I'm planning a bit of a change in my imaging setup and after much thought I need some input from others if you can.
I want to upgrade my setup, currently a SW 130pds HEQ5 with a 60mm guide scope imaging with a modded 500D.
I often find my imaging time limited but am planning the build of a mini obsy to make longer sessions more practical.
Would mounting a SW72 ed on top of the 130pds be over kill to get an dual imaging system going and increase the data volume, both with a canon 500d and a simple finder guider, the mount should be ok with this.
Or just keep the status quo and add an auto focuser for longer single scope sessions that can be more automated in keeping good focus with the lighter setup.
The dual version I believe would end up having wider field images as I would probably have to add the higher resolution from the longer FL to the shorter FL images.
Any 2p's worth would be appreciated I just want to achieve more productive sessions.
Here I have a quick session of NGC891. It was shot during multiple nights between targets, 1-2 hours each night. It consists of almost 6h of luminance and 40min each RGB. 120s subs.
I only shot 1/2 ROI so no larger FOV.
I think I could think of a larger and longer scope for this small targets.
I recently upgraded to ASI mono and my Canon left to collect the dust and I am not happy about it.
I spend a few hours around my scope thinking how to attach my Canon and start using it alongside ASI, which, currently will block any view from the dovetail.
I think to rotate the scope in the rings, so ASI and Guiding scope will be placed at the bottom and place Cannon on the top dovetail.
I am not sure if ASI or Guidescope will not hit the mount while slewing.... And not sure how to place Canon on the dovetail.
Has anyone tried such a set up with Newtonian?
If I will like the result, I think of Samyang lens for later...

Night of 12-13 June. I had not had a go at Saturn and Mars for some time, so set up the C8 to image them. Kit: Celestron C8 SE SLT, ASI120MC, ADC. Seeing: initially poor but improving through night.
The Jupiter images were unexceptional, but the Saturn ones resolve the Cassini division well (compared with my earlier efforts). The rings look odd - I wonder if this is the conjunction brightening I have read about?
Mars was very low when imaged at around 2am BST. I packed up because I was tired and cloud cover was forecast. I still got some surface detail.
