Re: Questions about Brain and when and when not to use it?

I use a gain of 121 with my ASI 294MC Pro camera and have never seen this banding issue.

Here's an example dark at gain 121: https://photos.app.goo.gl/dcqwnNptrufDwfKK7

Re: Livestack alignment settings

Hi, I think there are some good ideas here, and I share Chris' concern about retaining the ability to tweak individual parameters if any automated settings do not provide the expected or desired results. One item I would like to bring up is that alignment for stacking can be adversely affected by po...

Re: Making longer flat exposures with ASI294MC Pro: ADU or histogram?

I also have not had any problems with short exposure flats at gains from 121 to 250 for Live Stacking EAA in Bortle 6 skies with the 294 MC Pro. I use a varying brightness level depending on gain -- from 4 at 121 gain to 13 at 250 (and 23 if I use 300 gain). Flats are taken with a t-shirt wrapped ar...

Re: New Application for Live Stack in SharpCap 3.2

There are a good many of us that have been using SharpCap to practice EAA with ali-azimuth mounts for some time now.

Re: Imaging Jupiter: Lots of dots in my images

Nice work, Dave! I noticed you went a different direction from the tutorial you put up a while ago on capturing and processing an image of Jupiter. And the settings for the two versions you did here are quite different due to the use of the linked wavelets checkbox in the 2nd one. Do you have any cl...

Re: HOWTO Process Wind Affected Lunar Data

I found the solution that I needed if only a limited number of frames are affected. In AutoStakkert!, after doing the analyze frames, hit the enter key while at the frame you want to delete. This imparts a red coloring to the image size box. Select analyze again and the frame will be deleted from th...

Re: HOWTO Process Wind Affected Lunar Data

Hi Dave, Yes, I did find the document useful. I usually use the AutoStakkert framing sliders to initially set a smaller ROI to analyze and stack, partly to minimize framing issues caused either by wind or imperfect tracking and partly to speed up the stacking process. Even then, I sometimes still en...

Re: Recent change in "Target Name" field behavior

Hi Robin, We're not talking about renaming existing files. We're talking about entering or changing the target folder while live stacking and before saving the stack. The way it used to work for all the versions of SharpCap I've ever used up to fairly recently is that you could do this (as long as y...
