Although I use a totally different setup I've found the longer I stretch out the exposure length the higher the reject list.

Having started to read your shared document, lots there, I see you have mentioned a virtuoso gti in there I am using a virtuoso v1 with synscan wifi dongle and have sharpcap/ascom/astap/phd2/platesolving playing together but in ascom the tracking rates option of RA or Dec offset rate is not enabled. I am curious to know please with your dob in ascom  is this feature enabled and the send to telescope button active? 

Definitely try things as you've done. You can also platesolve with ASTAP and sharpcap I use the pro flavour and ASCOM knits it together for me with a synscan dongle in my dob

If it's just planetary then with practice members have imaged by manually tracking the planet as it's very fast framed videos like exposure measured in milli seconds as the planet drifts through the field of view between adjusting where the telescope points, sounds very hard to me.

that's quite a light spill

Have you started first with installing the ZWO ASI driver.

nicely captured the comet, great green colour

Has the mount got the latest firmware and motor controller installs

You could take the telescope tube off and mount that on a suitable tripod. 

This thread shows the smaller 130p on a tripod, your tube is bigger though.

There is a mistake in what I wrote above re siril, I've corrected my original post

I had found it mentioned online somewhere re DSS and gave it a go. DSS with my data does better on comet and stars option. I also marked all 307 frames and not seeing a big difference compared to the three frames comet marked. I do choose a reference frame with the clearest space on the comet head as I think it might help with processing later.

What i did, once registered and whittled any poor frames out and date/time sorted the list I select the first frame and it opens. On the right panel on the image select the green comet icon. Using mouse wheel  zoom in and pick the comet head (the comet shows enough I can pick it out (use shift key if need to free move the mouse)) a purple circle marks the comet, select save. Repeat for the last frame and then do the same for the frame being used as the reference frame. I chose a reference frame around the middle of the list with clear starless space around the comet head. With my camera flats work best anything else gets noisier for me. Sigma clipping on the lights and comet and stars for the comet stacking mode. 

I'm not happy yet with my processing but I'm working with challenging data as I'm using an altaz mount and a noisy camera.

There's been lots of great comet images shared using different processing methods.

No, On Siril you just need to mark on 1st and last frame

Thanks for spotting this, and also the reference frame can be tagged in SIRIL

DSS after registering mark the comet on the first and last frame and the reference frame. (Siril similar)

ASTAP you have to mark the comet on all frames

I would with sharpcap point out window during the day at very distant tree (not sun) would be my thought. I would find the display easier to tweak what I'm seeing then when it's dark you won't be far off star sharp.

If you look at a star and focus it so it is as tight as you can then swing to Jupiter then the same eyepiece will be focused.

If there's bad seeing, transparency or  Jupiter is very low in sky then Jupiter might not resolve well.

There's a great flare in the comet tail captured.

welcome, great to read you are enjoying your telescope

I've not seen the mount base disassembled

that's a super comet capture and process.

Thank you for sharing what you did.  

Looks like I'll have to starnet++ to my tool base

Though ASTAP is great I am not looking forward to comet registration on 300 lights.

I too noticed this but I also also got a comet + stars stack out of DSS that has colour on both, this has made wonder how I managed this

That's a super image.

I used ASTAP and had a great circular star trail image but I wanted to stack on the comet and the stars.

Sounds good.

Has this improved your exposure length for your EAA?

The wider a lens is open the more evident any imperfections will show, having the lens not fully open often helps the star shapes. If you don't like defraction spikes on bright stars from stopping down you can either use step rings or make a cardboard aperture mask to stop a lens down which is what I've done for a lens I use which needs stopping down (the actual lens under the mask is on the widest aperture).

Orion is quite South now in the northern hemisphere means star trails show faster. East and West are more forgiving below 60 degrees for static photos

Focus is key. You could make what is called a Y mask out of cardboard to help focus on say Rigel good bright star in the area of your target.

Maybe focus in the daytime on a really distant chimney or tree (no where near the Sun) then you'd be close for the stars.

When stacking kappa sigma clipping can help tighten stars up. Be encouraged you captured Orion and successfully stacked your images. 

Focusing on a star will be easier and it will mean the nebula is also in focus.
