Description

This is an image deliberately left large so people can pixel peep at the new OTA, a Stellarvue SVX152T.  This image is my "first light" image, taken over five nights ending October 27, 2022 for a total of around 34 hours of RGB data and 4 hours of Ha to add a bit of color to the star forming regions.  It is also completely uncropped, this it he full captured stacked frame, not even the edges trimmed.  I am quite impressed with how well the OTA and flattener handled the star shapes, and the detail to me is quite incredible, much more than I seem to get with my much longer C11 Edge (I need to compare same target at some point). 

This image is a lightly processed stack, with no star reduction (indeed, saturation near the end may have bloated them a bit).  The filter channels were combined for a luminance, no luminance filter was used.

I am personally not a fan of the purple look this object often gets - I do not know what the "real" colors are, but I tried to err a bit here on the side of blue and white, at the expense perhaps of some saturation.  I welcome comments or criticism. 

The real goal though was to see the detail.  If you choose to zoom in (it is a large, 80+ megabyte file) look around at some of the star forming regions around the edge. I think Vic at Stellarvue has done an incredible job with the optics here.

As I said, suggestions and criticisms welcome (and yes, for real viewing this should be reduced at least half if not a third, but... as I said, different purpose intended). 

If you care to see some blowups of detail without browsing around, here is an image on my smugmug page with callouts:
