Nice results but I can't get NGC55 to open.

Sorry that you're having difficulty with the NGC 55 image. It opens just fine for me but I'll attach it again here to see if that helps.
Also added is another comparison taken last night.
Cheers

The months roll by and the sky turns. Some more screen captures with later processed versions from last night.
The dark nebula Barnard 35 is in Orion. The other two need no introduction.
Barnard 35 - average stack of 4 x 2 minute exposures. Horsehead - average stack of 4 x 2 minutes 30 seconds exposures M1 - average stack of 4 x 1 minute 30 seconds exposures.
Cheers

Beautiful results!!! Wish I had some sky! It's still cloudy down here. That's over 6 months now.

Had Been looks at zwo asiair or sw 72ed but can't justify the expense just now.. Won't be packing it in.. But talk about frustrated

Great images again "southern" ... always love the Horsie! It is always fun to use LR or PS (Lightroom or Photoshop) to post process a bit. You're always amazed to find heaps of "data" you didn't "see" in the first stretches and initial images you were once quite satisfied with. And all that playing and fiddling just in-the-end teaches us heaps .... which later becomes very useful knowledge when out there at night / doing outreach / EAA. Matter of fact, even the freebies like Windows Photo Gallery editor, the Mac iPhoto and many others do a great job with a minimum number of sliders and adjustments to confuse far less than LR or PS! LOL.
FYI, the "Magic Lantern" mob's software is considered to be upper end of the processing capabilities. But costs a bomb! Or does it!? .... Their single user/non commercial version is full featured and ... free! (Just in case you ever want to play with that ... but its a steeeeeep learning curve! LOL)
cheers Howie

Thank you Ken, Davy and Howie.
For the most part I use a very old version of Photoshop to smarten up the captured snapshots taken with the camera control and image acquisition program ToupSky. Photoshop 7 has mostly all I need by way of layers, selections and the usual run of post processing tools as well as a couple of Noel Carboni add-ons like his Astronomy Tools actions set and his AstroFlat Pro. But for on-the-fly work during an outreach session ToupSky itself has some useful post-processing options. After capturing a snapshot and saving it to file an additional copy can be made and displayed alongside the original. ToupSky has quite a full range of post-processing techniques that can be applied on a whole-of-image basis but I find that just using curves, brightness and contrast, some mild sharpening, and maybe some colour re-balancing (if needed) “brings out” the captured image well. Certainly well enough to impress the outreach visitors. And since these techniques can be applied very quickly (with the option of selective roll-back if necessary) it keeps the visitors entertained and perhaps a little better informed about the image content. Also, by flipping back and forth between the original and the adjusted versions they can see that one is not adding anything artificial – just getting them a better view.

I must be getting old. I get so caught up in the business of saving exposures to file for later processing that I keep on forgetting to save the accompanying screen grabs. So this time only the processed images using Photoshop. Sorry.
Three images from last night. Same imaging setup as before : SW PDS 150mm Newt GStar-Ex3 MFR5 fr giving x0.68 HEQ5 Pro (unguided)
A couple of the usual targets : M42 (part) – a combination of 4 x 40 secs + 4 x 1 min 20 secs + 4 x 2 mins 20 secs average stacks Running Man NGC 1977 – a combination of 4 x 2 mins 20 secs + 4 x 3 mins average stacks
Plus the Statue of Liberty Nebula and companion NGCs 3576 and 3603 combination of 4 x 2 mins 30 secs + 4 x 3 mins 15 secs average stacks
