As far as a larger scope recording more details, I would be very cautious. I'm not sure that this will be the case. As far as I am aware, more aperture will resolve stars better, but as far as detail im not so sure.

I think that the local seeing will play a greater role as well as the sampling of your setup, which may well be better for deconvolution with the RC8.
Hi Peter,

Thanks again , definitely more reading on my part required and appreciate the honesty before I make any jump . I have obviously miss-understood an article I read about aperture and resolution of details. I will look into the deconvolution side of things as I am not sure what that means (still a steep learning curve to go for me).

I still like the idea of an F4 over an F8 due to the light gathering capacity but as you rightly pointed out I can go 10+ minutes subs (tested at 20 minutes as a max without issue) at the moment without any real hassle on the gear I have so introducing flexure into my system would be a step backwards.

On to some more reading

Thanks again.

Anthony
