Re: [APML] M57 RED info



I posted this to the SBIG list so I guess I better spill the beans here, too...
 
    The image is part of the RGB I am shooting of the Ring Nebula... the red was interesting enough to post by itself.
 
    Scope is the 14.5" f/8 Classical Cassegrain in my observatory in the foothills of the Sierra... not very good seeing and transparency (still too hot and there's still smoke in the air...).
 
    Camera is an SBIG ST-10E... 30 - 7 minute exposures with the red filter, lots of flats and darks as well... all the data fills up 7 100MB Zip discs and we still need the G and B components...
