My name is Peter Nerbun. I'm an astrophotographer who lives in
Perry Hall, Maryland in the USA.
Here are the astrophotos I captured with my C11 Schmidt Cassegrain Telescope (SCT) and ATIK 460EX astronomy camera. Please click on any one of the images to see a description of how and when I captured that particular image. After you've read the description please click on the green oval icon at the top left corner of this page, this will take you back to the page showing all of my astrophoto images.
This is my image of the Trifid Nebula (M20 which I captured with a C-11 SCT in L_HA-R_OIII_B on the following dates including filter exposure times and number of frames per filter on each day:
H-alpha: Sep 4/5 2017: 13x5mins = 65mins
Sep 9/10: 15x5mins = 75mins
Total = 140mins
O-III: Sep 7 2017: 4x10mins = 40mins
Red: Sep 20 2017: 13x6mins = 78mins
Blue: Sep 16 2017: 16x5mins
Sep 17 2017: 15x5mins
Sep 19 2017: 19x6mins
Sep 24 2017: 8x12mins
Total = 365mins
Luminance: Sep 15 2017: 18x5mins + 1x4mins
Sep 23 2017: 15x6mins
Total = 184mins
Total Integration Time = 807 minutes = 13.45 hours
In addition to the C-11 SCT I used an ATIK460EX main imaging camera, a Lodestar X2 guide camera, and On Axis Guider (ONAG), an F/6.3 Reducer and a Starlight Instruments motorized programmable focuser control system.
