Another ASI533MM first light - Nelly's Trunk

[david_taurus83]

After seeing @barkingsteve's first light initial results with this new camera, I decided to order one as have been mulling over it for a while since they were on pre-order but was waiting for somebody else to post up some images first. Thanks Steve!

Also a tip of the hat to 365 Astronomy for the speedy next day delivery.

Last night was clearish. With 3 hours of semi-darkness I decided to see if I could gather enough data for a complete image. I think the results speak for themselves. Very pleased even with so little data. Looks like this is going to be a popular camera.

12 x 300s each in Ha, OIII and SII, gain 100 and offset 50. Flats calibrated with a master bias and lights with a matching 300s master dark. Chucked everything into Pixinsights WBPP script and let it do everything including integration. Quick and dirty processing then to get some colour images.

Thanks for posting these @david_taurus83 (and @barkingsteve in his thread).

I've not had a chance to try mine out yet!

I managed to gather a few more subs on this last week. Below images are a combination of:

34 x 300s Ha (2hr 50)

26 x 300s OIII (2hr 10)

26 x 300s SII (2hr 10)

20 x 30s each RGB for stars

Just over 7 hours total integration under astronomical twilight.
