Hi, I am guessing tonight is another wash out seeing wise. Looks like lots of high clouds just like last night. Bernard http://www.azstarman.net/CDK/index.html This email has been checked for viruses

Continuing on Bernard’s message today (and the others from the previous few weeks) on seeing. I could be wrong but I think an on-site seeing monitor would help end some of the frustration. Several peo

Hi, This is an image of M78. Actually, M78 is the brightest reflection nebula (blue nebula near the center) of a nebula complex that includes NGC 2064 (the red nebula on the left of the image), NGC 20

Hi all: I think I was able to find one of the fragments (141Pb) recently broken off from 141P Machholz: http://www.greggsastronomy.com/IMAGES/141P-Machholz-Lfrag.jpg Luminance only, 20 x 60sec from Da

Hi, This is an image of NGC 1291. It is a ring galaxy with a unique inner bar structure and an outer ring structure. It is believed that ring galaxies form when a smaller galaxy passes through the cen

Hi, Did anyone but me get horrible results last night. Some of my subs had FWHM of 5. Clear skies said the seeing was supposed to be average. Did anyone else get bad results or is it just me? Thanks,

Gregg, This is really nice. I was surprised to find that tail as well when I started imaging this one a year (or more ago). I eventually found a paper on it but it seemed like my image showed more tha

Hi all: Arp's catalog of peculiar galaxies lists 299 as a 'double' galaxy consisting of NGC3690E and 3690W, interacting with IC 694 (alsoVV 18c). The galaxies are in the upper left quadrant of this im
