M81 and M82

[AMcD]

This is my rendition of M81 and M82, comprising a little over 9 hours of 180s integrations taken with a QHY8 on a TS152 achromatic refractor mounted on a Losmandy G11.  The image was acquired over the past couple of nights using SGPro and PHD2 and was processed in PS.  The image is the first part of an experiment to see whether I get better results on galaxies with no filter or with a broadband LP filter.  This is the unfiltered version.  When the postman brings an Optolong L-Pro I will do a 9 hour version with that filter and compare them 😀
