The two brightest stars above are (from right to left) Deneb and Sadr. They form the head to neck part of the Cygnus (Swan) constellation.


There are several named nebulas visible in this image. Below Deneb is the North American nebula (NGC 7000) and the Pelican nebula (IC 5067). Just below the Pelican is IC 5068. Gamma Cygnus nebula (IC 1318) surrounds Sadr. At the left edge in level with Sadr, the Crescent nebula (NGC 6888) is just visible

Matt:
Did not expect that the AstroTrac would work that good, ¿was it guided somehow?
Regards,
Eric.

Hi Matt:
An English friend, past Christmas gave me a Astrotrac, that not yet I have tried, but after seeing this so extraordinary photo that you display I will prove, it as soon as possible.
Excellent photo.
Many greetings
Cesar

Eric, Cesar and Hunter - thank you.


No guiding with the Astrotrac. It works realy great, there is actually some star trailing if you enlarge to the "real" size, but it the Astrotrac is not to blame for it. The polar alignement scope has a glass plate with pictures where to put polaris etc. That plate must be exactly in the midle.


After reading a post by Hunter (thanks) I realised that that might be the problem I had so I checked it and found that it was not in the midle.


I have corrected it now but it is too light to image anything here at Lat N59 so I will have to wait.


For processing details go to [ link ] , klick the moon and then processing.
