Description

This has been an area I wanted to image for a while, and now that I have figured out how to put together mosaics correctly this was the spring to do it.  My focal length on my 2 bigger scopes at 715 & 750mm makes galaxy season a challenge being I have imaged what would be classed as the bigger galaxies already.  Putting LoTr 5 and NGC 4725 together seemed like a good plan.  This is a 2 panel mosaic where the GT102 collected the L data for both panels, the PHQ gathered the OIII, and the little FF65 did the RGB in OSC. The whole area fit in it's FOV as seen in Rev C, so that saved a bit of time not having to do 2 panels of RGB.  The OIII data was added to the RGB in Rev C to give it a bit more pop.  I have picked the cropped image as the final due the fact I needed to save these as PNG files. They are quite large but you can still go to full resolution on the cropped version.  Rev B is closer to the full field of view of the 2 panels that does not offer click and zoom.  When they were saved as a JPEG file there was some odd things happening to the background.

Info from Wikipedia:

LoTr 5 is a large, faint planetary nebula in the constellation of Coma Berenices. In 2018, its parallax was measured by Gaia, giving a distance of about 1,650 light-years.  As of 2018, LoTr 5 has the highest galactic latitude of any known planetary nebula, being only 1.5 degrees away from the galactic north pole.  Scientists noted this because if the distance of the nebula were found to be greater than a few hundred parsecs, then the gas from the nebula would be expanding into the galactic halo, where there is little interaction with the interstellar medium

NGC 4725 is an intermediatebarred spiral galaxy with a prominent ring structure.  NGC 4725 is the brightest member of the Coma I Group of the Coma-Sculptor Cloud, although it is relatively isolated from the other members of this group.  This galaxy is strongly disturbed and is interacting with neighboring spiral galaxy NGC 4747, with its spiral arms showing indications of warping.  A tidal plume extends from NGC 4747 toward NGC 4725.
