My Skywatcher mother board blew up several months ago, so I tracked the comet manually.
The DeepskyStacker you mentioned for comet stacking is that the same as Sharpcap Live view?
and presumably that would also failed to stack due to lack of target stars.

Re: Comet NEOWISE
How does your telescope track the comet? My skywatcher only has two tracking options: planets or deep sky objects, I cannot see how you can track the comet.

Re: Dark universe swamped by colured pixels
Thanks Dave, yes I spotted my darks/lights mismatch and I was hoping to fix this similar to what you have suggested but then the slewing problem popped up. I agree a dodgy power source could result in problems with both slewing motors, however I have a trusted mains based power supply - Maplin XM21X...

Re: Dark universe swamped by colured pixels
Robin, diy cooling fan is not for me. However, I am puzzled: I only made one attempt at imaging before and that was about 3 years ago with the same camera, I tried to image M31. Even though I had problems with my Live stack imaging I did not see any swamping of coloured pixels (as mentioned above)? ...

Re: Dark universe swamped by colured pixels
Yes exactly what I got, yes I would love a cooled camera but I will have to carry on dreaming and do the best I can with the 120. As you say the
problems get worse over the warm summer nights but I do not like staying up late and restrict my viewing accordingly.

Re: Dark universe swamped by colured pixels
All good tips Dave - Thanks. I certainly will take dark frames before I begin stacking again - not for a few weeks though. What I like about Sharpcap Live stacking is even though I run unguided it gives me good results especially as I do not wish to do any post processing.... Take care and happy sta...

Re: Dark universe swamped by colured pixels
Thanks Dave, I knew dark frame subtraction would improve the image but thought it was not essential, however if you look at my image then you would have to say it is totally essential, is this because the uncooled asi120 camera? Also when you start stacking would you expect the dark correction to be...

Dark universe swamped by colured pixels
Skywatcher Startravel 150 refractor and asi120 coloured camera. Mount Skywatcher EQ-6. Live stacked M51 with 32secs exp, gain 82%, 37 frames stacked but no dark frame subtraction. No filters fitted and used Bahtinov mask for focusing. I expected loads of hot pixels from my camera but was taken aback...

Frame exposure time to short
In both Sharpcap 3.14 and 3.04. Camera ZWO 120 MC - USB 2.0 Think Pad Laptop running windows 7. After closing Sharpcap and re-starting several times the frame time gets corrupted. No matter what exposure time I set the frame gets wrongly terminated after about 1 sec. It stays like this permanently. ...
