thanks i am using a very quick laptop the fps is probably due to my scope being in my obsy at the bottom of the garden and everything runs through usb over lan.maybe as you say i should increase my exposure time to decrease my gain ,i tended to keep it around 5/6 ms and adjust the gain to get about 70-80 0n the hystogram probably the wrong thing to do thanksRadon86 wrote: ↑Tue Aug 16, 2022 8:28 am Hi,
Your limb+proms .SER file was: Gain=247
Exposure=5.6260ms;; FPS=26
Your proms .SER file was: Gain=400
Exposure=5.6260ms;; FPS=13
I think the problem was: gain was too high. Exposure can be increased up to about 10ms or slightly more.
Your higher gain makes the images noisier.
Also: your FPS is slow.
Question:
What laptop are you using ? Processor ? and what hard disc. I think a fast SSD (NVME M2.SSD) is vital to get to the next level. I found this out. A slow hard disc cannot capture images fast enough. No matter how good your filter and setup work, you will not get the data you need.

Hi iwols,
Why not connect your camera directly to the laptop ? Any other connection will render it much less effective.

I had a play with the original SER file, stacked 128 and got this after a bit of mauling...

Hi,
I finally took a bit of time and here is my result processing your ser files in the same way I process my AVI files.
The prominence result is very noisy. as somebody already said crank down a bit your gain and increase a bit the exposure time.
I did not do anything in Photoshop and there is also too much noise.

Hi,
I did take a second chance on it and tweaked it a bit to my liking
The noise kills lot of detail.

Noise is certainly a detail killer. Right there, Rainer. I often have noise issues on single frame captures. Stacked images are better.
