View Full Version here: : First(ish) light with RASA 8 and ASI 533MC
Here is Eta Carinae taken with a RASA 8 and ASI533MC. Used Sharpcap for live stacking - total exposure was 100 odd minutes. Used APP for background calibration.
Nothing earth shattering, but the workflow was really enjoyable! 30 second exposures, and no autoguiding. ;)

Super sharp. :thumbsup: Now your only problem will be hard drive space. ;)

30 Sec exposures? :eyepop:
Amazing, what's the f ratio 2.8 or similar?
Are the stars round in all four corners?
Looking forward to seeing what you come up with. :):thumbsup:

gee Andy you must live in the wardrobe, surely you have heard of these scopes (https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=&cad=rja&uact=8&ved=2ahUKEwjK8q-G0qTwAhXVcn0KHTofCdsQFjAFegQIBxAD&url=https%3A%2F%2Fcelestron-site-support-files.s3.amazonaws.com%2Fsupport_fi les%2FRASA_White_Paper_2020_Web.pdf&usg=AOvVaw1WlVIh5qU8OI5XtKYPId9k)
great start Tim looks awesome
Excellent result Tim, and encouraging at several levels. I absolutely dig the enjoyable-workflow bit, especially when something as good as this comes out. You also appear to have put some thought into how the spikes work out. I think my yet-to-be completed "poor man's RASA" setup (around a hyperstarred C6) will be visiting that area also, once everything is up and running. Inititial trials suggest f/2 is indeed where the fun is. One image, one session, done and done! :thumbsup:
So I did have a close look at it today - one side appears to have some slight star elongation on the edge, so I will need to look at it. Might need some collimation, or see if I can adjust the tilt of the camera somehow.

Don't touch the collimation, it is tilt. Check if your distances are right and if the camera is done up snugly
