[APML] M57 with simple equipment



Hi all,
 
I think its of interest for everyone who takes astrophotos:

Here a simple webcam operates as a camera (only 30$) with change to take long exposures but with NO cooling.
131 images (30" exp. each) are summed up with software MIRA and corrected for dark current.
I take it from a light polluted place with stars of 4m are visible.
Telescope: 8" Schmidt Cass. with f/10
 
best regards
