Hi, yes, I think the problem was that with SharpCap having dark correction activated, the statistical removal of hot pixels was based purely on the dark frame (it's easier in the dark frame - no stars to worry about). That's fine on the assumption that the hot pixels remain pretty constant and has w...

Hi Mike, the first place to start would be to take a look at this if you haven't : https://docs.sharpcap.co.uk/4.1/#I%20get%20the%20wrong%20results%20%E2%80%93%20SharpCap%20says%20my%20Polar%20Alignment%20is%20great%20after%20adjustment%2C%20but%20it%20isn%E2%80%99t! Any flex as you rotate the mount...

Hi John, I am guessing you have this setup : https://rowanengineering.com/products/a20631200a From the instructions it looks like it will accept LX200 data over the network, as you suggested. In theory, that would allow someone to write an ASCOM driver for it by taking an existing LX200 driver and s...

Hi, ouch, that sounds like a tricky one to solve... There are plenty of ASCOM drivers out there for the Meade protocol, but they all assume that they will be talking to a serial port (or perhaps a USB one) rather than communicating over WIFI. Can you confirm what device you have that controls your m...

Hi,

no problem - SharpCap has no way to find out which filter the camera is on, so it has to put it to a known filter (zero) and then keep track of the movements. However, if there are no filters then no need to do that!

cheers,

Hi, there was a recent thread on here about problems with darker pixels in the stack caused by a rogue hot pixel in the darks - just in one dark was enough to boost the average pixel value at that point and then the brighter pixel in the dark cut dark holes in the image. I have added a new option in...

Hi, thanks to Tim sending me a batch of images to test on, I can confirm that in his case, the issue is hot pixels in the light frames that are not present in the dark frames. For instance, there is a pixel at x=1504, y=964 with values in the region of 7000 in each of the light frames. The surroundi...

Hi Mike,

glad to hear that it worked! Now all you need is some clear skies!

Hi, I had a look at the focus graphs recorded in your log. In most cases the problem seemed to be that the scan was starting too close to the point of best focus, so that there were only a small number (2 or 3) points being measured before best focus is reached. SharpCap is looking for (ideally) thr...

Hi Trev, it's supposed to keep the existing plate solver when you upgrade as long as the selected one is actually installed on the machine. If you upgrade and have ansvr selected before the upgrade, but ansvr isn't there, it's supposed to change to SharpSolve. Maybe that's not quite working right al...
