I am ready to move on......but my viewable part of the sky (from home) has limited me to this target.
Newtonian 8 inch F/3.9 Astrograph
Atlas Pro EQ/AZ mount
ASI1600MM-C imaging camera
L-RGB filters
Subs
36, 180" L
28, 240" R
25, 240" G
33, 240" B
Supporting files:
15, 180" and 20, 240" darks
40, flats for each filter (using a Neumann Flat Panel and SGP's Flat Wizard Sequence)
100, Bias
Images take over a two night period with pretty decent seeing conditions...all in all I had to cull 13 subs due to crap in the sky - planes - strange stars due to a guiding errors as in latent dithers - clouds.
Cropped out screwy stars on the corners that I was too lame to fix.
I am aware of the dust lanes I am missing - I reckon I need more subs as I had stretched this image to it's limits....with over 70 layers of alternating "levels and curves". When I get another clear night I plan to add another batch before the target works it's way out of my FOV.
I used SGP for my capture software......Pixinsight to sort things out - used batch processing script for registering, calibrating, and stacking. All processing was done in Photoshop CC.
I really like the camera but were it not for SGP and it's ability to run the imaging sessions unattended...and PixInsight's ability to prepare the images for processing - I would only use DSLR's.
It's very nice, is the lack of dust due to lum? Although you do have 36x180.
Remind me, what is SGP?
Sorry, Sequence Generator Pro. Yes, more L is needed.

That's really Beautiful Ed!
Move on to where? Are you a gnome living in a well?
While taking an Astronomy course at USC in the 70's, I stumbled across a big book of photographs of Galaxies. Used to sit there for hours marveling at the diversity of shapes and form.

I can relate! I still get gitty when I start an imaging session and see sub results - just knowing how long the light, that just struck my sensor, has been traveling continues to leave me dumbstruck. Not only are we looking deep into our universe's history but in the case of some of Hubble's photographs....deep enough to know some of the light has been traveling since the birth of our universe or close to. I remember see one faint Galaxy that looked pretty defined to me that was guestimated to be 13 plus billion years old - taken by Hubble.
