Baader’s Quark

[Highburymark]

Interesting new H-alpha product from Baader/Solar Spectrum: Sundancer II - a Quark-like filter that can be slotted into a standard refractor. Pros: the etalons should be better quality than most Quarks. More adaptable too. Cons: price - almost £3k. See FLO or Widescreen Centre websites.

Oh my, it seems amazing but, after a peek on their site and a conversion to canadian dollars it would cost an exorbitant five thousand dollars!. 
 

Insanity!

Next week, you post look at my new solar toy 😉 🤣

Hmm looks like a high quality self build project, reminds me of a Leyland car, built from the parts bin.

With the Jaguar accountants putting the price on it. 🤨

Could buy a Lunt 60 B1200 for around £150 more 🤔

I am tempted to shop in my Lunt 60mm B1200 in favour of one of these or the cheaper Quark, to use with my 105mm refractor.

Some results posted on "Solarchat" were not impressive but to be fair, they were first light attempts.     🙂

F/30 on my 150mm? Not likely! It would put impossible demands on my typical seeing conditions.
I can't even add a 2x 'Shorty' Barlow to my PST mod. Have to make do with 'wimpy' GPCs on the nose of my '174.

Not sure why it requires an ERF upwards of 80mm when a quark requires it after 100mm if I’m correct.

I like the concept of oil becoming sulky 😉

The Daystar website says 80mm or above should use ERFs w Quarks, but if I remember correctly it can just be a (probably 2") UV-IR filter on the front of the diagonal rather than a full D-ERF?  Figure the same ought to apply to this new gizmo as well?

This seems correct, I believe I called them once regarding this and was told that a diagonal mounted ERF was fine from 80mm to 100mm, above that a front mounted ERF would be required.

I think the Baader 35nm Ha 2” filter is likely the best, effectively a mini D-ERF I believe.
