Normally when I image at f/6.3 I use a manual 1.25" filter wheel with Orion LRGB filters. This time I used a thread adapter on my f/6.3 T-Ring and attached my Hyperstar filter slider. That way I used the better 2" Baader filters with a larger aperture and better even illumination on the sensor. I think the colors came out better too.

 

M15 Globular Cluster in Pegasus
C14 @ f/6.3, ASI1600MM-c, Baader 2" RGB filters
75 subs Lum and 25 RGB @ 30 seconds each

Beautiful image that is my favorite globular cluster.  That is usually the first object I view thru my 18" dob.  Keep up the great work. waytogo.gif

If you were using a 0.63X focal reducer on a C14, wouldn’t your reduction be just under F7?  The C14 is F11.

Yes when I say f/6.3 I merely mention the reducer. It would be f/6.9 @ 2463mm on a C14.

One thing to mention, is that there is a planetary nebula in M15. Pretty easy to spot.
