Description

Here is my image of Bodes Nebulae with an attempt incorporate the Integrated Flux Nebula (IFN).
I took all of the LRGB data back in February, but have use the last two clear full moon nights to capture Ha only to add to the image,
The data was captured using a Sharpstar SCA240 with a ASI 2600MM camera. Integration frames used were
L  180 sec x 30
R  180 sec x 40
G 180 sec x 29
B  180 sec x 24
Ha 300 sec x 64, 600 sec x 73

A challenge to add the Ha, IFN and have good contrast on the galaxies.
I did have many more L sub-frames but with a large transient Mott on them I decided not to use them.
