Manfred, I LOVE the California Nebula mosaic! I
think as I fall into the dark side, I'm going to be an H-Alpha
shooter.
Also, isn't the camera you are using a colour
camera?

California nebula and NGC281
Hi all,
Making deep sky images at full moon with a
Ha-filter is a funny thing. Last weekend I tried some mosaics for the first
time.
The first one is a 3 piece mosaic of the
California Nebula, done with my ZEISS SONAR 300/4, each image for 6 x
20 min with the Astronomik Ha-Filter. The moon was only about 15° away from
the nebula!
The second is a 2 piece mosaic of the NGC 281,
done with my VC200L at f/6.3, each image for 6 x 20 min with the Astronomik
Ha-Filter:
The HX916 needs a bit more exposure time than
other CCD-cameras at Ha, but it works. Before I got this CCD, the time
around full moon was the time for sleeping or other importand things. That
is definitly over!
Have fun,
Manfred
