Re: I can't find a stacked image of M27 in my Fits Lib. File

Also: use SAVE AS VIEWED which produces an 8 or 16 bit PNG file There is no "SAVE AS VIEWED" in the current version of SharpCap. It is either "Save with Adjustments," which "will save the image with the Live Stacking adjustments applied (i.e. after histogram adjustments and colour adjustments have ...

Re: LiveStack histogram

Greg, I'm curious. Exactly what are you trying to improve about your image? From your display histogram, it looks like you could be clipping the black level. You may be able to regain some lost nebulosity by moving the black level slider slightly to the left. Of course, you may have already examined...

Re: 64 bit vs 32 bit

I've wondered about this as well. What would be the result of an out of memory error? Would it cause SharpCap to crash, or display some sort of error message? In other words, how would one know if an out of memory error occurred?

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 ...
