The Clear Sky Evening
NGC 6914
Astrophoto NGC 6914 Clear Sky 18.
The primary target of my astrophoto evening (NGC 6914) is, for a 600mm telescope with an APS-C chip, a bit small. But i like the contrast of the blue reflection nebula and the red emission nebulae. Here the high resolution Astrophoto on Flickr:
Lessons Learned
Lightreflection
In the upper left part of the picture is a lightreflection i never had before. Possibly the caused of a nearby lamp. I ll have to see, if this is a one time-effect or if this is caused by the combination of the lamp and my new flattener.
Flattener
This picture is the 1st one i shoot with a flattener in my refractor, the TSFlat2. The stars are round! Even in the corners.
Exposure time
The total exposure time of only about 120 minutes is really a bit too short. It would be good for the image if i could double the exposure time. But taking the weather sitution into count, i can be very pleased with the result.
