Hi Alan;
Exceptional images. I wonder what causes the bright spots on the north and south limbs?
Shooting at 10.14 meter focal length? What sort of exposure were you using?
It might actually stop snowing / raining / fogging / blowing here on thursday, so I can use my scope after a 7 week imaging drought.
Thanks for sharing..

Hi all,
After struggling with light throughput from my 8nm Baader K-Line filter, I decided to follow advice and purchase a wider band UV filter from Astrodon. These results were obtained March 22 using my 10" Mak/Cass at f40 and Flea3 monochrome camera. Image capture and stacking in Astro IIDC, processing in Astro IIDC and Adobe Photoshop CS3. I shot the UV data about an hour and a half before sunset.
