I can now see why its a hard target to get good data for, the faint arms really are very faint, and any moisture or muck in the sky will fade them out. I`ll get some more data on this when I can, but I am happy with this as a real first light with the TS OAG (even it is the last of the lot to get processed). Its a bit noisy, the faint bits have had a bit too much noise reduction, there is some gradient showing in the corenrs for some reason, but I dont think this current set of data going to get any better looking than this&#8230;.<\/p>\n<p>Mount: EQ6 via EQMOD<br \/>\nOTA: Skywatcher 190 MakNewt @ f\/5.3<br \/>\nGuiding: TS OAG + Starlight Xpress Lodestar<br \/>\nImaging: Starlight Xpress M25C + MaximDL, 9\u00c3\u2014900s (usable), Hutech IDAS LPR (101 bias, 101 flats)<br \/>\nOrchestrated: CDD Commander<br \/>\nStacked: DeepSkyStacker<\/p>\n<p style=\"text-align: center;\">(Click on image for larger version)<br \/>\n<a href=\"\/images\/messier\/20100416_m101_mid.jpg\"><img decoding=\"async\" loading=\"lazy\" class=\"aligncenter\" src=\"\/images\/messier\/20100416_m101_800.jpg\" alt=\"\" width=\"800\" height=\"527\" \/><\/a><\/p>\n<p style=\"text-align: center;\">Full Size Crop<br \/>\n<img decoding=\"async\" loading=\"lazy\" class=\"aligncenter\" src=\"\/images\/messier\/20100416_m101_closecrop.jpg\" alt=\"\" width=\"800\" height=\"770\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>This was the original target for the TS OAG equipped 190 MakNewt, but its been a chore to get this processed.
