Note to anyone interested in a zoom: the Hyperion is good: nice sharp images and not much dimming effect. What it ISN'T is parfocal - a lot of focusing is needed when you change mag. It's great for finding something at low mag and then zooming in without needing to change EP.

Update.

The non-parfocal bit is rubbish: please disregard. It was all my own fault.....the twisting force needed to change mag is greater than that on my helical focuser, so every time I wanted to change mag, I defocused. Stupid boy.....🥺

I now realise changing mag is a two-handed job.

Got myself a Baader Neodymium filter as a general-purpose anti- LP. I'm hoping it'll help with planets as well as improving contrast for M42 and suchlike. Of course, nothing but cloudy skies......

Now you're all going to tell me the BN is rubbish, right?
