I mentioned this sometime ago, but it’s reared it’s head again.
One of my setups is with my 10” RC with an OAG,
I have just upgraded to Chroma 2” 3nm NB filters, i’ve already grabbed my LRGB in this instance of M51, I now want to grab some Ha to compliment it, however having been nicely in focus with my Pegasus UPB and focuser, it’s struggles to find a focus point, even though Chromas are supposed to be parfocal.
All of my focus steps have been calculated properly for my Lum, I’ve extended the focus duration for the Ha to 100secs, but it struggled to find focus and then racked my featherlite focuser so far out that it took my OAG so far out of focus that the guider could not settle, settings are set to settle at 1.5 arcsecs until I have sorted the problem out.
The issue is that the focus dialogue box will not let you cancel until the guider has settled, the guider won’t settle as it is so far racked out of focus, eventually I have to resort to ending the process and then reopening SGP. Surely by pressing the cancel button it should act as a kill function and shouldn’t have to wait to cancel the focusing until the guider has settled.
Any ideas how to get around this?
Thanks for your input.
