M33 - The Triangulum Galaxy

Hi fellow Astrophotographers,

after moving from the city to the suburb I am now happy to image broadband targets again. This is around 5 hours from my new garden. I was only able to image M33 before it hit it's peak and I think the resolution took a hit because of that. The change of correctors shows a work in progress. The Schmidt Newtonian never got a dedicated Corrector for it's remaining Coma and astigmatism and I am still figuring out the spacing after 2 years. The Paracorrs Illumination is much better than the Maxfield's. Both coma correctors work at around 5mm less of spacing between corrector and sensor right now. CS, 

Ben

Post processing steps:

• Stacked in APP with all auto settings except for dynamic distortion correction turned on
• remove light pollution in APP
• star color calibration in APP
• worked on colors in Lightroom and used eliptical luminance masked adjustments to tame the background
• starsize reduction in Photoshop with starmask created with threshhold adjustment layer on top of difference layer of the image and a descratched version of the image. The actual star size reduction was done with a minmum filter.
• final touch ups and cropping in Lightroom
