ASI294MC What am I doing wrong !

Never use a gain of less than 120 on the ASI294mc pro as it alters how it reads the pixels.

Hi Adam,

 had this Camera for 6 months, tried the unity gain ( corresponding 120 s) in SGP. Result was extrem Col.noise and stars were kind of overexposed , RGB histogram by far misaligned .

In the course of time, turned down the gain to 70 and from 300s to 180s and the C.noise dramaticaly went down . This is purely my expeirence. I cant try this again as I sold off this cam.

 Was trying to combine the lum from CCD with CMOS OSC. In the end I gave up,  lol.

Adam , did you use this camera or did u check personaly how the gain values respond ? Curious 2 know, probably my handling was wrong. This was my low gain attempt HLRGB.

cheers

It went down because it automatically bins the pixels below gain 120.

Ah, interesting. my brain pixels too binned now.😜 manually. Humming teach ur children well.

Hi

I was playing with your data - hope you don't mind !, you have a very rich area of the sky which is full of Ha nebulosity.

I stacked your Flats, Darks and Lights in DSS, I can't believe how sensitive this camera is, I can't wait to get mine out !

I tried not to stretch it out too much, but wanting to retain as much of the surrounding nebulosity as possible and used some noise reduction.

How much is high, when using backyardeos, I used to set it at 3

My dither is set to 15 in APT. APT goes up to 90 but i think its worked on pulse length rather than a set distance. its pretty random which seems to work nicely. 

I ditched BYEOS for APT, cheaper and seems a little more flexible. Wouldnt be without pointcraft now either.
