Seeing was not too bad for the Ha but quite poor for the RGB which made getting the RGB stars to match the Ha ones more difficult buuuut I got there....
High Ho Silver, oh, that doesnt work
Mike, them small pixels are showing their worth , , Dig the colour & a great smooth result from a nights worth ! Nice show . .
Maybe a couple more Galaxies out ther ya reckon - Go Get em ! Looking forward to em .

Glad you think so Greg, actually...if you look at Martins 2009 APOTY winning image meah... I think this holds up ok, for a quicky I NEED TO IMAGE A NEBULA fix

I just can't see it but there must be a galaxy somewhere through all that gas and dust. Otherwise why would you take sucha fantastic shot of a dark knight.

Oh yeah, there are galaxies in there Justin, don't worry...just need a good IR filter

Neigh, t'is just a Horseshead only so much one can do and I definitely wasn't going to hammer this one with long exposure, although some Lum might have been useful...because of the weather it took me 3 nights in the end anyway
Lovely result Mike.
FWIW I reckon a crop of a bit more background really makes the horse
sing...hmmm, bad choice of verb, I think you know what I mean.
A real close crop is awesome but a zoom back out just shows how deep
you really went, emphasising the dynamic range.
Anyway, WTH would I know, great job!
Your site mentions you didn't use darks, is there simply no need to at 20C below?
I notice when I do extreme stretching, even on the humble QHY-8
which gets down to around +/- 5 deg around zero, I can see that using darks helps a lot,
mainly because it calibrates out not only hot pixels, but readout noise?
Does the flat do that, excuse my ignorance, I've never used flats.

Oh yeah that area looks great in a 2deg field and I get that with the ProLine 16803 but the full frame link there is the field I have with the SX camera...so are you saying you prefer the full frame version over the crop? I only included the close crop cause, well, I was just..?.. horsing around

With the Starlightxpress it seems to not really benefit from darks. Unbeknownst to many imagers darks actually add noise as do flats, of course you can mitigate this effect largely by taking lots of darks and lots of flats to average out the noise but in the end they do add noise.. so in a perfect world they wouldn't be necessary...the answer is a nice low noise quiet chip (as is in in the SXVR-H694) then median combine out any residual hot pixels, have no vignetting and very clean filters and CCD window so flats are not necessary - easy! I am nearly there, I get a bit of vignetting from the small 1.25" filters so I have 36mm filters sitting here waiting to be installed.
I have been imaging at -20C since getting the camera earlier this year so while this low temp may assist I think this Sony chip is still very smooth even at higher temps.
It must be said that chips do have variations in sensitivity across their lattice and flats do address this and certainly with a big chip I think flats are probably more necessary but a small chip like the H694 I recon if you get all the variables mentioned above right you are home and hosed....super easy high class imaging
I have stretched the bejesus out of my data an not a single dust mote to be seen...touch wood..for when I change over filters
Nice resolution here Mike I would actually call it the pinky knight Not sure if I like the flossy color, I suppose this one got your tender side coming out during processing
