There are two versions.

Described on UK sites as a "new" style? If so, won't previously owned versions be older models?
It's this one I was looking at, though there's another Quark-C....
"This new, All-In-One design marries high quality components of a telecentric barlow, adapters, snouts and Daystar hydrogen alpha filter into one simple assembly."
Now you're starting to get beyond what I can help with. I know that a scope atBikerdib wrote: ↑Wed May 22, 2019 3:56 pm I actually do have one question. I have the ES 80mm and the Clestron XLT 102mm (and of course the 152mm but doubt I'll use it with the quark), the ES falls within the recommended f ratio but the 102mm is f9.8. Is the only drawback of the longer FL just going to limit the FOV or is there another consideration?

Sounds like most times I'll be using the 80mm because my local seeing is seldom above 3 out of 5. I do have the full line of Tele Vue plossels so I'm set as far as eyepieces.
My 152mm triplet is f/8 but I'm just a little concerned about the heat that will be generated inside the rig with that much aperture. Maybe sometimes in the future I can get a objective end ERF for it.
Very nice captures BTW.
I agree. At first, I would start off with only the UV/IR cut filter in front of your diagonal. Remember that your refractor aimed at the Sun will present very little of itself for any heating, and the Sun's energy will be cut by that filter prior to entering the diagonal. Very little left to heat up. The stories that I've seen posted seem to claim the same - don't worry about the ERF unless you're going larger than 150mm

Bouncing the energy at the diagonal will heat up the tube and can cause air currents that will mess with imaging .
Without an external ERF if you remove your Quark with the scope still pointed at the sun you will have no problem starting fires at the focal point .
Always be aware of the energy you are dealing with , especially when using scopes without a front ERF .
Sorry to barge in here , just wanted to add my 2c worth from a safety point of view
Thank you. Have you made up your mind on what solar set up you are going to get?
Can you 'find' a way to trial both? Given the price it'll be a "sensible" way to go. :twocents:Lady Fraktor wrote: ↑Fri May 31, 2019 12:53 am I have not decided if it is going to be the Coronado SM III or the Lunt yet.
