Pst or Lunt 50

[MalcolmM]

I can't help with the comparison but would say I have been very pleased with my Lunt 50. Proms particularly are shown very well and there's also lots of surface features and detail. 

The scope feels chunky and very well made, the pressure tuner particularly has a very solid feel to it.

The focuser is not the best but I  find it adequate! It actually gives very fine focus control. I had a problem with my focuser after 6 months or so of use; the whole draw tube started to rotate slightly but @FLO very kindly replaced it for me with no quibble.

A 'must have' accessory is the Tele Vue Sol Searcher. It makes finding the sun a doddle!

Lunt ha scopes come with a searcher as part of the package, when it comes to viewing / positioning the sun there is no alternative. I have had my Lunt 50 for a couple of months, replacing my 40 but the temps have been too low that I haven't had a chance to try it, lol. I ordered the Moonlight focuser for it and the case but they are on a few months backorder.

Hello, 

I've the Lunt 40 b600, really a great solar scope, comparatively with a PSt, very old and a good Lunt 50 b400, I like more the Lunt 40 image, in visual mode, why? 

I Don't Know!! 

All above is my humble and personal opinión!! 

Thanks, 

Tico

I just sold my Lunt 40 as I mention above but the scope is a great well built scope, with excellent, detailed views, you just have to remember to pull the diagonal out about 1/2" to gain perfect focus, thats a common given.

Sometimes I have the feeling that (generally)  some 40 and 50 Lunt's show better prominences then some Lunt 60 , while the SD is generally better in the 60. (It's like that there are some advances and disadvantages beteen all units or bunch to bunch)  And then... better seeings helps too "solve" this, but less common. I am happy with my Lunt, am using up to 60x with zoom. But it's quite clear that the surface detail makes a better impression generally.

There has always been some slight discrepencies in the etalon, they are not easy to build and get a consistant lens / filter, thats why they are so costly.  The 3 ha scopes that I have owned have all been great performers. And as always air currents, heat rising always affects view quality, hour to hour, sometimes a lot.

Okey.....differences seems very normal in solar telescope due to complexity and small deviations in the production.  I thought once that it had to do how bright the scope is or how ALL filters in the system works together. Yea...seeing can effect every telescope in their own ways

With my WL filters / scopes many times I either use a Variable Polarizing filter or a #56-58 green filter, they can really enhance the views.  I tried the variable filter one time in my ha scope but it made the view way too dark.

Hi, maybe there are ways to improve your scope the way you want it: in single stack best is to use the scope how it is. In dual stack mode there are uV IR KG3 filters that are more then 2x brighter then the blue or the previous blue green BG filter. However, I have never heard a review ( only from a Lunt 40 scope) .  Maybe Another more effective way to improve your scope  is to use A DS filter with your blocking filter and a refractor with longer focal length, same aperture but without all the extra filters from your alpha h scope! Maybe I will try this once .
