Solarmax 40 and Baader H Alpha 35mm CCD filter
Morning all, Just after some advice re the use of this filter in a Solarmax 40mm. As the erf in the diagonal has rusted its now been removed, and I'm intending to use the H Alpha filter behind the internal objective (see photos) is there anything else I need to be aware of? I have flipped the filter...

Re: Daystar DS 60
The led in the unit still changes to green in all settings but as the objective is bust I'm unable to confirm if the etalon still works. A visual look shows no problems and its not decontacted.
The lower Andover 656FS02-12.5 is also ok.

Re: Daystar DS 60
Yes it's out of warranty and the subject of a house insurance claim due to a broken objective.

Quark - condensation on lens
Hi
I have an old ish Quark prom and it suffers from condensation on the outside of lens immediately after the etalon, is this an easy fix.
Even if I store in in desiccant it still appears after a bit of use.
Thanks

Replacement Quark ERF
Hi,
Recently bought a quark prom second hand, its got a lot of problems (4 in total) but the worst turned out to be a failed ERF.
Anyone got a solution to this?
No idea of the age I'm afraid.
Regards Nigel

F11 PST scope
Hi
I have a Vixen 80mm f11 scope which I would like to use for a PST mod, as it is not the recommended F10 what differences in view can I expect?

Re: PST stage 1 can I remove the black box ERF
Thanks Mark, must admit I'm a bit confused as I was going to keep the black box (i.e. stage 1) and just remove the erf which is currently under the BF i.e. Current 75mm D-ERF - etalon - original rusty erf - BF5 Proposed 75mm D-ERF - etalon - (optional ir/uv cut filter?) - BF5 Not sure if I'm being a...

PST stage 1 can I remove the black box ERF
Hi On my TAL 100 PST stage 1 I have fitted an internal 75mm D-ERF, does this mean that I can remove the existing black box ERF which is located just below the BF? The reason - mine looks like it is failing (rust) so rather than spend £75 on a new one if I could do without..... Scope will be used for...

Re: First light for a "new" CaK PST (and 1st attempt to mod
I found that this stuff dissolves the threadlocker that they use on these scopes, takes a while though i.e. days with a daily re-application to the joint.

Re: Replace PST 20mm etalon with a Solarmax II 60mm one?
Hi Alan, As the original TAL 100R focuser was 1.25" and only had 25mm of travel I was faced with 2 options 1. replace focuser with 2" version before etalon and then put a helical focuser after it. 2. replace focuser with sliding tube and then a 2" focuser after the etalon. Picked item...

Re: Solar Projection Eyepiece
Wow 183 Euros, mine cost..... nothing as I used spare parts.
Must admit the Elio is better looking though.
We will be using this on SUNday as the image is up to 7cm depending on ep used.

Hi Aleksey, here is a picture of the offcut next to a rule in mm. Also attached is a photo of the adaptor which replaced the original TAL focuser.

Re: PST swap mod?
You can always convert your BF5 into a BF6 with the careful use of a pillar drill. Need to make sure it is 100% blocked around the edges though as the BF is 6mm square so the tolerance is non existent.

Astrotelescope, as its closer to F10 and as you use the etalon only there should be no difference (famous last words)

Not the best day's viewing yesterday in the UK, but late afternoon I had a couple of cracking views between the clouds. Loved the fact that compared to my TAL stage 2 mod I can have a full disk detailed view without a sweet spot. As I will be mounting both side by side on a Skytee 2 I could not be h...

Re: Replace PST 20mm etalon with a Solarmax II 60mm one?
Decided to get an adaptor made and single stack it on the front of the Equinox 80 instead and slightly modded the inside of the etalon housing to stop reflections.

Will even consider one with a rusted erf but would prefer it with an un-rusted one.

Thanks for your replies everyone, think I'm going to use it on a 66mm f6 scope for low power full disk and as Valery says keep the stage 2 for medium and high power work. Will also try it on front of the stage 2 scope but reducing the aperture down to 60mm means it will then be an f16.7 scope and ma...

Replace PST 20mm etalon with a Solarmax II 60mm one?
Hi, Is it possible to swap over the PST etalon in my Stage 2 scope to the 60mm one from my Solarmax II double stack unit? Sure I have read somewhere that the PST has lenses which make the light cone parallel as it passes through the etalon and then converts it back as it exits. With this in mind I'm...
