The last several weeks have not offered very many opportunities for imaging. Nevertheless, during the occasional clear night, I have managed to get a preview of the summer sky. Most of the following images have a rather low total exposure time. This is because the objects in question do not rise until well after midnight. As summer progresses and these objects rise earlier, I will increase the total exposure time. Each of the following images is composed of 300 second sub-exposures taken with the Starshoot Pro and the 6" LXD-75. All are guided by a DSI Pro through a 70mm refractor piggybacked on the LXD-75.
M16
A total of 35 minutes of exposure.
M17
About 25 minutes total exposure time.
M8
Twenty-five minutes of exposure time. The 300 second sub-exposures work nicely to tease out the nebula's detail.
NGC 6992
NGC 6992
The Starshoot's large chip makes it possible to capture the entire arc of this part of the Veil Nebula. 50 minutes total exposure time.
The night before, I failed to take a test shot of the target before beginning the long-exposures, trusting the LXD's pointing accuracy. The LXD did put the object in the FOV, but left it far too low in the image. I should have centered the object before beginning the long-exposures.
45 minutes total exposure.
