I did my preliminary tests last night on the GSO RC 8". Several things need attention to make this OTA perform at its best.

I am awaiting a feather touch focusor and adapter. This will ensure rigidity.

Next this image is totally unguided. I am awaiting vixen guide rings from ADM. Guiding will reduce the star bloat and increase the sharpness of the images.

Finally, I am looking for a RC flattener. RCOS sells them but not on their website. I guess I will need to speak to Peter Ward about this. I used a Tak Flattener for this image and it has caused some defects in the stars.

However, this image does give me promise. It looks reasonably sharp with plenty of good contrast. This image is comprised of 120 second subs at ISO800. Flats applied, darks and biases.

Feel free to comment on this. It is not one of my better images but I put it up for a bit of analysis.
