Re: Not uniform contrast with my Daystar Quark

From my perspective I'm amazed at the views Quarks can offer and I'm not a solid etalon fan but from what

I've seen its hard to imagine better views from a solid one (albeit the SE & PE range will be easier to use) , however my

preference is still to use a good air spaced one or two.

Re: PST ERF

Ah Right Thanks Ken

I hadn't realised that , that was the ITF ... I tried a UV/IR cut in the bf15 of the 60 yesterday (instead of the ITF) and did notice what I thought was a significant drop in contrast so reverted to the ITF ... but will try the PST DS with and without it.

PST ERF

Hi Folks I have been using a DS SM60 II recently and have been impressed with the views , but especially their ease and brightness !! this is obviously because the internal etalon is devoid of an ERF. This has me thinking that any DS system say 60mm and under would benefit from only utilising one ER...

Re: Mod TS 152/900 Individual

Yeah the Quarks have their BF in front ... Totally Weird imho !! but obviously works well and reflects most of the IR.

Is this not the PST Mod Holy Grail ... the DS Mod ... Respect if ever it was due.

Re: Double stack or refurbish my Daystar Quantum?

All depends, George. Not all etalons (or their stacks) work same nicely as, for example, your setup. I never was able to get a good result with double stacking of my two Quarks (with several other etalons). In the same time Mark Townley always reported that his stacking - Quark + PST work just fine...

Re: Coronado SM40 Etalon + Lunt B600?

I think I recall reading that Lunt BFs were compatible with Coronado etalons but that Coronado BFs were not compatible with Lunt etalons ... hope I've got that the right way round :) I doubt there would be much difference between a pre Meade and a newer SM 40 apart from perhaps their actual bandwidt...

Hello David
I have this adaptor (was for
an 80mm) that fits the Tmax tuner
I plan to send it to Mark at Moonraker along with a
dew shield for him to adapt ... is there

Re: Petzval refractors and Herschel Wedge

I normally only use a daft big achro with a wedge ... have used apos in the past but
never a petzval , imho the best white light views are obtained with a wedge prism and any refractor.

Re: Lunt 60 SS/DS or Lunt 80 SS/DS?

For me in Solar visually ... Bandwidth rules and not aperture ... Like everything it's
quality over quantity ... my preference would be toward pre Meade Coronado filters or even Solar-Scope if possible ... a Lunt 60 with an SM 60 should be great though.
