Re: Mosaic IC5070 Pelican Nebula

Yep, agree with all that. But I think you can do all the tweaking of color and stretching in the LS histogram (not touch the display histogram at all) and see the effects in the display histogram. (They won't be reflected correctly in the LS histogram since, as you say, that is using the raw data di...

Re: Mosaic IC5070 Pelican Nebula

I use the freeware GIMP for post processing. I'll have to see whether the PS features you use have cohorts in GIMP. I know most of them do, but I don't know about setting a threshold level for a gray point or whether there are tools like an HLVG filter or a Colormancer Boundary Noise Reduction Filte...

Re: Mosaic IC5070 Pelican Nebula

Really nice! How do you keep the star bloating down while stretching? Did you do all the stretching in SharpCap, or did you apply further stretched afterwards in Photoshop? (I'm curious as to what "cleanup" you typically do in Photoshop.) You are saving the images "Exactly As Seen" in SharpCap, righ...

Re: Seeing monitor capture

Yes, but my understanding is that's not using the seeing monitor feature of being able to filter the captured frames.

Seeing monitor capture

I haven't actually tried using this yet, but for one of the objects I would like to use it on (Jupiter), it would be helpful to have an additional capture length criterion. Since Jupiter rotates so rapidly, it is usually advisable to limit captures to one or two minutes in order to avoid rotational ...

Re: SharpCap Plate Solving/Celestron Evolution and Sky Safari

Hi Robin, The new Celestron PWI (CPWI) telescope control software appears to be the PC-based program that will get this to work, and it can all be done wirelessly. The CPWI program has its own mount driver that appears to talk to the Celestron ASCOM driver (at least, that is how I understand it). An...

Re: SharpCap Plate Solving/Celestron Evolution and Sky Safari

Please don't distract the discussion from what I am seeking. I am specifically seeking a way to use SharpCap's plate solving without using the handset for alignment. The SkySafari WiFi alignment is quicker, easier, and more accurate. I may switch from SkySafari to Celestron's new CPWI software, but ...

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...
