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 NGC 891, a spiral galaxy in Andromeda; the galaxy is seen from an edge perspective. I captued this image using a C-11 SCT with an F/6.3 Reducer and an On Axis Guider (ONAG) onto which I connected my ATIK 460EX main imaging camera and Lodestar X2 guide camera.
Below is a summary of the length of exposure times and dates of capture for each of the color filters I used:
Red = 120 mins (8x15mins) on Mar 16 2017
Green = 120 mins (8x15mins) on Mar 22 2017
Blue = 75 mins (5x15mins) on Mar 23 2017
Total = 315 minutes (5 hours & 15 minutes)
NGC 891 is 123,000 light years in diameter which is about 20% greater than our Milky Way galaxy.
