 Yeeeeeeeeee Haaaaaaaaaaaaaaaaaa!!!!!    A clear night!   Will wonders never cease.
 
I set up my scope (my Orion 80mm refractor on a Celestron 4se mount) and imaging equipment about 9:45pm.......so anxious to get going, I 3-star aligned in alt-az mode.  
Decided to take another shot at M81.   Tried ten different sequences......basically 25-30 exposures at 15 seconds each.   Unsuccessful.   The core is bright and easily imaged, but the spiral arms are whispy and faint......very difficult to get them to stand out against a light-polluted sky.   I will try again, but from a dark sky location.......with my scope polar-aligned carefully.  Hopefully I can push the exposures to 30 seconds without getting oblong stars.
 
I was a little more successful with M82.   Although I think I might get a little more detail with my 104mm Mak-Cass at 1300mm focal length.   The object's apparent size is small.   I am shooting at approximately 80x with the 80mm.   I would be shooting at approx 260x with the Mak.  
 
Once again, I struggled with the Camera (Meade DSI) and Meade's Autostar software.   Ever since I updated the software from Meade's website, all the settings react differently......and the camera does not seem as sensitive.  (may be my imagination...not sure)   I finally called it a night at 3:00am.  
 
Looking forward to another clear night.......Jupiter had climbed to about 25 degress above the horizon when I went inside.   Looking forward to a night of steady seeing for some webcam imaging of the GRS (Great Red Spot).

Thank you, Sir. Glad you liked them. I don't pretend that my pictures compare to some of the better ones posted here and elsewhere (see Neil Heacock's images here), but all in all, considering my level of equipment(cheap)and my fairly haphazrd methods, they aren't too bad. I have fun.

The weather Gods have not smiled kindly on the Northwest this spring, but hopefully things will improve. The underside of clouds aren't very interesting. LOL

Hi Barry,

Thank you for sharing M82 with us. I think they look great.

*sarcasm on*
Sorry about the clear night...that was a mistake on the part of the weather Gods. You should have had clouds.
*sarcasm off*

Clear Skies!

Gene
