Continuing to test the wonderful Askar SQA 85 mm f/4.8.
Galaxy M 106 was first discovered by Pierre Méchain on July 30, 1781, in the constellation Canes Venatici.
The distance to the galaxy is about 24 million light years.
Diameter 135,000 light years.
Angular size 18.6'x7.2'.
Доработана в Pixlnsignt астрофотографом Антоном (пользователь Anth https://www.deepskyhosting.com/id1059), за что ему большое спасибо.
Где бы её взять эту чудо программу?
Однозначно Pixinsight...
Продолжаю тестировать замечательный Askar SQA 85 мм f/4.8.
Галактика М 106 впервые обнаружена Пьером Мешен 30 июля 1781 года в созвездии Гончих Псов.

Alexey, hello.
I also just got my first frames with this telescope.
Can you tell me what FWHM you get on single frames with the 2600 and the 183 camera?
My name is Anton, nice to meet you )
FWHM is roughly a measure of star size in an image.
If you use the ASTAP program, you can select a specific file, choose the menu item Tools->Image Inspection, and then press F4.
First, you'll see a polygon showing the curvature across the field, and you can immediately tell if there is tilt in the sensor or not.
And second, the star sizes across the entire frame are visible.
Here you go, it wouldn't fit in an email—two sets of raw files from two different cameras, everything is labeled.
And please let me know what you think about the telescope, your opinion.
I made my own version of processing your original data for M106, please take a look.

I also really like the telescope—great resolution, and color is easy to extract from the raw data.
I do notice a bit of spherical aberration in the stars—they look a little fluffy; I’d prefer a bit less of that effect.
But you can always find a flaw in any telescope; this is more about wanting to achieve that unattainable perfect quality.
Thanks, Anton! The processing is superb, I can't do it like that. Can I post it if you don't mind? I also need to switch to PixInsight, but I don't have the opportunity right now. Also, your photos aren't showing up in the feed—check your settings on deepskyhosting. I'm liking them, but they don't appear in the feed. Thanks again and clear skies. Always happy to chat with you!
Thanks, Anton! The Triplet is processed beyond all praise, I'll definitely be in Adygea, and I'll absolutely finish capturing the Snail! In general, stay in touch, clear skies!!

Sorry, I don't know the name.
I can tell you where to look for this parameter, but otherwise, I'm ashamed to admit I don't know what it is.

Always here for you :)
Of course, post it—no question about it.
I’ll send you the Triplet a bit later too.
Here's your triplet: https://disk.yandex.ru/i/WqYFexVNh2YNsA
The detail is at the level of larger instruments.
