SharpCap Forums

So I've just had a realisation (which I haven't tried out yet) about a functionality in Sharpcap that can serve as an unguided dither! When I was dithering through PHD2 guiding, i would always select the spiral pattern over the random pattern (no other reason apart from the fact that I like spirals!...

That's exactly the idea, that it would help with noise in a sigma live stack. Also, unguided dithering on the mount via ASCOM should be (not a programming expert) easier to implement in comparison to guided dithering via a client like PHD2/metaguide.

That's really nice Dave, got that core and nebulosity with a nice balance! Keep it up and hope that our friend Robin gives us a dithering option soon

Hi Dave, My mount (AVX) can go upto 2 minutes unguided without giving me startrails using my Esprit 80 or even longer using my TSAPO60. I've lately stuck to taking 30 second exposures and then adjusting the gain according to the brightness/dimness of the target, sometimes I go 60 seconds and then ad...

Hi Robin, me again with more feature requests! I know it's been requested before (for integration with PHD2), but would it be possible in version 3.2 when you write the sequencer, to implement a checkbox for executing a random unguided ASCOM dither every #frames? This would be akin to what APT and S...

Thank you Robin, as long as it gets close enough to only require quick small adjustments, then that would be more suitable/quicker/efficient for doing EAA with my students.

Thanks and happy holidays!!

Hi Robin,

Would it be possible to have an auto white balance button next to the auto stretch button on the live stack histogram?

Many thanks and happy holidays!

Hello, Back when I was reading the literature and forums on how best to stack lights and darks in DSS, I came across suggestions about using the same stacking settings for both lights and darks e.g. median sigma-clipping. I've stuck with that over time and it seems to be producing nice results for m...

Thank you for that clarification Robin, much obliged.

Thank you Robin, very helpful indeed!

I'll try your suggestions and get back to you here if there is anything further!
