Any Benefit to Adding an External Cooler to Mirrorless Camera?

Any Benefit to Adding an External Cooler to Mirrorless Camera?

I'm doing long exposure terrestrial photography, not astrophotography. But I figure you folks would know best about such things. I have a Nikon Zf. And I'm wondering if there would be any noticeable noise-reduction benefit to adding a cooler? Example: Ulanzi CU01

I want to do exposures ranging from a few minutes to a half hour.

How the heck do I mount my Sony A7R V onto the Star Adventurer GTI?!

I’ve bought a ton of different things trying to get to work and still nothing. What I currently have now is:

-SV219 Telescope Dovetail Plate
-NEEWER QB-NA
-SmallRig L-bracket
-Sirui KS-20 ball head

Nothing works!! The NEEWER doesn’t fit on the dovetail. Neither does my camera.

Am I missing something??!

My first M31: beginner questions (capture and processing)

Hi everyone,

First of all, thank you to everyone who helped me on last week’s post about my very first polar alignment: it worked! I managed to shoot Andromeda and stack the frames. It’s very rudimentary, but I’m really happy: it’s my first deep-sky photo, and watching a galaxy appear is something else.

Gear: Sony A7III + Svbony SV555 APO (243 mm, f/4.5) on a Star Adventurer GTi. 58 × 30 s at ISO 800 (about 29 min total), stacked in Siril. No darks, flats or bias for this first one.

(photo here : https://ibb.co/7NK0gtB6)

I now have lots of questions:

Capture

  1. After my 2-star alignment, I set up the rest of my gear (intervalometer, dew heater). I don’t do it before because the cables tangle when the mount moves, and it also affects my manual focus. The problem is that the camera and lens (on the dovetail bar) are touchy and shift easily when I handle things, it’s almost impossible not to. Does that matter? When I recenter the second alignment star, it’s fine, I manage easily. But sometimes I have to do this setup after choosing my target (here Andromeda), so after the alignment: could touching the gear mess up the alignment? Do you have a solution? Should I fully tighten the clamp that holds the dovetail bar on the mount (even though it then can’t pivot at all)? Am I doing something wrong?
  2. To recenter my first alignment star, I sometimes move the mount directly using the angle adjustments rather than SynScan, because it’s faster. Is there any risk for the motors?

Darks, flats, bias

  1. I understand darks. For flats, I was told to use a white screen (my phone) in front of the lens, with a white T-shirt over it. My problem: I can’t see myself holding my phone over the lens for ten minutes to get my frames. How do you actually do it in practice? And about the white T-shirt: if I do this during my night session, it will look black. How does it work in that case, does it still work?

Processing

  1. I processed my photo in Siril (with an AI helping me through the steps). Which processing software do you use and like? Is Siril enough, or is there something better to bring out more detail? I have a Mac and a Windows PC.
  2. I’m a photographer otherwise and use Lightroom. How does astro post-processing work: should I use it in Lightroom like a regular photo (exposure, contrast, etc.), or is it a completely different job?

Thanks in advance, and clear skies!

Where do you order astrophotography prints?

I've been researching where to order astrophotography prints. I'm struggling to find a business that accepts high file sizes at a reasonable price. Any suggestions?

New equipment opinions?

Hey all. Currently imaging via the zwo ecosystem, asiair plus and 2600 colour. Looking to change to open source controller and mono camera.

Any opinions on the Astro PC Pro 2 controller?

Camera wise, looking pretty firmly at the Player One Poseidon M Pro, and Scorpio LRGB/SHO filter sets.

Would appreciate any feedback, open to being convinced otherwise.

Tyvm for any help.

Minimum focal length to render smaller galaxy detail?

After imaging the supernova in NGC 7331 the other night it became painfully obvious my optic's focal length is pushing the limits of what detail can be seen. In looking at various sources there's just 30 or so galaxies visible in the northern hemisphere that are larger.

So the question is what's the minimum focal length I should consider to image the thousands of galaxies say between 1 to 4 arcminutes in size which could render some detail?

WAAT? - The Weekly Ask-Anything Thread! Week of 11 Oct, 2026 - 18 Oct, 2026

Greetings, /r/AskAstrophotography! Welcome to our Weekly Ask Anything Thread, also known as WAAT?

The purpose of WAATs is very simple : To welcome ANY user to ask ANY AP related question, regardless of how "silly" or "simple" he/she may think it is. It doesn't matter if the information is already in the FAQ, or in another thread, or available on another site.

Here's how it works :

  • Each week, AutoMod will start a new WAAT, and sticky it. The WAAT will remain stickied for the entire week.
  • ANYONE may, and is encouraged to ask ANY AP RELATED QUESTION
  • Ask your initial question as a top level comment.
  • Any negative or belittling responses will be immediately removed, and the poster warned not to repeat the behavior.
  • ANYONE may answer, but answers should be complete and thorough. Answers should not simply link to another thread or the FAQ. (Such a link may be included to provides extra details or "advanced" information, but the answer it self should completely and thoroughly address OP's question.)

​

Ask Anything!

Default sorting is Q&A. Don't forget to "Sort by New" to see what needs answering! :)

Please note: New WAATs go up around 7:30 pm US Mountain Time on Saturday, so asking a question on a Saturday afternoon may not get an answer. Be sure to check if a new WAAT has been recently posted, and ask your question again in the new thread if needed.

What is wrong with my equatorial mount setup? (Losmandy GM8)

I've only been using it for about a month or so, but it seems like the R.A. motor is slipping and when it isn't, the image doesn't track very well regardless. It will slip and catch itself before the target moves completely out of frame, or it will just stop tracking the R.A. completely. When I press on the controller I can hear it turning and making a buzzing sound while the worm gear stays still. I'm fairly certain it has something to do with the connection between the two, or maybe too much pressure is being put on the worm gear? When it is working, the image in my camera will slowly sway back and forth over the course of about 20 seconds, which isn't a huge deal for planetary photography but it limits my exposure to about 3-5s max. I have a theory as to the issue, as I'm using an Orion 10" f/3.9 Newtonian Astrograph with equipment on a Losmandy GM8 mount. The weight capacity is technically 30 pounds, and my equipment likely totals around 33-34 pounds, but I really don't like that answer because I love my 10" and I don't want to get another telescope or mount. Is it just a weight capacity issue?

Milky Way Timelapse

Hello, this is actually my first post on reddit. I recently moved into a new house and am away from the city lights, I live in a bortle 4-5. I have a Seestar S50 (I know its fake astrophotography). I want to start taking time lapses of the Milky Way and take long exposure shots in general of it. I dont have the money to be able to drop a couple thousand dollars on a good Camera due to my wife and I having a baby soon (our first). i want something small, but also capable, something that after i buy it I wont regret getting something a little more capable. I have been looking at the GoPro Mission 1 Pro, I have read a lot about it, and it seems really good, but also wanted to come onto here and see what everyone else thinks. The most i would spend realistically would be $1500. But I would really like to keep it under $1,000. More towards the GoPro price or less. I appreciate everyones time who comments!!!
