Re: Dropped frames ASI 294MC Pro

Disbelieving, eh? :) Well, ok. Turning USB power saving off thru device manager has been valid and around since powered USB devices first became available :-) :-)

Re: Dropped frames ASI 294MC Pro

Thanks Dave. Your first post of the USB troubleshooting thread contains a link to a web page showing "How to disable Windows 10's 'USB selective suspend' setting." However, this does not apply to the laptop I am using to run SharpCap. Although it is running Windows 10 there is no "USB settings" sele...

Re: Dropped frames ASI 294MC Pro

Hi Robin, Thanks for your usual quick response. I noticed the same thing, which surprised me since it is a USB3 connection. I wish I could easily replicate the issue, but it seems to be occurring well into an imaging session (i.e., time-oriented rather than any specific action or setting if that mak...

Dropped frames ASI 294MC Pro

I've begun to have severe issues with dropped frames with my ZWO ASI 294MC Pro/SharpCap combo. I am using the most recent (just posted) version of the 64-bit SharpCap at RAW 16 on USB3 with a brand new Windows 10 Dell laptop.As an example of what has started happening the last few nights, I started ...

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...
