An STL11 won't work on a 2.7 inch Tak focuser. It will vignette. Been there done that. Only 4 inch focuser works with STL11 sized sensors and beyond.
The larger field of view you get with an STL11 does suit many objects but I personally feel the smaller pixels of the 8300 are a better match for the TOA130 than the larger pixels of the STL11. Is not a huge difference
but you can see it in the images sometimes where the image tends to sparkle a tad more with the smaller pixels. These suit these shorter focal length refractors given average seeing. STL11 gives a nice broad field of view.
Also off axis guiding is way superior to self guide. It is not affected by filters. Self guide is handy at times though if you limit the images to LRGB.
But unless you upgrade to the 4 inch focuser all that is academic and you are limited to APS sized sensors (aqbout 24mm x 16mm), Beyond that you get vignettting and problems without the 4 inch focuser and flatteners.
So you have to add that to the cost to compare the 2 cameras.
