Those pics sure do help your cause
I especially like sombrero and M83.
I have a laptop and a canon 550D and t ring. and have used BYEOS for the free month (did some planetary hand tracking with an 8 inch dob ) will need to buy a full copy though.
Its a bit unfortunate you found the need to replace the focuser. in terms of adding to the price.
I like the ease of a refractor though, no big mirror to cool, no air currents in the tube, no collimation, no obstruction and spines, much easier to manage, just the price is aperture and errm money.
Currently a 6 inch newt is my fallback plan if I have to buy new.
