A very interesting discussion as I am also considering a LS50 mod. I have few questions if someone would be so kind to answer:
1. I assume the mod is fully reversible that is I can have back the original LS50, am I correct ?
2. Is the red cylinder with the PT knob simply screwed to the LS 50 white tube ? can they be separated easily ?
3. Which M68 adapter would I need for attaching the LS50 rear part to the telescope ? has this part a male or a female thread ?
4. I have seen in the above image a Coronado BF replacing the Lunt diagonal, is this replacement necessary ?
Thanks in advance

Re: lunt 50 mod
After a long time, during which no one knew if the Lunt 50 had a lens with a single lens or an achromatic lens, I discovered from this image
that even the Lunt 50, like the Lunt 60., seems to have a objective with single lens, and therefore the use of the Etalon of the Lunt 50, together with the two lenses of its collimator, used on a new telescope with an big achromatic objective, will not allow to obtain, in h-alpha, all the quality of the new big achromatic lens ...

Re: lunt 50 mod
Hi
What an interesting discussion.
I am newbie on Solar and still deciding if to get a PST new [second hand is rare to find they go like cakes - obviously affordable!]
But I have been thinking to jump forward and get a Lunt 50 and then 'in the future - not now' possibly modify it to use on my AR152 988mm F/6.5.
What do you think - experts?
I am getting older and Solar would be an 'easy' addition for later years.
For now I am going to play a bit with White light only - just to get the hang of it again.
Thanks for your time
