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.
Interestingly there is no other region in the sky in the Milky Way that contains two optical Wolf Rayet nebulae close together although a really widefield mosaic could be done of NGC 3199 and the WR 16 nebula in Carina. Some images that might be of interest:

Thank you for viewing!

Hi,

There was only one usable guide star for my rig, so it's slightly cramped, but it's a beautiful galaxy!

M81 and M82 (Widefield) in Ursa Major by Radical Retinoscopy, on Flickr

A wide angle photo of the M81 and M82 galaxies in Ursa Major was made of 54 twenty second exposures (ISO 800). The images were taken with a Canon T2i and a 100 mm f/2.0 lens at f/2.8. Stacking was done using Nebulosity.

This image shows the field of Cassiopeia constellation, in a view containing a lot of Deep Sky Objects, as the Andromeda Galaxy, the Hearth Nebula, the Soul Nebula, and many others.

Wow everyone keeps producing stunning widefields with surprising composition and framing! The cluster near the centre of Sh2-202 is Stock 23, which is also known as Pazmino's Cluster.

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

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 October

Mars and the Stars

During the night, 25th of May 2014 around 0002 hours UT-3, It was a difficult night to do Astrophothos, humidity levels where right up on top, thats not a lacke, thats a flodded area caused by the continuous rains of the days before.

In the Image, Mars with Virgo and Coma Berenices, Vesta was around but I guess the exposure was not enough to get its light.

Image location: Lobos, Provincia de Buenos Aires Argentina.

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.

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!

Surrounded by Stars

One of my favorite imagenes, the highlights in the sky are the constellation of Canis Minor and its bright star Procyon above the light polluted city, above left M46 and M47, this area is sorrounded my the constellations of Monoceros, Canis Minor, Hydra, and Canis Major, but the highlighst are those mentioned at the beginning.
