Hey guys! If you are looking for a cheaper Lunt50 focuser upgrade, here's my solution. The total cost of the project, around $200, but that depends on the cnc milling cost in your area. Typically, I pay around $10-15 for an adapter. Pre Diamond Baader Steeltrack 2'' focuser, was purchased from a fam...

Hello everyone. Since I have read the post https://www.cloudynights.com/topic/582337-should-i-sell-my-perfect-ls60tha-pt-for-custom-solar-scope/?p=7966901 , I'm really tempted with the idea of trying it out on my Lunt 50. Sadly, the poster did neither uploaded any photo proof, nor answered my privat...

Set my lunt onto the mount, focused onto the Sun with 20mm eyepiece. Unscrewed the ethalon with the diagonal and eyepiece from the scope. Put the refractor, with the focuser removed, onto the mount instead. Held the ethalon in the hands and tried to get the Sun in focus. Thought I nailed it pretty a...

Got this Chineese 80mm refractor from Aliexpress, which apparently has good optics, but the rest is so so.. Almost a perfect candidate , for the Lunt 50 ethalon, so I did that. http://i.imgur.com/h2JTQUj.jpg http://i.imgur.com/3lIOeNz.jpg http://i.imgur.com/6A9KOYC.jpg http://i.imgur.com/FLBk56l.jpg...

It's much darker, compared to DS-ing my Lunt50 scope with the Quark (using a celestron diagonal, instead of Lunt), using the same magnification.

My Quarks barlow was easy to remove, without damaging anything. You can screw on the Powermate 2x, instead and upgrade the blocking filter to 25mm from Andover . The native bf filter is Andover's 12.5mm. As for the F/30 focal ratio, it's probably overrated, Daystar claims similar performance from 15...

I have tried using the Lunt's BF600 diagonal on my 80mm f/7.5 refractor, Today. Unscrewed the Quark's bf filter from the barlow module, not to have 2 bf filters in row. Good news, the contrast of the chromosphere has improved a lot, much closer image to DS. Bad news, the image is a lot darker. The p...

I know, it's an old post, but, will give it a chance..
Is the filter still for sale?

Quarks telecentric assembly unscrews along with the blocking filter, so, if I use the Powermate 4x, that will eleminate Quark's blocking filter as well. The plan is to use Lunt's diagonal, with the Quark inserted in to the eyepiecepart of it. I will also need some sort of 2'' to 1.25'' adapter, sinc...

Hey guys, I'm currently searching for the solution to my Quark's rusted barlow, to be used on my Lunt 50 with BF600 diagonal One of the options, is getting x4 Powermate, which supposedly simply screws onto the Quark, once it's native filter/telecentric part is removed. Since the BF filter is also re...

Thanks. Now it's pretty obvious, that Daystar not interested in sending the replacement telecentric lens. Are the any cheaper alternatives to the x4 Powermate, I can possibly use instead? Also, If I replace the telecentric lens wit the Powermate or any alternatives, can I possibly use my Lunt's BF60...

Thank you.
25mm filter sounds tempting, but, I'm strictly visual and don't do imaging, so not sure, if it is worth spending extra on it, or is it?
Can Quark's own BF filter be reused with the x4 Powermate, if so, will it require an adapter?

Thanks man, guess x4 powermate is the only option now.
Question is, once you screw in the powermate, instead of the Quark's telecentric, what about the blocking filter?

Hi Alex, I had to replace the Quark telecentric with the 2" 4xPowerMate after the small negative lens broke (probably due to a too much tight retaining ring). If you unscrew the telecentric from the Quark body, you can screw the PowerMate to the 2" nose-piece thread, which is identical to the 4xPow...

I doublestacked my Lunt 50 with the Daystar Quark, the difference in chromosphere details is phenomenal. It's not only about the contrast improvement, but the image becomes a lot more 3 dimensional. Sadly, the barlow of my Quark happened to be "dirty" and I get a lot of dust on the image, which I'm ...

Mechanical pump of some sort, is probaly a better solution after all.
No need for the power, no noise.
Just need to find a portable one of a good precision and not overly expensive

Can certainly be done. Lunt doesn't need that much pressure, there was info posted somewhere, around (if I remember correctly) 20psi all it needs. A bottle of coke has more pressure than that. There's a thread, where someone modifies an etalon to a vacuum tuned, but, an expensive precision pump was ...

Thanks mate,
Waiting on the Daystar's response, before trying anything else.

Guys, as it happens, my Quark's barlow lens is pretty bad, with a large scratch on it and multiple other spots of unknown nature. http://i.imgur.com/ryJo5UG.jpg Whe used alone, Quark doesn't have any visible issues. But, doublestacked on Lunt scope, I can see multiple particles, covering the whole p...

Thanks man, I will think about ordering a 40mm piece as well.
Was under the impression, since F/5 has a smaller magnification factor, 32mm should work similar to 40mm on the slower refractors.
Have you tried stopping your scope down, to say 70-80mm, to get closer to the recommended F/30?

I was just checking some cheaper plossls (SPL) on aliexpress, which seems to have very good reviews since I want to know first, which size I prefer the most. Later, when I know for sure, I will get a premium piece. Since I'm planning to use the Quark on my F/5 102 refractor, as well, I decided on 32...

Is it easy to remove the 4.3x telecentric +blocking filter? I tried the Quark on my Lunt50 Today, but had to remove the Lunt's B600 Diagonal, since the Quark already has the blocking filter. The visual image was phenomenal, but since I used the Lunt's zoom eyepiece, it was pretty dark, due to Quarks...
