The Baader zoom is known for it's great versatile performance with h-alpha. Unfortunately as many of you Lunt 50mm owners know, it does not reach focus with the scope due to a lack of in focus. I saw saguaro's post here: http://www.cloudynig...m-pt/?p=6476959 but the adapters would set me back $40+.  I went ahead and ordered a shorter eyepiece holder for the blocking filter- one that is 15mm tall vs the 30mm height of the original. Made sure to get one with setscrews to protect my eyepiece barrels from scratches. 

 

Arrived from China surprisingly fast- 9 days from the day I ordered.

Original on left, new one on right.

 

Height difference. Original on left again.

Attached to blocking filter. Original configuration seen first.

Zoom in blocking filter. Notice the small gap. It's caused by the eyepiece barrel resting on the blocking filter. Not by any means a bad thing.

 

 

Proof it reaches focus. There's still some extra in travel left.

Nice solution!  Thanks for sharing it with us.

The Lunt 50 must be the only HA scope that won't achieve focus with the Hype zoom (ls 35 ?) but a very nice

fix indeed.

Good to know, as I have that shorty eyepiece adapter..just no Baader zoom. :-( I'd been using my Lunt Zoom almost exclusively, than put a Meade 6.7 UWA in there and having a hard time going back. Large full disk in the sweet spot with room to spare. I did just order some optical adapters so I can Binoview with the LS50. Let you all know how that goes...

What binoviewer do you plan to use with it?

I have a WO with a couple of matching barlows. If it works out I'll be even more pleased with the little Lunt.

I have a WO binoviewer as well. I'll definitely be looking forward to your solution.
