Description

Revision-D   5-15-22  Worked on detail and improving color contrast.

Revision-C  Per Nicola's request, I have made an effort to reveal more detail in the outer spiral structure -- although at this point I feel that I am pushing the image data too far.  May be time for a complete re-process.  That said...  It's all fun.

Revision 4-23-22   Adjusted the color balance and contrast to be a slightly more subtle. 

This revised image of M94 Spiral Galaxy represents several nights of image data acquisition for about 18 hours of data.   My goal in this image processing was to bring out the inner and outer Rings structure of this galaxy and to enhance the Ha present in the concentrated central core.  

Imaged with my 24" f8 RC from the Sagrada Observatory, with an FLI_PL-09000 CCD camera, GenII Filters.   Seeing conditions for this image data were in the 3 to 4 arc secs range, which were not the best conditions.  So if seeing improves, I would like to reimage this interesting object.
