Re: Quark Combo at low focal lengths

If you want a bit more contrast just stop the aperture of your scope down a bit.

Re: Partial Lunar and Sunrise

Heya Derek! Good to see you here again. Lovely shots as always! Not many stars to be seen in the centre of Sydney then I guess?

Lovely images Pedro! I watched it from the port in Barcelona with a school trip. Took binoculars along for viewing, everyone had a great time! There was an ISS pass too.

Does the quark perform well at f16.5 (combo with 2.5) and f26 (classic with a focal reducer)? Daystar says they like around the f30-40 range.
Go with what Daystar says, don't over complicate it! I'd get the Quark with the built in 4.2x telecentric.

Re: Why my Quark always refused to work...

You would need to take the little 12.5mm one out of the base of the telecentric in the quark, it just has a retaining ring. 2 blocking filters would make it awfully dark!

Welcome to the forum btw!

Re: Quark Users

My first response would be to take the Quark apart and reassemble it, my gut feeling is something (lens or filters) are pinched - I had it with my SM40 a decade ago. However, it is a new Quark so probably this is not the most feasible of advice ;) The bandpass across the image looks good Stu, so tha...

No it won't work. Don't waste your time. Many have been here with the same thought.

... I thought the only difference between Baader RED + IR filter was simply like a Meade 4000 RED + IR/UV filter [which I have] ... No, totally different beasts. The way the 4000 filter works is by absorbing energy, regardless of what configuration is used it will absorb energy and at some point cr...

Re: Quark Users

How very strange! That 90 degree cross hatching is peculiar. Does it rotate with the Quark?
