While there are optically-superior modern eyepieces, such that you could buy several dedicated high-end optics at several hundred dollars each, this is reasonably priced, and a nice compromise.Maybe next year, I'll purchase a 6 mm mercedes equivalent.

Really nice especially for the price but a much smaller difference on the telescope than we expected.

I purchased the Mark IV Zoom and the 17.5 Morpheus at the same time along with an Orion Barlow 2x. I was very pleased with all 3, I bring up the others to compare the differences in types of eyepieces. The “picture†clarity of the 17.5 fixed lens is very high, the Zoom’s is as well but not quite as crisp as the Morpheus. It seems the the eye relief of the zoom is a bit tougher than the fixed lens which is to be expected. Overall I really enjoyed the Zoom and think it’s a great tool to have in the cart for a late night under the stars. The ability to pair it with a Barlow also makes it much easier to “scan†for star systems. I’ve added a modest photo of Jupiter and a couple of its moons that I took with an iPhone 11 and the MarkIV Zoom. Cheers.

I've had this for a few months now and so glad I got away from fixed eyepieces. Sure, you lose out on fov but you more than make up for it with how much more you can focus on the sky rather than fiddling around with eyepieces. Pair this with a 32mm eyepiece and you've got a massive range of magnifications covered.This zoom barlows well, too. You most likely won't need a barlow unless you're lucky enough to have consistently good viewing conditions. I did compare this to other zooms. It was an easy decision sticking with the Baader.

I've been doing astronomy for about 10 years, and the Baader 8 to 24 mm zoom lens is my go-to lens. Agena Astro is a premier supplier of astronomical gear.

in any eyepiece I own. Detailed, crisp, and even better with Barlow. Worth the $$ if you are into astronomy.

This Baader Zoom seems to be well built and has many nice features that I like.So far I have not had the chance to use it on my Telescope do to cloudy and smokeyatmosphere here in the west. I can hardly wait to try it out.

Oculare ben costruito e dalle prestazioni eccellenti. L'ho acquistato per sostituire lo zoom originale di un cannocchiale per osservazioni naturalistiche Celestron Regal M2 80HD che era assolutamente scarso. Bene, il cannocchiale (che possiede un'obiettivo di ottima qualità ) è letteralmente rinato. Immagini nitide, senza riflessi e aberrazioni fino agli ingrandimenti più alti. La dimostrazione che tutti gli elementi del cammino ottico devono possedere la stessa qualità per ottenere immagini perfette. Assolutamente da consigliare, anche per utilizzi con telescopi astronomici!

I bought this to upgrade my Celestron Ultima 80 scope. Read about the Mark III which had mainly positive reviews. The Mark IV greatly improves the Celestron scope over the original eyepiece. The images are clearer by far. I use it mainly for birdwatching and it has enhanced my experience. Colours are much crisper. More detail can be picked out at both lower and higher magnifications. I would say this eyepiece has transformed the Celestron scope into one which I doubt I would have to upgrade unless I was going to go for one of the high end scopes at £1500 plus. It makes the Celestron better than other mid price scopes I have used. Fit is easily achieved and adapters come with the eyepiece. Well worth the money. One tip...find the English language descriptive manual online before you order as only the German version came with my order.

Ottimo prodotto, come da descrizione e recensioni precedenti alla mia. Rispettati i tempi di consegna, imballaggio accurato.Lo zoom Baader fa egregiamente il suo dovere, tra l’altro è recensito più che positivamente in tantissimi forum e siti dedicati, quindi sono andato abbastanza a colpo sicuro in merito alla qualità del prodotto.
