Lagoon

Just my basic EAA work flow: Sharp cap stacking, Sharpening and Autostretch.
Image Processed very basically in PhotoShop.
50x8s images

C925 0.67FR, ASI 294 MC Pro, lights only.

I always save the stack, but never process them, will give it a try.

Thanks for looking

Very detailed live stack. You have that down to a fine art.

Thanks Ray,

SharpCap is pretty amazing software for $10 per year.
The image is pretty much how it developed live.
I use the auto color balance, and start with auto stretch, then play with the sliders from there, (There’s slightly more to it, but it’s all pretty basic), to observe the object. Once I finish observing the object I reduce the stretch to get a “balanced pleasing image” and save it.

Rarely (as in this case) I will import the png into photoshop, and have a play.

This was done in photoshop express on the iPad. I’m embarrassed to admit, it took 5minutes! Crop....one of the hdr presets....spot healing tool to remove some hot pixel trails. And that’s it.....of course it’s not fancy or skillful astrophotography, but it’s a nice record of my observing session, and a reminder of what was in my minds eye when observing at the eye piece.

Cheers

Hemi

Thanks Fernando,
Yes 8s subs, gain at 300, only light frames, 294 cooled to 0 degrees (ambient was about 24), bortle 5 or 6.

I’m not sure what to make of the 294, it’s my only Astro camera. For 8s I feel I get far too many hot pixel worms.

I’ve just recently setup a skyshed pod and pier, and the polar alignment is a bit iffy, I can manage about 30s unguided only at the moment, and their not great! But even 30s subs seem overly long for EAA. 8s is perfect for these brighter object.

First try on observing dragons last night, it was very disappointing after seeing everyone’s recent renditions. The 8s/300 gain, definitely wasn’t the go.

Very nice M8. Great details. You can probably color balance it a little.

Thanks Marc,

When you say color balance, do you mean adjusting so that RGB peaks all align?

Thanks Hemi
