I modified the spider on my old 114mm to reduce diffraction spikes and it's actually quite a reasonable astrograph. Had to adjust mirror height a bit for focal length. Pretty easy.
The EQ mount is sitting in the garage gathering dust though. I had thought of using it for a widefeild camera mount where SCP alignment and tracking accuracy is not so critical. I added a motor to the RA drive so it actually doesn't do too bad. One rainy day I'll sort it out and give it a go.
