This picture is never going to win any awards, ever... but for me it's a win.
I used Siril to stack them (no idea if I've done it correctly), 10x 150seconds exposure at 0degree cooler with the Atik 314+ clearglass filter.

I took the picture from home, full remote control 400+ miles away from my observatory.
No issues what-so-ever, from opening the lid to closing the lid and everything in the middle (ok, let's not talk about my guiding... another thread for this :blush: )


To Jasem, do you think we could have a forum section to show off our pictures (ok not mines... they still suck).

Nice shot indeed. The fact that you own a remote observatory, and that you are so successful with the "accessory" work on it prior to and after your sessions, is simply jaw-dropping for me. My observatory is in the backyard, and I'm not even trusting the scope automation at that distance. That forces respect :)

The issue with oblong stars is visible in your stack, yes. You're loosing much data because of this. All your subs are like this? As a first step, you should attempt different exposure durations to understand whether guiding is "bad" from the beginning and over the frame duration, or "worse" over the session duration. I also suggest using the guiding deviation check in the sequence plan: it will cancel captures when stars become wrong. Of course it will be frustrating if all of your captures are canceled, but it will allow you to progress towards the root cause.

Thanks, I've spent many years on this, the box itself could be improved as in design, I do have 2 more ideas to take this box to the next level if needed but I'll leave it as it is for now. Still checking and double checking with my script that the lid is fully open before deploying the scope, believe me it's nerves wrecking.
The next thing I need to test while I'm over there is the scheduler, to make sure that works well too. It should, but this isn't something I can blind test from here.


371 miles if you're a pigeon...
450 miles by car...




Some of my subs have oblong stars, I think it's due to the guiding problem I had during the session.
I'm also going to upgrade the mount with the belt mod.
Need to look into that "guiding deviation" you're talking about.

The guiding deviation management triggering capture abort and suspend is really an excellent feature. It removes the manual job of looking into every single sub to check their quality before stacking. Of course there are scripts that can do that for you as a post-processing step, but when imaging time can be saved right at the capture level, that's just awesome.

I can only emphasize what Eric said regarding the guiding deviation trigger. I use it on a regular basis. I deem it a reliable and extremely useful feature.

Short story for you: tonight I attempted to target that same galaxy out of curiosity because my FOV seems proper. At that time of the night, it is located on the meridian, north side.
I had not verified the eqmod RJ45 cable precisely enough, and it was not plugged in entirely. When the mount slewed down to the target, the mount disconnected. If I was 450 miles away, that would be a problem.
Well, it's somehow still a problem locally because of the amount of noise I make going out in the garden...
Only to realize, back to my controller computer, that the guider CCD connection had died too. After a few attempts at resetting the USB device without unplugging it, I called it quit.
That sort of USB issue would be fixed with a reboot, but I have a driver issue on my particular kernel which makes the remote indiserver lose wifi when the host soft-reboots. And I have no supply switch yet to do a hard-reboot.
Not ready for a remote observatory :)
