Nice job, Sarah. You continue to get better.

Sarah, Thanks very much. I just used your super tutorials to process M33 and M13 for the 2024 Starfest Imaging Salon Contest. I could not have done it without your detailed, expert instructions.🤩

Why did you not image the same objects (M 31) with the 2 refractors, so we could compare. So annoying.

Finally got around to watching this... Really good in-depth review of both piecea of equipment...!!! Enjoyed the interview at the end and thought the question regarding smart telescopes for Aurora was quite interesting... I could see an interesting space (pun intended) there where you could set up a smart telescope where once it detected a change in color/movement, it would start recording... Might make capturing those spontaneous auroras more frequent... Maybe tie it into an online database in real time that measure the KP-index, Bz, and other attributes that can help as well... Definitely interesting... I caught some great shots of the Aurora this past January when I was in Rovaniemi, Finland... Amazing experience... Do you think there will inevitably be an integration of smart telescopes with AI...? As always, another great video... Keep it up...!!!

Please more please about cosmos and astronomy. Add. Like all about space and Universe. All subscriptions about Space 😮

The best and most thorough review - much appreciated! The striations on the bright star hopefully will be resolved by the manufacturer - if they are from the reducer optics(?) or the main OTA or a combination of both. Hopefully too, you get to do more of these excellent in depth reviews! Thanks!

excelent excelent excelent ... thank you

I guess if I want great Astro pictures I need to move from Florida to a state like Kansas right ? Well I'm starting today a 2 weeks trip all the way to Canada, I hope I'll get nice results, I have all the equipment I can dream of but I have no experience (beside the moon and the sun) in astrophotography.

Very in-depth, thank you.

Excellent !! thank you thank you

It's so detailed, comprehensive, and professional! Thank you for that great video!

Great Content, as usual!!! ❤❤

A smart, very attractive woman with glasses. Im not interested in this product but i watched it for her.

Super helpful. Thanks!

Hello. I have also used telescope eyepieces that have a thread near the viewing lens, this thread allows attaching to an adapter tube that attaches to the camera. It makes the eyepiece centrally align with the cameras sensor and so removes any annoying light path offset or wobble. I have also used something similar to allow people who have Fixed-lenses cameras to screw their complete camera+lens units onto the eyepiece adapter and attach to the telescope, they took some moon photos and were very happy.

Thanks!

A very thorough and well presented test, thank you! Yours and Nico’s are among the best scope reviews on UA-cam. Here are some tips from me, gleaned from many years of testing optics, that you might find useful. I can say that the most sensitive method of checking for pinched optics, astigmatism, or spherical aberration is to perform a high-power star test visually. The bible for how to test optics is the book by Richard Suiter, sold now by Sky & Telescope. If a bright star image looks elongated or triangular and flips orientation as you rack thru focus, you’ve got either mechanically pinched optics (mounted badly) or astigmatic optics (made badly). Backing off the tightness of any ring holding down the front element, if that can be done, might fix pinching. Pinching can also get worse in cold weather as metal in a lens cell contracts and stresses the glass. However, I doubt you’d see the effect of pinched optics on such a bright overexposed star image. The dark radial artifacts you saw are more likely from some form of diffraction from the mechanical components in the lens cells of the flatteners. Not pinching per se. The fact they appeared in a different position with each of the three flatteners suggests the effect was from their optics, not the main scope. Assuming the images were all oriented the same way. But a visual star test would easily reveal if the main optics were indeed at fault, either pinched or astigmatic. Best to confirm that before accusing a scope of having a flaw many might deem fatal! I’ve tested several Askar scopes, including the APO120 for Sky & Telescope magazine with a unit sent to me about the same time they sent your 103. I’ve yet to see any Askar refractor with pinched or astigmatic main optics. Not to say it’s not possible. But, if you suspect pinched optics, a visual star test will show that, revealing on-axis aberrations or flaws in the main optics down at the 1/8 to 1/4-wave level that photos may never show. On the other hand, images reveal field flatness and off-axis aberrations. But … images involve the flatteners, so you can’t be sure what you’re seeing is from them or the main optics. That’s why it’s good to test optics both visually and photographically. If a scope can be used visually, it should be tested that way as well. Even if the main purpose is to shoot through it. I think I’ve made the same suggestion to Nico as well. Learn to look through scopes and star test! Clear skies and all the best!

