Originally I had gone out to shoot a few pictures of the moon and while I was waiting I decided to see If i could catch anything from my light polluted backyard. Stumbled across M23 (took me about 15 minutes in stellarium to figure out what it was)

 

This is the second time I've photographed a cluster (first was the jolly roger cluster) . All I used was the Nikon D800 and the Sigma 150-600

 

Tech specs:

 

ISO - 5000

Exposure - 1 sec

Light Frames - 95

Dark Frames - 50

Bias Frames - 30

 

Picture of said moon also attached.

I was able to take another 100 shots of andromeda, this time I changed out the battery halfway through and helped with much of the noise. I ran through DSS with the other photos giving me a total of 4 minutes of exposure. (for comparison see above)

 

Below that about 1 minute of exposure on the Double Cluster X persei and H persei

 

And finally the Mars Moon conjunction from last night around 4AM

 

Shot with a Nikon D800 - Sigma 150-600 (no tracker or guidescope, just manually moving the tripod head)

 

Software used - DSS to stack and photoshop for stretching and light pollution removal.

Added more data, just for the heck of it and for the sake of practice

 

also to help me with star hopping and finding stuff in general. Also seems to be a great exercise when it comes to learning the pre and post processing portion.

 

I did this in pixinsight this time. First image was before I added more shots to the stack and the second is my most recent run of the data I have.

 

600mm

1sec exposure (still too much for 600 so the stars are not round)

5000 ISO

backyard with lots of light pollution.
