Strange happenings with filter focus positions


#1

Hello again.

I am relatively new in this game with 4 years experience which I recognise is very little really. Along with very limited clear skies opporunity.

So every now and then I like to take another step. The current step was setting up the focus positions for my filters. I read the sgp help file shile it was daytime/ cloudy/ raining and I thought i had it sussed out. Here’s what happened though - am I doing something wrong?

My microtouch indicated 18253 for focus for the lum filter. So I opened the filter dialog from CP and entered that value. I then changed to R filter and ran autofocus again. It gave me 18246 so I put that into the dialog and closed it. Tried to change to green filter and run autofocus but It took ages to change. When I looked at the cp dialog it was moving the focus position - which is why it wouldn’t change I guess. It moved it to 60000 which is how shall I say ’ not anywhere near focus’

so I have had to scrap this as I am obviously doing something wrong.
any help appreciated.

Paul

Changing focus position when your filters are not parfocal is an all or nothing proposition. You cannot enter focus positions just for a couple chosen filters (I just added protection for “0” values). That said, I would expect SGPro to rack the focuser in so we would need to see logs.

In the 2.4.3 build you won’t need to (you still should though). If it finds a zero value, instead of moving a ludicrous distance like 18,000 steps because one of them was left at 0, it will do nothing.
