Re: ASI2600MC To take Darks / Dark Flats or Not

Things move on though so what may have been the norm previously develops as technology software and other things increase, the CCD / CMOS long exposure debate being one of those things. As I have the tool available to carry out a measurement and suggestions from the brain on a condition by condition...

Re: ASI2600MC To take Darks / Dark Flats or Not

Brian, But surely the whole purpose of the brain in smart histogram is to make this decision in an informed manner using the readings it is seeing on that night at that point in time for the elevation I am planning to image. I do not see how one or two readings can be an adequate suits all situation...

Re: ASI2600MC To take Darks / Dark Flats or Not

Hi Dave,
My whole plan is that I do not want to have to shoot darks at all as they will be different every time I use the Brain option in the smart histogram.

Cheers

Re: ASI2600MC To take Darks / Dark Flats or Not

Right been doing some testing using the Horsehead and Flame image from the other day that I posted in the gallery. The comparison images below are all processed through APP today with the exact same settings and are the integration result at the point that the integration first completes so no furth...

Re: ASI2600MC To take Darks / Dark Flats or Not

Hi Dave / Pete, My intention was to shoot Flats as they not only correct for dust mites but also for any illumination discrepancies in the scope / cell so they will always be a requirement. As Dave has stated I think I will run the same data with and without Darks / Dark flats to do a direct compari...

ASI2600MC To take Darks / Dark Flats or Not

Hi, Just throwing this out there for discussion thoughts, I have the ASI2600MC and the sensor amp glow, etc is for all intents and purposes non existent in the histogram for exposures I have looked at 15s - 600s darks the mean figures are around 100 so negligible. The reason behind the question is t...

Re: Horsehead and Flame Nebula ASI2600C

Hi Brian, Thanks for the comments I will have another play with the images to see what else I can bring out and I don't mind people giving me suggestions / constructive critique as how else are we going to improve or learn. Just wish you could suggest something to do about the weather as the last fo...
