Luckily my152/900 scope is close to lunt 50 f/d ration, so no barlow is needed!
I was also looking for a fully screw system.
here is the result :

As you can see I also take the opportunity to connect a jmi focus system far better than original one!
Always very useful to know, thanks!
Hello DSobserver I have a question:DSobserver wrote: ↑Sun Apr 09, 2017 2:52 pm After many years dealing with inconsistent Ha area with my PST mod, I decide to move to a lunt 50 mod.

Cool. I have save for a TS telescope I do need to buy it.DSobserver wrote: ↑Fri Oct 27, 2017 7:22 pm hello
TS scope is same as tecnosky one
lunt 50 mod is really easy it is a M68 screw same as the focuser from the scope! You'll immediatly get 95% of the mod.
Next if you want to change lunt focuser and get perfectly same distance between focus point and filter, you'll need some specific adapter.
I could comare visually this mod with 8" HAT : my "cheap" mod was impressive!
I'm sorry.marktownley wrote: ↑Fri Oct 27, 2017 8:46 pm Hmmm. M68 on the lunt 50. That does make things interesting in the mod department...

Very true Valery. I think I will give my lunt50 etalon unit on the back of the HaT, it should just screw on with the correct adaptor.
Which etalon did you mean? LS50FHa? or from the LS50THa ?marktownley wrote: ↑Thu Jun 21, 2018 9:47 pmVery true Valery. I think I will give my lunt50 etalon unit on the back of the HaT, it should just screw on with the correct adaptor.
Basically yes but all depends on what scope you are talking about!paulf wrote: ↑Thu Jun 21, 2018 8:48 pm Hi, new to the forum and solar imaging! I’ve got Lunt LS50THA with B600. Just checking I understand this thread, if I had a 152mm refractor then it is possible to remove the objective and tube from LS50, screw directly into the refractor focuser, install an ERF, and then I’m good to go? Or would there be other upgrades needed, like moving to B1200.
Thanks for reply, don’t have a refractor as yet, but just thinking ahead.DSobserver wrote: ↑Fri Jun 29, 2018 3:09 pmBasically yes but all depends on what scope you are talking about!paulf wrote: ↑Thu Jun 21, 2018 8:48 pm Hi, new to the forum and solar imaging!

Larger bf would be better
Prefer coronado 10 or 15
Hmm, interesting. Where does the image come from? I just double-checked my specimen (purchased in 2015) and it seems to have a doublet. I mean I didn't disassemble it, but it shows two upright minified reflections of my phone's LED when I hold it close, the same as my 90 mm achromat's objective.
Definitely! You will find some successful mods here on the forum. Mine are here and here.But I have been thinking to jump forward and get a Lunt 50 and then 'in the future - not now' possibly modify it
