I fancy a Quark, roughly the same price as a Lunt 50, was hoping to get a used Lunt 35 when the 50's came out but they seem far and few between. From what I've read the Quark seems to be a good option for the price. Can't find much resent discussions on them only when they first came out, some saying to get a similar scope that's equivalent to the Quark you would have to shell out a couple grand. It should work well with my ED80 by all accounts. So if anyone has one what are the pro's and con's using one compared to a scope?
thanks John

Sorry John, I have nothing to contribute to the discussion because I have never heard of a Quark, except for the particle discovered in the Collider Is it a brand name?

Interesting John I notice that nowhere on the page, or on their flyer, does it say it is for Solar viewing. The only give-away is the name of the two models: The 'Prominence' or the 'Chromosphere'. Other than guessing what those names mean, it doesn't say exactly what it's for. Bad advertising. If they mentioned it is a 'Solar' viewing device it would get hits from people searching 'Solar observing' in search engines.

I am a relative newbie to Solar Observing and thus, I'm super cautious about Solar. The Quark makes me nervous -- I guess I would feel better if there was a wider adoption and I could see a lot of them in use. I'm not a fan of having to buy two to get both prominence and chromosphere detail. There'd have to be a lot of caution switching them out.
I am still researching the basics before I decide what to buy for a Ha solution -- and one that doesn't cost as much as a Planewave, hah!

As far as I can make out the Chromosphere is the more popular one to buy for some reason, as some has stated that both of them will do both prominence and surface detail so you just need to buy one. I'll see if I can hang on for about a month

John, there must be a difference between the 2 models or they wouldn't have 2 names.
Might have to dig a bit deeper for info. Their own website isn't very helpful.

Ahhhhhh . . . I found the difference. This mob really don't know how to put an advertisement together It's probably the most asked question ("What's the difference between the two?") yet it isn't easy to spot, but it is on the Flyer way down at the bottom left of Page 2 www.daystarfilters.com/downloads/QuarkFlyer.pdf
My suggestion would be the 0.8 ~ 0.6 Angstroms (the Prominence) if you already have a white glass, or solar film Filter. The WhiteGlass/film will already show surface granulation and sunspots because they go from about 0.3 up to about 0.6. Whereas the 0.8 ~ 0.6 Prominence model will go far beyond their capabilities and show Prominences which is why people buy the expensive Solar scopes.

If you want mostly prominence's, 0.8A-1.0A (cheaper) is all you need, if after really fine surface details, then the more costly 0.5A, which also shows prominence's as well.
My Lunt 60 DS system is native 0,8A but when the double stack unit is added it becomes 0.5 and a big difference in surface details in the spots, flares, filaments etc. My Baader Planetarium Solar Prominence Chronograph Mark IV came with two Ha filters 1.5A & 0.6A-the 0.6A was never supplied in the UK as sky conditions were never good enough. Note, the lower the A figure, i.e 0.5-0.3 -the cost increases out of sight, but so does the details in Ha. You get what you pay for, if the skies allow it. Daystar Filter temp controlled units were always the units to buy, but never affordable for the average amateur The dielectric coatings on these etalon's have fifty or more coatings, each one done under high vacuum and very specific thickness, hence the high costs.
Clear skies, Shevill

Thanks Ken & Shevell for explaining what they do, I've no idea what them numbers meant. So I'm I right in saying the Chromosphere version [ 0.5 - 0.3 ]is similar to a double stacked scope as far as detail is concerned? maybe that's why nearly everyone is going for that one?

John, please notice that all the links you provided show Solar images from the Quark that are stacked and very heavily Processed. The poster explains the amount of processing he has done.
They are fantastic results, but if you want to show this kind of view 'Live' then it may not look as good. As far as for imaging, they are great.
I also found a video from the daystar company where they say that the Chromosphere model show great surface detail and mild Prominence detail, and the Prominence model shows mild surface detail but great prominence detail.
It's a matter of which one you want to see best.

Cheers Ken, I've got a chromo coming hopefully for the weekend. This is something I'm looking forward to seeing how good it is or isn't for video and broadcasting, I might have a go at processing but haven't really dabbled into it. I don't have any processing software on my pc's. I think I've grabbed the last one in the country, I could only find 3 outlets that sell them and 2 have sold out and this was showing 1 stock remaining.

Cool John. I hope it shows great results for live video. Certainly cheaper than a Solar scope You did well finding one because their website says they are on about 2 weeks backlog for delivery as they are sold out

One seller I spoke to says his order is 3 weeks over due. There suppose to be a newer version coming out later this year, At the moment the filter as a Integrated, fully baffled 2 element telecentric 4.2X barlow optimized for 656nm and the new version it's going to be 2x barlow from what someone as posted. I'll just use a reducer if I want a full disc. The seller I bought off says they've been flying out of the window but there seems quite a lot out there but very little discussion's about them.

So I'm I right in saying the Chromosphere version [ 0.5 - 0.3 ]is similar to a double stacked scope as far as detail is concerned? maybe that's why nearly everyone is going for that one? I believe the numbers are a measure of the width of the filter. Or to put it a different way, the amount of light outside of exactly 656.28 nanometers (or 6562.8 angstroms) is transmitted. The lower the number, the closer to only transmitting that one, pure wavelength through the filter. And therefore, they can be more expensive. The wider the grating, the more light from other wavelengths comes thru and can "drown out" the detail and reduces the contrast. As I understand it, this is why you can't see as much detail / contrast with a normal Ha filter (12nm) or even a narrowband Ha filter (7mm) in conjunction with using a White Light filter. --Rick

It arrived late this evening, I was hoping it would of come with a 5 volt usb lead as well so I could plug it in the mounts power pack Luckily my cell phone as the same charging lead connector but its a bit on the short side. Hopefully I'll get a few hours of clear skies over the weekend

Nice one Johnno. lets hope you get some sunshine tomorrow so you can test it.
