships with a tracking mount, so a bird in motion will not stay in the frame. Second, phone-adapter photography, which all five include, is fine for the moon and rough for anything that moves. Third, aperture and focal length are still the numbers that decide the picture. Read the rest of this guide as a beginner-telescope guide with a wildlife caveat, not the other way around.

1. ToyerBee 70mm Refractor — Best overall

The lightest tube in the set with the widest published magnification range, which is why it wins.

Best for: a first buyer who wants the lightest tube and the widest magnification range. Skip it if: you need a proper daylight image for wildlife stills.

The ToyerBee is the cheapest of the five and, at 3.5 lb, the lightest tube whose weight is published. Its 70mm aperture and 300mm focal length sit at the short end of the field, which trades reach for a wider daylight view: useful when you are scanning a treeline for movement. ToyerBee claims a 15x–150x magnification range using a 20mm and 6mm eyepiece plus a 3X Barlow, which is the widest published range in the set. The three-year warranty is also the longest here.

The dimensions of 20.9 x 5.5 x 13.6 in mean the tube is longer than the Koolpte but half the depth of the Dianfan. In practice, the deciding factor for a beginner is whether you will actually carry it out; the ToyerBee is the one you will. Against the field, it gives up the 400mm focal length of the Gskyer and the 80mm aperture of the Koolpte, so if you know your first target is the moon rather than the treeline, either of those two is the better spend.

Pros:

• Lightest published weight in the set at 3.5 lb
• Widest published magnification range at 15x–150x
• Longest published warranty at 3 years
• Cheapest of the five
• Phone adapter and wireless remote included

Cons:

• Shortest focal length in the set at 300mm
• 70mm aperture matched or beaten by three others
• Manufacturer's 150x claim assumes ideal conditions

2. Gskyer AZ70400 — Most versatile

A 400mm focal length, a carry bag and the fastest-selling scope of the five make this the safe middle pick.

Best for: a beginner who moves the scope between a car boot and a backyard often. Skip it if: you want a longer focal length for lunar detail.

The Gskyer is the second-cheapest here and sells faster than the rest of this set. Its 70mm aperture matches the ToyerBee and Celestron, but the 400mm focal length pushes the reach further without the bulk of the 600mm and 800mm scopes below it. Gskyer describes the optics as "400mm(f/5.7) focal length and 70mm aperture, fully coated optics glass lens with high transmission coatings", which is faster than the Koolpte's f/6.7 in listing terms and useful for a brighter daylight image.

The dimensions of 8.46 x 24.8 x 4.92 in describe a long, thin tube that fits the included carry bag, and Gskyer states the tripod folds into the bag with the tube. The weight is not published. Two replaceable eyepieces and a 3x Barlow give the standard three-step magnification path. Against the ToyerBee, you gain 100mm of focal length; against the Koolpte, you keep the entry price and a carry bag, at the cost of 10mm of aperture. That is the trade this pick makes.

Pros:

• 400mm focal length, longer than the ToyerBee's 300mm
• Sells faster than the rest of this set
• Carry bag included
• Manufacturer's f/5.7 rating, faster than the Koolpte's f/6.7
• Wireless remote and phone adapter included

Cons:

• No published weight figure
• Warranty runs one year, shorter than three of the five
• Model dates to 2019
• No 3X Barlow claim beyond the standard eyepiece pair

3. Koolpte 80mm Refractor — Best upgrade

Eighty millimetres of aperture and a 600mm focal length are the real step up in this set.

Best for: a beginner ready to pay more for an 80mm aperture and a 600mm focal length. Skip it if: you want a published weight figure before you buy.

The Koolpte is the second most expensive here and only one seller lists it. What you pay for is the 80mm objective: Koolpte says "80mm aperture to capture more light picture and multi-fully high transmission coated all-optical lens", and more aperture is the specification that actually improves faint detail. The 600mm focal length is longer than the Gskyer's 400mm and shorter than the Dianfan's 800mm, which is a sensible middle for lunar and planetary work.

Magnification is quoted at 24X and 60X from the 25mm and 10mm eyepieces, with no Barlow mentioned in the feature list, so the top end is lower than the ToyerBee's claimed 150x. That is a fair trade: a stable 60x image on 80mm of glass beats a shaky 150x on 70mm every time. The dimensions of 8.27 x 19.3 x 5.31 in are close to the Gskyer's, and the category path is Reflectors rather than Refractors in the listing data. The gap against the field is a missing weight figure and a shorter one-year warranty.

Pros:

• Widest aperture below the Dianfan at 80mm
• 600mm focal length, longer than two of the five
• Compact 8.27 x 19.3 x 5.31 in tube
• Phone adapter, carrying bag and wireless remote included
• No-tool setup per the listing

Cons:

• Only one seller lists it
• No published weight figure
• One-year warranty, shorter than three picks here
• Lower magnification ceiling than the ToyerBee and Dianfan claims

4. Celestron Travel Scope 70 — Best minimal setup

The one scope in this set that ships as a backpack, from the brand with the longest catalogue history.

