A couple of months ago I finally decided to buy Pempro to sort out the PE on the PMX and PME. Many people I know have used this programme for all the tools it has, but I just wanted to see if it could actually do PEC better than the SkyX.
Well I now know that SkyX for its PEC is just plain garbage. I had done it correctly according to their manual and applied the curve correctly but it never seemed to make any real difference to the guiding. This is what made me look again at Pempro. And; since I had installed Prempro before and had failed to take advantage of the free trial I decided it was time to buy.
Well last night I finally stopped procrastinating and go into sorting things out. All done remotely from home. I set up the run, got underway and did 8 worm cycles with a PE of 1.9" uncorrected. I then installed the new curve after analysis and did the test again. This time the PE was 0.9". So I then did some test guiding and the RA guiding could now sustain 2" sub exposures on the guiding and with some final tweaks to the guide parameters I was getting a nice flat guide graph in RA. Dec has always been great.
With that I set up a run on my next target in the RC and I began imaging at 12pm. I went to bed and woke up this morning with some of the roundest and sharpest looking stars I have seen from this scope. I am very happy I must say, and this is just another step in the tuning of this system. I wonder how much sharper my images will be now?
