Hi, this question has probably been done to death here, but can I ask the community to help me decide on a new camera?
After struggling with my very glitchy QHY5LIIc camera for a while, as well as having a forced break from astronomy, I have decided to get a new camera. After all the problems I've been having with the QHY, I really don't want to use this manufacturer again. I know lots of people use them quite happily, but once bitten ...
I have been looking at the ZWO cameras - OSC, as I haven't the time, clear skies, or patients to do LRGB imaging!
I have about £250 to spend, which I may be able to push to £300 if I wait a bit. ? So I've been looking at the ASI224MC, ASI290MC and the ASI178MC cameras.
I mainly do planetary/Luna imaging, but I have also dabbled in a bit of DSO and would like to continue with both. I have a C9.25 and a ST80 guide scope. I know these aren't ideal for DSOs but please humour me!
I think from the specs/information that the 224 is probably the best option. Although the resolution and QE are the worst of the three, the well depth and read noise are the best and the fps is pretty good too.
I don't know if there are better/cheaper cameras using the same chips, such as Altair's range. I just don't want to make the same mistake that I did with the QHY!n
Any help/advice you can give will be much appreciated.?
Second time I undertake this kind of endeavour. Many many movies were shot. Over 300Gb of data. Stitching was done by hand. in adobe Photoshop.
CFF 300f//20 cassegrain
ASI174MM with Astronomik proplanet807
processing using Autostakkert, lynkeos and adobe photoshop.
Image is a wee bit too large to add to post direclty. hence just the link.
Make sure to check out at full res.
The Tadpole Nebula and the Flaming Star Nebula captured over three nights of the unexpected nice weather we had a couple of weeks ago.
A number of firsts with this image:
1. My first mosaic - keeping it simple with two panes!
2. First time I left my imaging rig outside... (I used a telegizmo cover) and it was perfect, allowing me to get imaging very quickly on each night
3. First time using powerful scripting tools in my capture software, APT, to move to the second pane and starting imaging automatically...worked really well!
APP was used for pre-processing and stitching the mosaic together, while Pixinsight was used for image processing. A total of 10.9 hours integration time.

Thanks for looking!
Hi everyone. So I'm looking to do some form of mosaic over the weekend.
Is it better to stack in mosaic mode in DSS or merge in photoshop?
And is there any other advice for me as this is mainly a learning evening for me so any tips would help.
Also do I need just 1 set of calibration frames or a set for each part of the mosaic.
