Extension Tube for Baader Hyperion Zoom Eyepiece

[Gina]

Thinking of having a go at observing - particularly planetary - I tried my Baader Hyperion zoom eyepiece on my MN190.  Couldn't get focus - needed the eyepiece further out so I've designed and 3D printed an extension tube.  Here are some photos.

Very neat.

An off cut of random plastic pipe never quiet does the trick.

Looks very useful Gina ;-)

You probably already know but... if you type '100s' immediately after drawing your circle you get 100 sides (or however many you want) to get a smoother circle without the steps? OK, I thought you did ;-)

Yep - often do that   Didn't bother for this - thanks anyway

The extension tube fits - after a bit of filing down   Not had time to use it yet though.

Looks good Gina  The only thing is that you might find you get better contrast if you blacken the inside. It's surprising what a difference this can make with visual astronomy

Have to get some more matt black paint - spray can has run out.

Checked focussing range on distant tree and it's fine, so I'm all set up for observing tonight if clear as forecast

Had a brief chance to try it last night and it was just right   Just a few minutes before the clouds rolled in and stayed until I went to bed at about 11pm.  Weather forecast showed clear all night - ha flipping ha!!!
