Hello folks I was wondering about the following thing. The ASI294 has a pixel size of 4.63um, now, when I set it as a guide cam in PHD, it's pixel size gets autopopulated to 2.21 um. Why is that, and would that influence my guiding, all other things being equal? Regs. Andy

Hello Folks Maybe someone on here knows about Filterwheel problems. I had, until recently, a well functioning Atik EFW filterwheel working with APT through Ascom(I believe it was the x64 version with 32 bit support). However, Firecapture wouldn't detect it, so of course I had to experiment, and now nothing works, neither APT, nor Firecapture. Having read extensively on the web did not solve my problems (re-deinstalling, Core, legacy atik s/w, device manager, reading on here, etc.) Now I have deinstalled it, and can't find my disk w/ the old driver anymore, nor does one seem to be provided anywhere on the web (Atik, Ascom, Optec). The Atik Artemis s/w still works, and I have the driver on another computer, however, I can't locate the driver location I looked in device manager and sys/32?), all I see is my driver in the installed programs ( I had the bright idea to transfer it from one computer to another one. It's the ASCOM EFW2 filterwheel driver 1.1.0.0 . Does anyone know how I can get this driver back, or a solution that I can at least reintegrate my driver on one computer with APT on the other one. Had I known the headache this would cause me, I'd have left it alone. Update: I have meanwhile solved this problem by finding the driver on the other computer, copied and pasted into the right place, and also deleting an older, similar driver in the target folder (The Ascom filterwheel folder). Regards Andy

What Ruud said, awesome image.

Need to get me a cardboard box, those electric dohickeys like star adventurer and 1 min. exposures somehow aren't working out as well for me. 🤣

I finally got my color for M51ñ it started out slightly problematic, this is as well as I could catch up in a first process. There´s a small ha component in it, I just couldn't get too heavy handed with 6 5 min. ha subs. Altogether about 5hrs LhaRGB in 10, 5, 3 and 1 min. L subs, 9x9x9 RGB, 6 ha ones. As always, no calibration frames, after a night in the cold far away, I didn't want to stick around for dawn twilight flats. 1LhaRGB, 1 HaRGB. - Andy -

Easily remedied With the move tool, on can align layers properly. Or >edit > transform, if they are of different sizes.

Hi If my first image had looked like that, I'd have been happy. As it is, all I got was some greenish fuzz, otherwise known as the Andromeda Galaxy. Way to go. I used to take my DSLR flats after a session, in the morning in brighter twilight, scope pointed at an evenly illuminated clear sky. Dunno whether I'd take darks half before a session, why introduce heating of the chip right off the bat? I may be totally off here, but the doubled-up stars don't seem to be a stacking problem to me, rather something due to a sudden very small mount movement (gust of wind? Cable snag? Something slightly banging against the mount?) At 10 images (lights), the "reject sigma" algorithm in Deepsky Stacker should be able to filter out small imperfections. - Andy -

I've been having my eye on this baby for awhile now, the CEM60 EC sounds like a winner. Now all I need with it are a house in the South West US, or Spain. - Andy -
