Re: SharpCap Plate Solving/Celestron Evolution and Sky Safari

Hi Robin, Yes, that's pretty much the way I understand it. I am using SkySafari via Celestron Wifi to connect to the mount for alignment and gotos. This does not use the ASCOM driver and the alignment information is kept entirely within SkySafari. (I think it computes and stores an offset from the m...

SharpCap Plate Solving/Celestron Evolution and Sky Safari

Hi, I use Sky Safari 6 connected to my Celestron Evolution mount via WiFi for alignment and gotos. This has the unfortunate consequence that the mount does not have the correct position of where it is pointing for any given goto. Since SharpCap Pro uses the mount's position data via a USB cable conn...

Re: unguided galaxies

Is there something that can be done to remove the artifact at the bottom of the photo other than clipping the black level? That's a tough trade to have to make, and I can see why you did what you did in the first photo. By the way, I believe that outer space is indeed black. It is not gray. It is on...

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 ...
