Hi Robert
I just purchased a JMI SCT motofocus from Striker (thanks Tony!) and last night was the first night I used it. It replaced my refractor JMI that I had modified and the new one is more responsive. All my successes with sharp focus are due to the motorised focuser.
Last night, the Moon was close to Jupiter so I achieved a sharp focus on the Moon and then locked my Hutech SCT focus lock knob and slewed to Jupiter.
Part way through the evening, the image began to look soft so I went back to the Moon but the seeing was quite bad so I returned to Jupiter and picked up one of the Galilean moons and spent about 5 mins tweaking the focus using the JMI.
I also made a small tweak of Bob's knobs to touch up collimation. For a short while, there was a period of very steady seeing, probably lasted for maybe 20 to 30 mins in bursts, before turning mushy again.
The only processing is Wavelets 1=30, 2=20 and the rest remain at 1. I've punched about 30 AVI's through Registax so far, using both the lappy and the desktop. I keep sneaking out and setting them up to run, so I'm also having a social, family Easter!!!
To manage my tiredness, I doze on a camping mat outside by the 'scope, and these little cat naps, perhaps 5 or 10 minutes at a time, really seem to help me cope with the all nighters and the important family commitments the next day.
Cheers
Dennis
