I really like seeing widefields of regions in Cygnus, Cepheus and Cassiopeia (as well as many other constellations) and this seems different yet familiar at the same time! You should have a link to a larger image, the attached one is small. This is one of the very few images that includes two Wolf Rayet nebulae, the Crescent Nebula and the WR nebula associated with WR 134, the bluish arc that can be seen near the right side. You can also see a closeup of the region south of the red blob (emission nebula Sh2-104) near the bottom right corner by Bernhard Hubl here.cfm2004 wrote:September/October 2014

Thanks very much starsurfer and for your links and the other information. It was my intention to include vdB14 and vdB15 but the weather hasn't cooperated here in Michigan since late Octoberstarsurfer wrote:terry.hancock wrote:4 panel Mosaic consisting of RGB+H-Alpha data, 6792x4188 pixels.

There is actually another bonus surprise in your image! The faint round nebula near the top left corner is the planetary nebula HDW 2, which is also known as Sh2-200. Don Goldman released a rare closeup of it a few years ago: http://www.astrodonimaging.com/gallery/ ... ?imgID=250
If you add another frame to the left, you could also include the reflection nebulae vdB14 and vdB15. Check out this widefield by John Davis: http://www.bucksnortobservatory.com/dee ... 4_15.shtml
Finally, Fabian Neyer did a mosaic of the Heart and Soul Nebulae: http://www.starpointing.com/ccd/heartsoul.html

Wonderful picture, Terry!

This is a very nice image! The narrowband data has made a hidden secret more apparent, a small planetary nebula catalogued as WeBo 1. See the attached crop for a closer view!terry.hancock wrote:This Hubble Palette image combines all data captured from my backyard observatory in sunny Fremont, Michigan USA, October 22nd 2014 using QHY11/TAK E-180 and data collected in 2012 using QHY9/TMB92SS you can see my earlier data here: https://www.flickr.com/photos/terryhanc ... otostream/
I have also added data from the RGB version for more natural looking star color.
