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 L-HA_R_G_B image of NGC 2903, a Spiral Galaxy in Leo. I captured this luminance image with a C-11 SCT on April 21 & May 2/3 2018; I recorded 21 five minute luminance exposures on Apr 21 and 15 seven minute exposures on May 2-3 for a total of 210 minutes. This galaxy is similar to our own Milky Way in that they both have spiral structure with a central bar. Both galaxies are roughly the same size (80,000 LY for NGC 2903 vs 100,000 LY for the Milky Way). I also recorded red, green blue and HA filter images on Jun 15 2018 and earlier. NGC 2903 is a face-on galaxy located 20.5 million LY from Earth and measures 12.6 x 6.6 arcminutes in angular width.

Both galaxies are roughly the same size (80,000 LY for NGC 2903 vs 100,000 LY for the Milky Way). I also recorded red, green and blue exposures on June 8 2018 and earlier. NGC 2903 is a face-on galaxy located 20.5 million LY from Earth and measures 12.6 x 6.6 arcminutes in angular width.
This is my second image of NGC 2903, a Spiral Galaxy in Leo.

This is my first image of NGC 2903, a Spiral Galaxy in Leo. I captured this luminance image with a C-11 SCT on April 21; I recorded 21 five minute luminance exposures on Apr 21 for a total of 105 minutes.
