Re: Live Stacks January 5 and 6 2019

Thanks Wikkett. I may have to juggle some things, but I will try to tune in. Good luck with the weather forecast!

Re: Live Stacks January 5 and 6 2019

Fantastic images! I hope you don't mind answering some very basic questions about the Live Stacking technique you used. 1. Are you making any changes to the histogram settings (black, mid, and white levels) while the stack is building? 2. If so, when do you stop making such changes? 3. How do you de...

Re: M42 chronicles

Thanks Rob. I'm not looking for a camera, but maybe this will help others. The "camera" (Revolution Imager 2) I have is not billed as an astrocamera. It is an imager primarily meant for beginning EAA that came bundled with my telescope purchase (i.e., it was essentially free). It meets and exceeds i...

Re: M42 chronicles

This thread is more about the journey and to try to get over to beginners that my improvement is about mount alignment, polar alignment, focusing, checking the histogram of a single frame in FITs Liberator rather than equipment. But Dave, at the risk of coming off argumentative, which I am really n...

Re: In need of a SharpCap tutor

Nice shot! You're making progress! Unfortunately, our skies have not allowed me the chance to do any observing for quite some time. One of the limitations of a camera like ours in a long focal length telescope like we have is that yields a pretty small field of view. Notice that you cannot even get ...

Re: In need of a SharpCap tutor

The idea of Live Stack is to accumulate faint images and create a stack. The stack will give a better image than the single frame. If you can see the object with a single frame then using those settings for stacking will soon blow out the resultant image. This is where understanding the use of the ...

Re: In need of a SharpCap tutor

Joe, When Dave says he first captures a single RAW frame, that means a single frame of the object in RAW format. It is a little confusing if you don't know what a RAW format is because there is no selection in Sharpcap to select RAW. RAW here means an uncompressed unprocessed image file, which in Sh...

Re: In need of a SharpCap tutor

Joe, It definitely sounds like you're on the right track. I don't know what caused your connection issue, but I have been having some erratic connection issues at times. I think these are mostly caused by weight of the camera's remote control pulling on the cable. I try to keep the remote perched on...

Re: In need of a SharpCap tutor

Joe, I have the same camera and telescope as you and just a smidge more experience with it. The fact that you can get an image on the monitor, but not in Sharpcap is very interesting. I've hardly used the monitor, but in principle I would expect the video signal to provide the same image in Sharpcap...

Re: First time success... well, not quite. Need help

Joe, Have you had any luck in being able to image anything besides bright stars with your Revolution Imager and Sharpcap? I have the same telescope/imager as you (but without Starsense). The key items for me in achieving an image to start working with in Sharpcap (either preview or Live Stacking) ar...
