As I await delivery of my EXOS2 is there a quick & dirty method to mount my DSLR to it?  Will probably attach nothing more than a 135mm lens and try rough PA with the included polar finder.
I ended up picking up a cheap dovetail plate, just to test if camera mounting would be of interest to me. Something like this:

https://www.amazon.com/Orion-7383-8-Inch-Dovetail-Mounting/dp/B0069WCOA2/ref=pd_bxgy_img_3/137-0671962-3157535?_encoding=UTF8&pd_rd_i=B0069WCOA2&pd_rd_r=3e1e2231-44c8-4dd2-9661-6123b5bdc4ee&pd_rd_w=mYU3e&pd_rd_wg=uzkNg&pf_rd_p=ce6c479b-ef53-49a6-845b-bbbf35c28dd3&pf_rd_r=0KG4N32V3ZQY4NMZ6JFT&psc=1&refRID=0KG4N32V3ZQY4NMZ6JFT

Then just buying a few 1/4" screws (#20 thread, I believe) + a few sizes of washers as spacers, to achieve the desired distance (given the length of the screw), and to create a small platform for the base of the camera to rest.

The key finding for me in practice was immediate dew buildup on the lens of my camera. I was attempting wide angle astrophotgraphy, and my typical long dewshields for my telescopes restrict the field of view for wide angle lenses (i.e. regular 35mm lenses of a DSLR). Likely I will need to invest in dew heaters for the lens to solve this. Just something to keep in mind!
