The Pinwheel Galaxy from Tuesday night during the October 2017 trip to Starry Nights. This is 2.25 hrs exposure with the TOA 130, new Reducer, and Nikon D810A camera. I'm going to give it another go someday with PixInsight.
The blues are from hot, young stars. The reds are from star forming regions (H-alpha emission nebula - there's a big bright region on the right in this pic). Purple could indicate a bit of both, or else perhaps a color processing feature. I did some reprocessing vs. what's on my Facebook page to tame the purple a bit.
This galaxy is about 2.4 to 3 million light years away. You can make out red knots in this galaxy which are emission nebulae. This is the 2010 version; older versions below. You can judge if the new one is an improvement!
Above is a 70 frame image assembled from various imaging sessions.(5+ hours) Takahashi TOA 130 Telescope (a 5" APO refractor telescope), AP 900GTO mount, QHY8 CCD Camera, Other pictures from the camera are are here. Most of the image frames are from the Davis Mountains 2008 trip.
M33 Image above: 14 x 5 minute frames with the 1.6x, 28x5 minute frames with the flattener, for 3.5 hours total exposure. I went a bit heavy on the cyan during processing, but I kind of like it. Imaged with my Takahashi TOA 130 Telescope (a 5" APO refractor telescope), AP 900GTO mount, QHY8 CCD Camera. Other pictures from the camera are are here.
