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?
