I set off to capture the Leo Triplet after my prior targets in Orion and Monoceros had set. I captured the data over 2 nights using the 294 MC OSC. When I looked at the data initially, I noticed a faint Ha signal the upper central region. After I did a basic ABE,  my image seemed to be significantly overstretched with an odd background. My initial impression lead me to think I had a flat calibration issue. I proceeded to shoot a new set of flats, dark flats, and darks. This effort was to no avail and the same pattern emerged. 

I searched through astrobin along with other images and found info about a faint IFN component in the area. Most images of the Leo triplet have a dark black point and the ones that did not did show the same pattern as I had in my image.  

I hoped that I would be able to get some luminance and Ha data with my 294 MM over the last 2 months, but perpetual cloudy nights win again.
I had a difficult time processing the image and completed 8 different edits to try to find the balance of IFN and HA collected.  The image is cropped in quite a bit with the mouse over showing the wider field image. 

The hamburger galaxy, NGC 3628, in the top left of the image is a spiral galaxy  edge on that is approximately 35 million light years from earth.  The 160,000 light year wide galaxy has an even more impressive stellar stream that stretches an additional 400,000 light years to the upper left of the image.  This stream contains a bright cluster NGC3628-UCD1  just out of the galaxy which is the subject of multiple papers. This is though to be a stripped core of a dwarf galaxy.   In the paper from 2015, "NGC 3628-USCD1: A possible ew Cen Analog Embedded in a Stellar Stream" , Jennings et al. discussed this cluster in detail. Furthermore, the very end of the stellar streams appears to have a possible irregular dwarf galaxy at the end, but I could not find any information on it or what is thought to cause the stellar stream. I have attached a inverted monochrome image to illustrate this area, UCD1, as well as the IFN in this portion of the night sky. 

M66 in the lower left is a beautiful and colorful mostly face on spiral galaxy with distinct star forming areas and bright blue young star clusters.  This galaxy is the same distance as NGC 3628, but smaller measuring 90,000 light years in diameter. 

M65 in the lower right is another spiral galaxy slightly further from the other to prominent galaxies at 41 million light years from Earth, measuring 120,000 light years in diameter. 

The Integrated Flux Nebula is a combination "high latitude" nebula or even intergalactic material above the central disc of the Milky Way. The dust is composed of mostly hydrogen and smaller portions of oxygen and carbon. The nebula is illuminated not by a star or a cluster of stars, but instead by the whole Milky Way.
