This is a “first light” image taken with my new wide-field setup.
Here we have the star Sadr in the constellation of Cygnus. Using narrowband Ha (56mins) and Oiii (30mins) filters I’ve captured the glowing dust in the region surrounding the star. Not bad for a first image. This widefield shot shows Sadr in the middle surrounded by nebula (IC 1318) but also included is the so-called propeller (top-left), many dark regions, NGC 6914 a blue reflection nebula (very faint, middle left region) and the Crescent nebula (NGC 6888, top right).
This lens is fantastic for grabbing photons quickly from a very wide field of view. I plan many more sessions with it and will probably revisit this area when we have astronomical dark back in August.
I’ve owned the 135mm for over 2 yrs but just didn’t have the time to put together a rig for it. I’ll make a separate blog entry on the construction of the mount.
