That vignetting is because the camera uses 48mm threads, they need to use a wider interface it probably has nothing to do with the scope, but it would probably be less pronounced on a slower scope

Comments on the SvBONY 48p which I just bought for like $230. It did not come in a case. It has a shoe for a finder. The rings are not removable, I suppose you could loosen them and rotate the tube around a bit . The focuser is a little sloppy but there are 4 hex screws you can tighten it with and fix that. It can use 1 1/4 and 2 inch eyepieces. The focuser can be rotated.

Great video, thanks!! One comment on the gear section: biggest, fastest scope. Really what you want is just aperture. That defines the number of photons you catch from the target object. A faster scope, and hence your focal reducer, shows more sky with more total photons and so is brighter, but for your target, that means it squeezes those photons onto fewer pixels. So, yes, those pixels are brighter, but the image is smaller, working against your desire for a small-pixel camera. The scope F/# gives you nothing useful here, because you are only interested in the image of a particular object. The way you get more photons is aperture and/or time.

Who would have thought that "Askar" don't make any reflectors? Surprise, surprise.

I just started with astrology photography and I'm the 'Keep it simply' 😅

Please tell me the visual Strehl ratio of the Asker 185 APO. By the way, Takahashi's large aperture refracting telescopes TOA-130N and 150B are completely aberration-free. And the imaging performance of the TSA-120 is close to them.

Hi Nico! Did you have a chance to test filter Altair SkyTech L-PRO MAX, which seems is analog of Optolong L-Pro?

Hello, very interesting video! Did you had chance to test filter SkyTech L-PRO MAX, which seems is analog of Optolong L-Pro?

It uses cheap glass.

Those scopes would be a piggyback finder scope for my, 9.25 sct . Hand work speaking is overload for me. Rock on 🤘

Thanks for the demo nice can i click sunset instead of sun?

Great information on the lenses tested. Do have any recommendations for Nikon Z 9 camera 16mm or 20mm 1.8 range?

A portable battery like a Jackery (or other brand) is just as affordable as a lead acid battery. It also has the benefit of not needing an external charging system, and it is far more flexible with the types of power it delivers (110v, 12v, USB, etc). I would 100% recommend that over a lead acid battery.

Doesn't the spin of the earth mean you need to keep on moving your camera so you stay focused on the right part of the sky?

Hello, my name is Mateusz, I am from Poland. Please turn on the Polish language regarding text options. on your YT channel Older videos had this option, but new videos don't have this option. Regards, you are doing a great job.

I've watched this review last year out of curiosity but came back to it just no as only now I'm in a position to purchase a new mount. The issue not mentioned here is DEC axis balancing still required for all HEM-type mounts (it's a traditional GEM axis after all). This could've influenced slower DEC recovery with lighter load while heavier load might have had a chance to be better balanced, bringing HEM closer to AM5. Just a thought. Great review otherwise!

In professional astronomy land, ROI imaging is a well known technique for jacking up your frame rate. Having used it myself for high-speed photometry, I'm not aware of any downsides. It works well!

Great video. You mentioned the use of an IR cut filter that passes H alpha. Are you using a Kolari Vision filter? Which one did you use? Thank you and have a nice day.

Thanks for this video, successfully got Starnett added to Siril via your instructions!

Hey there Nico - thanks for the video - have you tried a tool called astrohopper? Just wondering what you thought of it compared to the procedure you describe in this video.

Good 👍

This is excellent and will help me quite a bit. Thank you!

A weird request :) I am going toward the DSLR path with DSLR lenses… I was wondering if you could create playlist with your historical video that fits this path…

Finding different galaxies and looking up to them using your telescope depends on what telescope you need to use see and find them and what angle you should look at it depending what galaxy or nebula you wanna find also depends on the light pollution of the sky. Light pollution are usually caused by very bright lights at night time if you wanna see some other galaxies or even nebulas you’ll have to move away from the city lights.

you are the one using them, sure would be nice to get more of a comparison summary

Hi! how come you do not use the astrophotography dedicated Pentax k1 (ii)?

Why did you add background noise to the audio? Do you think that makes the audio better?

Very nice thanks The first statement for me is important… “you don’t need a telescope “

Connection by cable are very archaic… These days you need: WiFi and USB-C Assuming speed equivalent to usb3 min

Woah nice!

I'm surprised that you choose a zoom photography camera lens. A 300 f/2.8 would be a better corrected lens and probably better for astro. It would also have fewer elements, and probably a better T value. I love these reviews and am thinking of trying some astro with my 500 f/4 lens. Thanks for including a photography lens in this shoot out!

Hey do you think I could do this on 35mm film? I would be very interested if you have any advice.

with digital cameras its no longer about needing light buckets, thats why refractors are getting so popular with deep sky stuff, so aperture should be considered more about resolution than light gathering...as long as optics quality is good enough you are close to diffraction limited

Hey Nico, I ran into a question that has me baffled. So I took out my Apertura 60mm F6 telescope on my SA2i the other night, mainly to test it out. I also have the Field flattener and also another .8x reducer/flattener. First, it took forever to get focus. But the issue I had was that even with the flattener on there, the stars all the way around the edges looked WORSE than when i used my 75-300mm kit lens. I am connecting the T3i to the telescope via 1.25 T-Adapter... I thought that when I unscrewed to the 1.25 tube, that I would be able to screw the camera on directly, but apparently I dont have the right size. Any thoughts on why the stars are so bad while using a flattener?

With Pixinsight now priced at $329 it should take -2 points instead 0. For a person that makes money with AP and has thousands of dollars, $329 worth the price. But for most starting hobbyist the price is an outrageous. PI team should have a lite of version of the app with the most useful basic tools. Oh well...Siril, Graxpert and Gimp is the way to go combo at no cost.

A word of advice, the Apple App store doesnt have (or at least discernibly) the Discord app, I searched app server and discord everything and got a bunch of nothing... Let Google guide the way to the mothership

Does the DIYer shot have a sharp horizon/nearby objects because it was only a 30 minute shot in total? Or did you have to edit that in post?

Thank you Nico I learned a lot!

What star guiding mount do you recommend for doing astrophotography with the ttartisans 500mm??

Amazing! Is it also possible to take pictures with this set of NGC 1499 or M81?

Nico, on the Star Adventurer GTI mount I found if you spread the weights with a couple of inches between them balance can normally be achieved。 I did not have a camera setup but did have the SVbony 60mm guidescope attachedand was able to balance the rig.

great video, as usual! I have a question: how much sense has to buy a 400mm telescope (doublet) if I have a 400mm prime lens?

Great short Nico ,alway enjoy your stuff ,keep up the great work

Very nice review and results. Now I can't wait to get my 140APO that is enroute.

WOW!!!! I’m so excited to try this tonight!! Ty!!!!!

At the 37:55 mark of the video, did anyone else hear what sounded like a child or a baby? Right after the moment when Jason was mentioning the cemetery

I know everyone's here for AP, but when I see a 6" - 7" refractor something in me yearns for a diagonal & eyepiece....

Definitely cool video. I’d be more interested in seeing the difference between a comparable COST astrocam and modified mirrorless. I don’t think many beginners would be comparing something with such a large price difference.