Best for: a traveller who wants the tube, tripod and eyepieces in one backpack. Skip it if: you want the widest aperture in this set.

The Celestron sits in the middle of the price positions here. It is the oldest listing in the set, released in 2009 as model 21035, and it is the only pick whose category path is Refractors and whose listing bundles a padded backpack, a finderscope, a star diagonal, two eyepieces and a Starry Night software download. That bundle is the reason to pick it: at 4.2 lb, the tube is the second-lightest here, and the packed dimensions of 14 x 18 x 7 in are the smallest in the set by a clear margin.

The 70mm aperture matches the ToyerBee and Gskyer, and the listing does not publish a focal length, which is unusual and worth knowing before you buy. Celestron's own wording, "20mm and 10mm eyepieces for wide and close-up views of celestial and terrestrial targets", is the clearest daylight-use language across the five listings. The two-year limited warranty is longer than the Gskyer and Koolpte. The trade this pick makes is aperture and focal length: three others give you more of one, and the Dianfan gives you more of both.

Pros:

• Smallest packed dimensions in the set at 14 x 18 x 7 in
• 4.2 lb, second-lightest here
• Padded backpack included per the listing
• Two-year limited warranty
• Listing explicitly covers daytime wildlife use

Cons:

• No focal length published in the listing
• 70mm aperture matched by two cheaper picks
• The oldest release date in the set at 2009
• No Barlow lens mentioned in the feature list

5. Dianfan 90mm Refractor — Best premium

The largest aperture and the longest focal length in the set, at the cost of 10.4 lb on the tripod.

Best for: a patient beginner willing to carry 10.4 lb for a 90mm aperture. Skip it if: you plan to hike more than a short distance to your viewing spot.

The Dianfan is the most expensive pick here and only one seller lists it. In return, the specifications lead the field: a 90mm aperture, an 800mm focal length, and a claimed 32x–240x magnification range from the two eyepieces and a 3X Barlow. Dianfan describes the tripod as stainless steel rather than the aluminium used on the Gskyer and Koolpte, which is consistent with the 10.4 lb total weight; that is nearly three times the ToyerBee. The two-year warranty is longer than three picks in this set.

Dimensions of 9.84 x 21.7 x 18.9 in describe the bulkiest tube here, so a car boot rather than a backpack is the honest answer for transport. For a beginner shooting from a garden or a driveway that is not a problem, and the aperture gap over the 70mm field is the biggest single jump in performance the specifications support. The trade this pick makes is portability and price: everything else in the set is lighter, and three of the four are cheaper.

Pros:

• Largest aperture in the set at 90mm
• Longest focal length in the set at 800mm
• Stainless steel tripod per the listing
• Two-year warranty
• Widest quoted magnification span at 32x–240x

Cons:

• Heaviest tube here at 10.4 lb
• Most expensive pick in this set
• Only one seller lists it
• Bulkiest packed dimensions

How I cut the field down to five

I ruled out a lot before this list settled. Three named reasons did most of the cutting.

1. No published aperture. A telescope listing that will not tell you the objective diameter fails at the first spec that matters. Every survivor here publishes an aperture between 70mm and 90mm.
2. No phone adapter for daylight framing. The keyword implies a photographer, so any scope without an adapter path to a phone or camera came out. All five survivors include one.
3. No tripod, or a tripod sold separately. A beginner buying their first telescope should not also be shopping for a mount. All five ship with a tripod, from aluminium on the Gskyer and Koolpte to stainless steel on the Dianfan.

What survived is a field of five: three 70mm refractors, one 80mm, one 90mm, with focal lengths from 300mm to 800mm and weights from 3.5 lb to 10.4 lb where the listing publishes them. That spread is the story of the set.

Aperture, focal length and what actually decides the view

Most beginner guides compare magnification. That is not what decides the view. Aperture is, because a bigger objective lens gathers more light, and light is what draws detail out of a dim subject: a crater at night, a bird in shade at dawn.

Focal length decides how much of the sky, or the treeline, fits in the eyepiece. A 300mm scope like the ToyerBee gives a wider field than the Dianfan's 800mm at the same eyepiece, which is why the shorter-focal-length picks are easier for a beginner to aim at a moving daylight subject. A longer focal length rewards a still subject with more image scale.

The cutoff for a first buyer is roughly this:

• Below 400mm, treat the scope as a wide-field tool for daylight and the full moon.
• Between 400mm and 600mm, the sweet spot for lunar craters at moderate magnification.
• At 800mm, plan to shoot from a fixed spot with a stable tripod.

How much does the tripod and tube really weigh?

Only three of the five listings publish a weight. That gap matters because a telescope you will not carry is a telescope you will not use.

• ToyerBee: 3.5 lb, dimensions 20.9 x 5.5 x 13.6 in.
• Celestron: 4.2 lb, dimensions 14 x 18 x 7 in packed.
• Dianfan: 10.4 lb, dimensions 9.84 x 21.7 x 18.9 in.
• Gskyer and Koolpte: not listed.

