Got my new scope too late to see our galactic neighbor.

Pleiades, Subaru, Seven Sisters

Celestron AstroMaster 114EQ
100 points

M45 was my first astrophotography object, piggybacked a Nikon D3200 with a 200mm lens to get this shot: M45 (Not the greatest shot I've ever taken)

Magnificent cluster for anyone with a small telescope(or large), how many stars can you count?

This single point of light hides a surprising 2 stars. A beautiful binary system.

Triangulum / Pinwheel Galaxy

Mead LX200 (Cabrillo Observatory)
30 points

People in astrophotography go galaxy crazy. It must be something about the scale of them. They defy logic and imagination so of course, they must be photographed. I agree.

The following photo was taken using Spock, the LX200 at Cabrillo University. The resulting image was then processed for color and sharpness.

Hercules Globular Cluster

Celestron AstroMaster 114EQ
30 points

Giant glob of stars! Stars here and there and everywhere! Wasn't the greatest night to view the sky but I got to see the a great cluster.


Nikon D3200
50 points

Got to see this little point of blue light during the 2014 October Lunar Eclipse. Uranus Wasn't able to see it through the telescope since I was using it to watch the eclipse. Waiting to see it again when we swing around the sun once again later this year.

Ring Nebula

Celestron AstroMaster 114EQ
10 points

Took me a few nights to find this nebula. It has a nice visible ring shape,even in a small telescope. I wasn't able to see the star in the middle since my old telescope wasn't the best. Waiting for Lyra to come around again to view it in my Skyview Pro.

C/2014 E2 (Jacques)

Mead LX200 (Cabrillo Observatory)
1 points

This comet was shot at the Cabrillo College university as part of the Observational Astronomy course.

This was the first Comet I had ever observed, much less attempted to photograph. By September Jacques had already faded to Magnitude 11 but we decided to give it a shot anyway. After a bunch of processing the coma just shows up and the tail is visible if you use your imagination.

The poor quality of the shot didn't phase me, if anything it got me even more excited to attempt more astrophotogr...

Dumbbell Nebula

Celestron AstroMaster 114EQ
20 points

My first telescope was great at showing my first views of the night sky. My first DSO target was the Dumbbell nebula. It looked quite round compared to what I thought it would be. Colorless, almost featureless.
