This type of thing has been done quite a bit by others here on Cloudy Nights, you can find many threads discussing C mount lens, security cam lens, and the like...
Here is a good example thread with a lot of information for those interested: https://www.cloudyni...r-rt224-camera/
Even 500mm mirror lens like this: https://www.amazon.c...duct/B004WLEEHI (kind of like a mini SCT)
Often the challenge with this approach is the quality of the lens, and aberrations from glass that really isn't designed for low light results. However, you can find some great C and C+ mounted security cam lens' that work fantastic for this sort of thing.
Also, consider simply using a common guide scope, like https://astronomy-im...minguider-scope
In fact, Orion's "Starshoot All In One" comes with an 8mm C-Lens intended to be used as an 'Electronic Finder', but works great for EAA coupled with their small finder scope.
The OP is using Sharpcap on a laptop, which is a great way to go, but you might also consider ASILive on a mini-stick, or something like Astroberry, or even ASIAIR to simply work with your tablet or phone. I've even used one of these to make an ultra small pocket portable EAA rig.
Also, this is a fantastic way to utilize an old Revolution Imager if you have one lying around.
Just hoping to inspire your own ideas