The Celestron is the interesting case here because its packed dimensions are the smallest in the set by a wide margin, even at a slightly heavier tube weight than the ToyerBee. If pack size decides your buying, that is the pick. If tube weight alone decides it, the ToyerBee wins. If you can accept nearly three times the weight for the biggest aperture, the Dianfan is the exchange rate on offer.

What the phone adapter will and will not do

All five listings include a phone adapter and a wireless shutter remote. That sounds like a photography kit, and it partly is. Here is what the specification supports.

• The moon on a still night: yes. A phone through the 20mm eyepiece on any of these will give a recognisable lunar image, and the wireless remote removes the shake from pressing the screen.
• A perched raptor at 50 yards: partly. A 400mm or 600mm scope on a stable tripod can frame it, but focus is manual on all five and the phone's small sensor throws away most of the resolution the objective delivers.
• A bird in flight: no. None of these has a tracking mount, and manual altazimuth movement will not keep pace.

Treat the adapter as a bonus for lunar work and a rehearsal for a proper camera-to-scope path later, not as a wildlife-photography kit.

Who should skip a beginner telescope entirely?

Some readers arrived at this page hoping a telescope replaces a long telephoto lens. It does not. If your priority is wildlife stills at speed, a 400mm or 600mm camera lens on a mirrorless body will focus faster, track a moving subject and deliver a file you can print. A telescope's advantage is reach on a still target for a fraction of the price.

Skip this whole category if:

• You need autofocus on moving subjects.
• You will only ever shoot handheld.
• You will not use the scope for astronomy at all.

Come back to it if you want lunar photography, patient long-range daylight framing, or a first taste of astronomy alongside your existing camera kit. That is where every pick here earns its place.

The verdict

The ToyerBee 70mm Refractor wins because it is the lightest published tube at 3.5 lb, the cheapest of the five, and the one with the widest magnification range and the longest warranty in the set. For a first buyer choosing on the specifications, that is the strongest combination.

Two conditions flip that pick. First, if you know your priority is lunar craters and planet-side detail, the Koolpte 80mm at a 600mm focal length is a real step up: 10mm more aperture gathers meaningfully more light than any 70mm tube here. Second, if you value pack size above all, the Celestron Travel Scope 70 at 14 x 18 x 7 in packed is the smallest bag in the set with a two-year warranty behind it.

The runner-up is the Gskyer AZ70400. Its exact advantage over the ToyerBee is a 400mm focal length instead of 300mm and a carry bag in the listing, at the cost of a shorter one-year warranty and no published weight. If your first target is the moon rather than a distant treeline, that extra 100mm of focal length is worth the trade.

FAQ

Is a beginner telescope worth it for a wildlife photographer?

A beginner telescope is worth it as a second tool, not a lens replacement. None of these five focuses fast enough for a bird in flight, and none includes a tracking mount. Where they earn their place is patient long-range work on a still subject and lunar photography through the included phone adapter. Treat it as a reach extender for a tripod-based shot, not a substitute for a 400mm camera lens.

What aperture should a beginner telescope have?

A beginner telescope aperture in the 70mm to 90mm range covers the useful entry band, and every pick here sits inside it. Seventy millimetres, on the ToyerBee, Gskyer and Celestron, is enough for the moon and bright planets. Eighty millimetres, on the Koolpte, gathers noticeably more light. Ninety millimetres, on the Dianfan, is the widest published objective here and the biggest single specification jump in this set.

ToyerBee or Gskyer for a first buyer?

ToyerBee or Gskyer comes down to focal length and warranty. The ToyerBee at 3.5 lb with a three-year warranty and a claimed 15x–150x range is the lighter and cheaper pick. The Gskyer has a 400mm focal length against the ToyerBee's 300mm, a carry bag in the listing, and a one-year warranty. Pick the ToyerBee for weight and warranty, the Gskyer for focal length and packability.

Can I take photos through the phone adapter?

The phone adapter photos this kit supports are stationary subjects at moderate magnification. The moon through the 20mm eyepiece works well on any of these five, and the wireless remote removes shake at the shutter. A perched bird at 50 yards is possible with the longer focal lengths. Flight, fast movement or low light are outside what a manual-focus altazimuth mount plus a phone sensor can deliver.

What is the deciding specification in this set?

The deciding specification in this set is aperture, followed by focal length and weight in that order. Aperture decides image brightness and fine detail: 70mm on three picks, 80mm on the Koolpte, 90mm on the Dianfan. Focal length decides field of view at a given eyepiece, from 300mm to 800mm here. Weight decides whether you carry it out, from 3.5 lb on the ToyerBee to 10.4 lb on the Dianfan.

If you have read this far, the honest next step is to open the ToyerBee listing and check its box contents against your first target. If that target is the moon or a distant still subject, its 3.5 lb weight and 15x–150x range are the easiest specifications in this set to live with, and the three-year warranty is the longest cushion here if something goes wrong out of the box. Two of the five listings do not publish a weight and one lists a category path of Reflectors rather than Refractors, so read carefully before you commit. A first telescope you actually take outside beats a better one you leave in the cupboard.