Tanks!

The Dwarf 3 is taking pre-orders now for delivery sometime later this summer. Do you think it would be a good idea to wait and buy it than purchasing the Dwarf 2?

I've been taking a lot of pictures of the moon for the past few years. And you brought a lot of things to my attention in this video that I didn't factor in. But as odd as this may sound some of the best pictures I've gotten of the Moon we're with a Kodak pixpro az652. I do own Canon cameras but I found it much easier to photograph with my Kodak

Will Blur Exterminator clean up the fringing on the bright stars caused by the pinched optics?

This video was great. So helpful. Thank you.

Seestar doesn’t come with a white light filter for solar it is a Silver Black polymer solar filter

Little Dwarf 😂🎉 Maybe there will be one at the Next Solar Eclipse.

Look at the night sky on a clear night using infrared googles/ scope and you'll see stuff that will blow your mind ..

Glad to see you and Nico hitting it off!

There is one star we can look at without any eye protection, it's you ! :o)

By the way have you done similar step by step on the SeaStar 50?

I just wanted to tell you that when you first released this I listened. I listened again today after ordering my first telescope, an Askar V. I also bought an AM5/ASIair 2 months ago (listened to these reviews too). I had some problems and ZWO's support is awful. Fortunately Woodland Hills, the retailer, was a big help and after 1 1/2 months we finally figured out the problems and I am getting 8 minute exposures with round stars (YA). Thanks for your work. I wish I understand 20% of what you know and I am learning.

you are by far have covered smart telescopes thoroughly than anyone else I know-kudos to you for that. Now Nico is in picture so that just makes it really interesting. Good collab there. Hope you guys do Texas star party video-very interested in that one.

Great video. I enjoyed this a lot.

Thanks for sharing. Your presentation skills are outstanding! I’m looking forward to SS50 v2. In interim considering using AI to control existing model using Kai’s work. Major interest to create ‘smart’ scheduling considering weather, moon, location (with location specific obstructions like tree’s), maximum available viewing times, objects of interest). Item 2 is ‘automated’ mosaics. Terry Grey Highland Skies Observatory.

Comprehensive and detailed. That was a lot of work on your part, Sarah. Thank you.

Which one is good among celestron CPC 1100 or celestron Edge HD 11

This was fun and educational. Me, just laying in the bed of my truck on a clear dark night watching the sky is so amazing. 💫 Thanks Sarah.

I'm a little confused. Do we need to do ImageIntegration before DrizzleIntegration?

As always, a great presentation.

Got a Vespera this spring and, I have to say, it is really fun. Never imagined that astrophotography would be for me, but the scope is a good gateway to it. To my undiscerning palette, it seems to be capable enough to get some good shots and learn some stuff. It is not going to be my last stop on the journey, but it fills in a nice spot while I put together and learn to use a more sophisticated setup.

Hi Sarah, your demos are always sound thanks. what will be the best time to shoot sun & sun set?

super rad! i love your videos!

Great video! You do a really good job explaining things.

Sarah - Your scientific knowledge matches your photography knowledge - both are deep! Did you come to astrophotography as a hobby or as part of your education? What is your education and professional background?

Awesome vid, Sarah!!

Is it not our Star named "Sun"? ie "this is Sun" or this is Jupiter .... don't get it.

Wow 26k subs very nicely done

What is this sun you speak of?

Excellent work Sarah. Thanks for doing this video. It will help many people!

happy to see your video... i dig your examples and explanations and such...

A great tutorial - especially with certain aspects of the ISS Transit Finder which I was previously unaware of! I like the interview format too - hopefully you can do more!
