I got a new setup ready and only a short opportunity for first tests, but still managed to find out I need a smaller counterweight ToupTek ATR3-16000 is a color cooled camera with same Panasonic sensor as ASI1600 (RisingCam on Aliexpress, also branded by ES, Astroshop and others). Crop, 10s x 200; Baader Neodymium Moon & SkyGlow: Imaging setup (- helical focuser): To have more fine focus on the RedCat 51 I used a very short non-rotating T2-T2 helical focuser from Teleskop Express.

I got few astrophotography related books and checked what they offer and how modern they are. Books in question are: OpenSource Astrophotography 2.2: Your first low cost astro photo from your backyard; Karl Sarnow Scientific Astrophotography: How Amateurs Can Generate and Use Professional Imaging Data; Gerald R. Hubbell The Astrophotography Manual: A Practical and Scientific Approach to Deep Sky Imaging; Chris Woodhouse Astrophotography; Thierry Legault Review: https://rk.edu.pl/en/quick-review-few-recent-astrophotography-books/

Dedicated planetary telescopes aren't produced on such scales as your average fast Newtonian so the price gets higher. Add a low volume high quality small company and the price goes even high. f/12 is still good although the aperture could be bit bigger. f/20 can be problematic as planetary cameras get smaller and smaller pixels. There are some Sony big pixel sensors, but those are only in PGR cameras at the moment.

It's only a planetary/lunar camera. For that price I would consider ASI034 or QHY5R-II cameras - as those are proven and what's more important - supported by good capture applications - FireCapture / SharpCap. Those cameras will however require a USB connection with a laptop (or some Windows tablets). And don't expect to much. Pretty astrophotography is quite expensive and takes "a lot" of processing time to get the final image. Buy after you check what can be achieved with given hardware.

For some reason I never had "stability issues" with Ubuntu releases. And I don't like using old software for pseudo-stability.

I works since long time, but still it's better to have the latest Ubuntu release for the latest software.

I work daily on Linux, but for astrophotography I use Windows. The Linux alternative are either insufficient or none. Some Windows apps work through Wine, but still I want a stable platform as much as possible and best applications I want to use.

You need c-mount to T2 thread adapter and then it will look similar like the DSLR. I wouldn't use such camera for general DS imaging.

You will get higher resolution and much smaller FOV. Chech the FOV calculator if it's ok for you and if the resolution is not to high (seeing limit etc.)

It's a CMOS, not a CCD, similar to that in ASI120/QHY5L-II. The difference between DSLR is that this sensor is very small (1/3") and has very small pixels so it will perform "good" only in short focal length and very fast telescopes (not common). The mono version for Solar System imaging is much better.

Looking at the application screen shots they ought to add exposure time as a slider too for planetary imaging, as it's quite handy too. Some FireCapture ideas like storing camera settings per filter are also nice to see in other apps. (and I'm not a fan of multiple "floating windows", one is better for me).

It can't do both things at the same time

French Solar System cameras, rather popular there, but the latest cooled version brings the prices close to typical DS cameras. If you want a all-in-one (planetary/lunar/DS) then some models could be interesting. Similar idea will be used in QHY miniCam5s (but you still would need a guider for DS imaging ) Cooled iNovas look like so: http://www.pierro-astro.com/materiel-astronomique/cameras-astro/cameras-inova-serie-nebula_detail

If the HDD isn't fast enough (or busy with other I/O operations) then the frames lag behind cached in RAM.

Depends on camera and object. Either so aperture is the king.
