Re: eclipse settings

Hi Wayne, You list your location as "Bolton Laning" (sp?) Would that be the same as Bolton Landing? According to astrospheric.com you are just south of the path of totality. They say you will get 99.51% of the Sun obscured. What source are you using? I'm driving from Peekskill (40mi north ...

Re: M42 chronicles

Dave,

Yes, too short of an exposure brings its own set of problems. I think you are good with 3 stacks: 30s, 60s, and 120s. Then just concentrate on reducing noise by increasing Integration Time like 50x30s, 50x60s, and 50x120s.

Re: M42 chronicles

Hi Dave, Thanks for the great write-up! I have a question. Let me repeat your Lights exposure times. You wrote: Data: Lights 50x10s, 30x30s, 30x60s, 15x120s When I convert to Integration Time, I get: Data: Lights 500s, 900s, 1800s, 1800s IMO, you won't gain much faint nebula by moving up to 240s exp...

Glen,

If you have Google Drive or something similar, create a folder and make it public. Upload your image file there, then send us the link to the folder.

Re: ZWO 2600mc pro problems!

Hi, Everyone brings up good points. I suspect that it is power related. Try replacing the battery pack with a power supply that plugs into the mains, just for testing. I've got an old Atik 314E that requires a regulated 12VDC supply. I run it from a battery but I also use a 12V buck/boost regulator ...

My vote goes to the VX24 (sarc off).
Great work, Tim!

Alejandro,

Sorry, Dave just informed that I was looking at the Focuser Temperature. Never mind.

Re: Issues with short exposures and flats

Alejandro,

Also something to watch for is cooler temperature. Your Lights were taken at 8 degrees Celsius but your Darks were taken at 0.1. Did you capture the Lights and Darks in the same session? It looks to me like you may have used the Darks from a library that you captured some time ago.
