5:09 any idea why there are those extensions in the frame?

Hi Bogdan. I enjoy your videos, thank you. I've been using binoculars and telescopes for decades and prefer porro prisms over roof prisms. Roof prisms seem to be a bit more sensitive to vibration than porro prisms. Also in general roof prisms seem to have a slightly smaller field of view.

Outstanding review! I really appreciated the deep dive into actual performance and the images through them. Thank you!

How dose the 32mm Swan compare to the 31mm Hyperion? Which one is a higher quality lens in your opinion?

I got a Criterion RV 6 about 45 years ago, my first. My second is a Meade RCX 10 I’ve purchased yesterday on a popular sellers site. I’m looking forward to sharing my new hobby with my children. Cheers from Canada

Great shirt dude

The 30 seconds of music in the intro is critical to your channel's success. I suggest keeping it.

Bogdan if you would have to choose for visual observations only (not astrophotography) between the SW Evostar 90/900 mm achromat and the Svbony 80 ED, which one would you pick ? Which one do you think has overall a better optical performance ?

Use a proper camera mate this format is shit to watch

Very nice. I'm just starting out as well. I have the askar 103 apo, heq5, asi 533, 120 guide scope. And having a lot of fun with it. I am having trouble with the processing part, though.

I definitely enjoyed the video and also the imaging session. Next time, we will take pictures from your backyard 👍👍

Great video and great capture! I've got the same mount with OnStep as well. What improved my guiding was using a guide scope and an SV305 Pro guide camera. Now, I can easily get 300-second (5-minute) exposures.

I can see M81 even with a small 70/700 mm achromat from a bortel 6 city. Its one of the brightest galaxies on the night sky.

And nice landscape view!))

The typical off the shelf newtonian reflector in the F/6 to F/4 have a central obstruction of between 20 and 25% of the primary mirror area, as opposed to SCT's which range from 30% to 40%. Newtonians are often significantly better in central obstruction than an equivalent sized SCT, even fast newtonians at f/3.45 to f/2.8 enjoy a central obstruction smaller than some SCT's.

Thanks, Damion. I need near-zenith views, you helped me a lot.

👍👍👍

Please I dont want an ocular with big text "China" on it just stupid it would be another thing if it stood "Japan" on it

you mispoke. Red dot and telrads do not use a laser. They have a low power LED. Otherwide, your description and suggestions are excellent.

SLOW, fast, I need to review about all of it after, as few years off and a lot more money..

Humans have always been interested in observing the sky and invented the telescope for this purpose, whether the telescopes are installed on satellites or the telescopes that are fixed on the ground. Thank you for your good information.

Can such a set be installed in the Bresser EQ-MON2?

Hi what about the TeleVue Ethos, ES 100° and the ES 9mm 120° eypieces. Also the Takahashi TOE for planets. Could you please mention these ultra premium eyepieces as well on you next review. Thank you

Thank you your for your review. I find there is a disturbing push by telescope manufactures for astrophotography using very small telescopes. I personally I cannot see why one would want to go down that path as there is a plethora of photos already on the web far better than I could do even if I had an unlimited budget. The beauty is seeing the object in the dark skies though the telescope eyepiece is something that a photo just cannot produce and this can only happen with a light bucket, having enough light to produce some color in the objects. From my experience unless they just wanting to view the most prominent planets, anything under 10 inch is going to be most disappointing for most people and 10 inch is just marginal as nebulae are just starting to show their beauty. It is a pity that you didn’t review some of the larger scopes and describe the pleasing views one can get compared t to a 100mm refactor.

Thanks for your thorough review of the Askar 71F. I have purchased one and was very surprised with it's overall performance and the quality of the pictures I have taken with it. I currently have on order the 0.75 Reducer that will widen the field of view so am looking forward to seeing how that further affects the performance and quality of the images.

Bogdan now that you have the Svbony 102 ED, do you still use the Skywatcher Evostar 90/900 mm achromat ? Will you keep the Evostar 90/900 mm ? How big would you say is difference in optical quality and performance between the Svbony 102 ED and the Evostar 90/900 mm achromat? Thank you!

