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...

Re: Lunt LS50+Visionking 80mm/F7.5 MOD And Questions...

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...

Re: My observation on Quark with Lunt BF600 diagonal

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.

Re: Need a full disc HA sidekick (PST/Quark/??)

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...

My observation on Quark with Lunt BF600 diagonal

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...

Re: Quark Chromosphere + Lunt's BF 600

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.

Re: Lunt50+Daystar Quark as doublestack?

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?

Re: Quark > Optical Design > Detail available?

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...

Re: To Double stack, or not to Double stack

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 ...

Re: Lunt PT mod- vibration dampening

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 ...

Re: Lunt50+Daystar Quark as doublestack?

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?
