Re: Thermal Acclimation of My Lunt50

Makes sense. This is why the etalon is flopping around...

Re: Solarflats in Photoshop?

Use a female t2 thread ring - take the nosepiece off the diagonal and use the female ring to connect the diagonal directly to the back of the helical. That will save you valuable focus.

Re: Messing With a Sodium Quark - 22nd May

Thanks guys, it is quite a subtle difference from the white light Ewan, both visually and on screen, i'm hoping that larger apertures show the structure better.

No flat Valery, you can see the dust bunnies if you look carefully in the same place on both images. It has a very well illuminated and even fov.

Re: Messing With a Sodium Quark - 22nd May

Thanks Stu! Might be a while before there's a big spot again, but will certainly be fun playing around with the larger apertures.

Re: Thermal Acclimation of My Lunt50

I got the lens spanner out last night and tightened down the cell on the ERF, so will see if that helps.

Messing With a Sodium Quark - 22nd May

I decided to take the plunge and get a sodium quark; i've only had it since the start of the week but are pleased so far. The image is bright visually and i'm getting short exposure time. I haven't had much time to play around with the tuner, but doesn't seem to be much of a variance in view either ...

Re: Thermal Acclimation of My Lunt50

The more I experiment with this scope the more i'm convinced the etalon sits loose in the chamber it is housed in. You can definitely hear a 'moving part' in the etalon chamber and it can only be the etalon. The fact I can get the sweetspot as a band implies the etalon is tilted relative to the norm...
