The streak is not a perfect straight line due to variations in atmospheric seeing across its extent. It is physically impossible for the object to have been wobbling enough to cause visible ...

Nice image! I, too, am impressed with your results using the teleconverter. Which version of the TC do you have -- II or III? I am curious about your plan to use a front aperture mask instead of ...

Great image!

Roger, Based on your comments I reprocessed this image. I adapted your technique for my PixInsight workflow. While I can probably do more to perfect it, I am already seeing significant improvement. ...

Thank you! (Of course, the blue detail in the veil is from OIII emission; the H-alpha (red) is what is lacking.)

Thank you. If you use PixInsight, experiment with masked stretch or apply your own star mask when performing histogram transformation. John

The photo of the Veil Nebula was captured from suburban Pittsburgh August 29 using a Canon 7D Mark II camera and 200mm f/2.8 lens. It is a combination of 160 one-minute exposures at f/3.2 and ISO ...

P.S. You can submit your image at nova.astrometry.net to determine where you were pointed.

I think you need more exposure time. I imaged the Cygnus Milky Way Tuesday night with a total of 2.7 hours of exposure (https://goo.gl/CwuHgq). Granted, I'm under light-polluted suburban skies so ...

Interesting. I'd be interested to know more about your technique. Have you written about it somewhere?

Nice image of the Veil! You picked up more H-alpha than I did recently with a Canon 7Dii and 200mm lens. The photo was taken from my driveway in suburban Pittsburgh using a Canon 7D2 camera and ...

No, the strict light rules apply to the Astronomy Field (south side of road). Same with the need to be registered for the star party. Enjoy!

A few more suggestions: If you're going next weekend, be aware that the Black Forest Star Party is happening and registration is required. They have already sold out. If you want to use the ...
