this is an object discovered
by Caroline Herschel, and included in the general Herschel catalog
as H VIII.77 describing the cluster only.
the nebulosity is Sharpless 2-142 .. this whisp of nebulosity
in Cephus is a bit fainter than I had expected... it didn't show
at all in 5 minute subs....
subtle reflection negulosity is beginning to show in some areas
in the longer exposure.
33 x 600 second subs, Vixen
ED80 at f7.5 riding on my Meade Classic LX200 12 inch, Hap mod
guided by PHD, DSI Pro on the 12 inch at f5.8 --- sky fair, a
bit of haze , and quarter moon for the first twelve,
much better without moon for the last 21 exposures but the sky
was a bit soft...
acquired, processed with large number bad pixel removal, calibrated
with flat, and stacked in Nebulosity, no darks
post processing in Photoshop CS3 (curves, gradient, final color
in background) , no sharpening or noise reduction
