Well, it's that time of year again and when you have a new set of NB filters and want to give them a test drive, why not trusty old M8?
I've solved the mechanical issues that were giving rise to collimation shift, but now have some tilt again... sigh. Good news is, you can't really see the tilt so much with so few/small stars!
I was also graced with some good seeing for some of this, which has been very rare this year... could certainly do with some more of that.
Big one here:
