That means a 2x Barlow set to give a bit extra magnification would allow you to run your frames at around 15ms.
Thank you very much for the advice Stefan. I suspected that might have been the case. Will certainly try that the next opportunity.

I have tried a couple of times with the same camera and 5x barlow on my 180mm mak cass at 14000mm with without any success, the frame rate is just to slow. I agree with the 2x barlow being the max. I find that keeping the wavelet adjustment to a minimum works best, if the data is good you shouldn't need too much processing to start of with.
Thank you very much for the nice feedback and advice Rick. Really appreciate it.
