What Telescope are you using...Very Nice Images and such short stacking time and subs...Pat Utah :)

See bottom left corner of Steph's images Pat for the equipment information. Very nice images captured with your 183C.

The Hypercam it's a good caméra for the price.

no, no, no,  not a motorola,  but a 12" Orion on EQ8 mount.

 

All final capture have the same total integration time (15min).

During stacking, I use various sub exposure (from 4 to 30 second) in the same stack, and various gain level depending exposure time.

I don’t know if it’s a good method, it’s the first time I test it, but it’s seem to have a good mix between sharpness with the short exposure and long exposure’s luminance.

I use a 0.70x focal reducer, uhc-s filter and darks.
 

Sorry, my english is not perfect.

Steph,

I liked your selection of targets, in particular NGC2146. So I added it to my list. Here is a shot from this week.
Rick

NGC2146, 30x30sec, Canon t4i unmodified, ISO6400, GSO coma corrector, 16" Sky Watcher collapsible Newtonian on a 1960s GEM upgraded for remote GoTo operation with stepper motors and OnStep controls. The image was processed/cropped on the fly with DSS/AT and saved as viewed.

Hi Rick, very nice NGC2146!

More good ones. I have a soft spot for the distant unusually shaped galaxies, especially when they are in groups. As luck would have it, I also got a shot of ARP 214 (NGC 3718), which I posted in this thread. https://www.cloudyni...lery/?p=9077300

Hi eveybody,

M101, 17 minutes total integration time, with various sub exposures times in the same stack.

Steph. You say that you are using various sub exposure times in the same stack. Are you doing this on the fly (as you are observing), or at some later time? What software are you using to do this?

Yes, on the fly with Sharpcap, various sub exposure times, various gain level.

 

You can also stack with darks or not, you can change all the settings, except the color space, binning and the ROI.

These 12 "that you use are wonderful, for this type of weak and small objects gives an impressive detail.

 

Does this combination give you some coma aberration at the edges?