Appreciate the video. Can review mounts with a focus on mounts that would be good for both visual and astrophotography? Maybe do multiple price points.

Thanks man i don't really comment on videos but this one really helped me understand filters way more than some threads i've read online!

I'm 65 and had never heard the term, "collimate" until today. Someone gave me a Criterion RV6 that had been sitting in a storage shed behind their home for a couple of decades. I'm sort of new to this so I need to do a lot of catching up. This video helped tremendously and I just ordered my first telescope collimator! Thank you very much. :)

I have got this eyepiece, but one thing you have not mentioned is extremely short back focus this eyepiece needs to focus at infinity, in some of my scopes it can not focus at all (I have two pieces for binoviewer and both work the same, so it is by design). Another issue for those who plan to use it for solar observing is the eye cup design. It is not really blocking light coming from the back causing the image to have very annoying artifacts and lack of contrast. For daylight usage there is a need for additional shield to block side light. Apart from that I consider this eyepiece worth the money.

Hi Bogdan, first of all, thank you for a great content you provide. You always say you're mostly a visual observer. I'm wondering what are your main targets for visual observation? To me it seems if you don't go the astrophotography route you end up having planets, maybe some nebulas and double stars... and that seems to be it?

Thanks Bogdan . . . . You have entered legendary status!

The 82° line from Stellarvue is, in my opinion, excellent and cost 100 dollars per eyepiece. I'm not sure if you've ever reviewed them but I imagine you would like them

Because Orion is sadly out of business in 2024, I’m assuming that’s why my StarBlast didn’t make the list. 🤣

Bună ziua, am cumpărat un telescop Bresser Refractor 2 Goto 127 /1200 și are un ocular de 26 mm plossl . Am probat ieri prima dată, se vede foarte frumos și clar ,am putut observa Jupiter, dar nu sa putut vedea mai mare și mai clar . Poate mă ajutați dumnevoastră cu o sugestie și îmi scrieți ce fel de oculare să cumpăr să observ mult mai aproape planetele și galaxiile. Vă mulțumim frumos!

Thank you, helped immensely

Vidéo intéressante comme toujours avec des sous titres en français vue de la Normandie. Très divertissant et instructif, c'est vraiment un plaisir de vous suivre. Merci.

Fyi...Buck is an informal reference to $1 that may trace its origins to the American colonial period when deerskins (buckskins) were commonly traded for goods. So it's more of a slang word.

Gonna need a cloud removal guide my friend. :/

Great video Bogdan, do you know if the sv503 102mm can achieve focus with the APM 30 UFF? I heard it can't achieve focus with some 2" eyepieces. Thanks again.

BRESSER Messier 12" Dobson Telescope a large 305 mm parabolic primary mirror, 2.5" HEX focuser and very lightweight telescope tube ?

Thanks Bogdan, great recommendations! I have the sv503 102ED which is awesome and a good C5 that holds its own against the sv503. I agree with your top picks too though the $2000 category is a hard call. The C9.25 is a bit of a do it all scope by being relatively portable in spite of its fairly big aperture. I have a 16” dob and globular clusters are just amazing in it!

Insanely expensive

How you keep your hands steady like that

Most of the stars were egg shaped right to the center of the image. They weren't round as you have pointed out. That may be something to do with the mount's guiding or flexture and not the optics though.

A non-sponsored plug for the SvBony 102mm. Awesome scope. Great optics and build quality. I replaced my 40 yo Meade 8" SCT with it. Missing the long FL a little, but so much smaller, easier to use, and more suited for wide field photography. Just my 2 cents...

I did purchase an Askar 120 APO a couple months ago. I mounted it on a ZWO AM5N. Sadly, I haven't' yet taken it out because of getting all the associated accessories collected and mounted. As of today, I now have all of them but it's completely overcast and probably will be until, maybe, Sunday. Fingers crossed.

Hello Bogdan, for around 250 euro, between the Skywatcher Evostar 90/900 mm and a 130/650 mm dobsonian, which one has a better optical performance and overall image quality through the eyepiece (not astrophotography) on the Moon, planets and DSO ? Thank you!
