Cygnus H-alpha and Veil Nebula

Posted By Roland Christen
That is a very nice composition. Sometimes stepping back reveals detail that is lost when shooting narrow fields at higher resolution.

I misnamed it. It will be the GTX (a car I always lusted after)

I just finished a 4 panel mosaic of this area in H-a. Your image is the area just south of Sadr, about in the middle of my image. My image is only at 25% of the original size in order to fit here on Astromart. Will post a larger one in the gallery later.

Hershel Wedge

Posted By Roland Christen
Not to worry. Heat is not concentrated up front. heat builds up at the focus point, and the wedge is designed to dissipate it.

Pretty nice considering that you are not shooting in H-a narrowband. You might try shooting in H-a and add as luminance to this image.
