Re: Cold weather etalon performance

Thanks Brian, I'm near Fort Frances, in between Thunder Bay and Winnipeg. We moved to a lake home that has some great skies, but there are temp extremes. So if I ordered a Lunt 60mm say, there is a VG chance it will work right out of the box? My Quark had to be tuned for my set up and temps...we'll ...

Cold weather etalon performance

I'm still tossing around another Ha set up besides my Quark and have a few questions. My weather here is extreme- right now its -26c with a bright sunny sky and with some VG seeing around here. Will a Lunt 60mm-internal air spaced etalon come on band from the factory? I'm at 1100ft with temps from +...

Re: Quark visual image too dim, please help

Its the exit pupil... the "barlow" of the Quark (about 4.3x)... starting to get pretty small with your eyepiece. My best views with my 90mm f7 are had using an eyepiece reducer and a zoom, but it works great on my 32mm,25mm TV plossls. Finding a low mag, 1.25" eyepiece without a "floating" exit pupi...

I'm shocked to hear this sad news just now, I have had no internet for a while due to a move. RIP Walter and my condolences to family and friends.

Re: Quark EP issues ?

The 32mm TV plossl has a difficult eye position as the exit pupil is extended past the eyecup. An eyepiece focal reducer screwed onto the 32mm TV pulls the exit pupil in and gives a nice useable reduction. My favorite eyepiece with the Quark is a zoom with a 19mm field stop @ 25mm and used with the ...

Excellent images as usual Valery, I must say that I don't like inverted images much- just my own personal preference.

Re: Help! UV/IR cut filter as ERF for Quark

I use Beloptiks UV/IR filter on my 120ED/ prism diag for the mini ERF. I heard Daystars UV/IR is from Astronomik and the Baader is said to work very well, more reflective than mine I think ( not positive).

Re: June 13 2015 Active regions through a 150mm telescope.

Awesome images Valery! I was observing today and saw the "spikes" in your second image- what are they called? and also the bright area they came from? Very good seeing here today.

You have very good high res images Valery :bow

Re: Polarizer for visual/Quark

Thank you Alexandra, the info in your links is fantastic. I briefly read them a while back and am going back for another go at it. The graph of the DS vs the SS shows the difference of the "area under the curves" which makes sense to me. I never considered that the polariser may reduce out of band l...

Re: Polarizer for visual/Quark

Thanks Valery- why would this filter enhance the views? The proms like more light with it and the surface detail less. Does anyone image using such a filter? My views are very good to say the least, I had seeing allowing 200x+ in the SW120ED the other day. I appreciate the patience :? I hope to unde...

Polarizer for visual/Quark

I have received my Quark back from Daystar and it is working well- no banding, for visual at least. Obviously I've been playing around trying different things and I found that my Baader single polarizer works great for increasing disk contrast-why?! Also when I rotate the EP/polarizer the view can g...

Re: Filament Jump

I watched the event starting as a triangular solid lump on the sun, to the jump and disappearance. The view through my Quark 90mm SV APO was photographic like- very high detail and sharp as a razor. The SW120ED upped the view again. Great catch ishua! I hope some others caught it too.

Re: Imaging set up

Budget is a concern and so is early success! I'm viewing the sun with the Quark in good skies and am shocked at the detail, razor sharp with a nice line of fuzz and little spikes all around the disk. Sensitive to mag this thing- sensitive when imaging? The HEQ5 sounds like a mount that would be good...

I had the opposite problem...Daystar could not guarantee that the Quark would come on band in ambient temperatures of 40 degree and above - getting more and more typical here in Oz. I passed on buying one.... I'll post this summers experience with the Quark- we get some hot, humid days but the seei...
