Benson, AZ 85602 hm ph: 520-586-2244 Good shot, Jim. You forgot to mention that the recent SN in M101 is still quite obvious as a very blue object left aways from the nucleus. It has faded quite a bit because it was brighter than the two guardian stars above and below it. Do you have a coma corrector? Clear skies, Wayne (aka Mr. Galaxy) ---------- Original Message ---------- From: "Jim Waters" <james.t.waters@xxxxxxx> To: <EVAC@xxxxxxxxxxxxxx>, <az-observing@xxxxxxxxxxxxx> Subject: [AZ-Observing] M101 Uploaded to Pbase Date: Fri, 4 May 2012 21:39:09 -0700 All; I uploaded an image I took of M101 last month to PBase. http://www.pbase.com/jtwaters/image/143095888 I could have used another 60 minutes of �Lights� to increase detail and color but M101 was approaching the zenith. There�s also some differential flexure between the imaging scope and guiding setup. Focus was a bit off. Tracking was shot at 2 second intervals and was OK. It could have been better. I think the tracking star was SAO 28988. The stock AstroTech focuser was replaced with a MoonLite focuser. No filters were used. The image was shot ~11 miles SE of Fredericksen Meadow through some camp-fire smoke (34�34�22.98N/111�19�59.17W). There was little to no wind. The image is JPEG � 8 Bit. In all I am happy with the image. In the image I can identify the following NGC objects: - NGC 5474 Spiral Galaxy - NGC 5447 - NGC 5461 - NGC 5462 - NGC 5471 - NGC 5449 - NGC 5451 - NGC 5477 Spiral Galaxy - NGC 5485 Spiral Galaxy - NGC 5473 Elliptical Galaxy - NGC 5422 Spiral Galaxy Imaging Scope � 8� F/4 AstroTech with MPCC Guide Scope � 80mm F/5 Refractor Guider � Orion SSAG, PHD Guide 1.13.4 Mount � Celestron CGEM (stock mount) Camera � Canon T3i (G.
