and here is another bubble from last night


Robert Pitt
 

I used a C9.25 f/10 with LPro filter to get this last night. 40 subs used at
3 min each, OSC ASI2600MC). Now to try to figure out how to blend this with
the narrowband image.... Also did M33 OSC last night, but too many
processing artifacts to show, so need to redo the processing for that
one....
Regards,
Bob
