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 ...

Re: Local galaxies. big telescope versus small telescope

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

Re: Issues with short exposures and flats

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.

Re: Issues with short exposures and flats

Alejandro,

I'm not sure if it makes a difference, only because I am anal retentive about capturing everything in FITS, but I noticed that your Master Dark is a TIFF file and the others are FITS.

Re: Issues with short exposures and flats

Alejandro, My bad, I meant to say Smart Histogram. So you've got a fast scope and/or bright sky. So, if Smart Histogram recommended 15.6 seconds then that negates my concern. Sorry, I wish I could help but I am out of ideas. Except for one! I noticed that in the upper-left corner of your image you h...

Re: ASIAM5 Polar Align

Jerry, I'll only point it at the Sun when the Sun is below the horizon and I want to photograph it rising being a lighthouse, for example. I'll do the same for the Moon. It just shows the Sun and Moon, but I figured in your case you needed to verify that Polaris is where you hope it is. Do that by c...

Re: Issues with short exposures and flats

Hi Alejandro, I am replying based on my experience with "short" exposures. What is short? It's all relative. What's short for me is long for the next person depending on sky brightness, camera, and scope. What does your sensor analysis say? Mine says 60 seconds so I know I'll have trouble ...

Re: ASIAM5 Polar Align

Jerry, If you have a smartphone (I have an iPhone 12) go to the App Store and search for "ephemeris". The app you are looking for is "Ephemeris: Moon and Sun Seeker" by Vito Technology. It uses the phone's built-in hardware to tell where the Sun and Moon are in real-time. It uses...
