Question using Quark with lunt

Recommended Posts

Hi all, just wondering if you can use a quark chromosphere filter with a single stack lunt solar scope for lower angstrum observations. Thanks for reading.

Apparently yes, some users are doing so according to the "Solarchat" forum. I would imagine the visual view would be rather dim.        🙂

I thought there'd be no issues apart from brightness. Do you know of any specific posts? Do I just Google "solar chat forum?" many thanks.

Yes it is possible.  I tried it with my Lunt 60 in imaging conditions.  The problem I had was focusing the extremely dim image.  I would imagine viewing under such conditions is impossible.  The inbuilt 4.2x of the Quark is difficult to work around under UK seeing conditions.

I found it hopelessly dim with my LS60 sadly - not even close to forming a visible image.

Thanks for your take on it, much appreciated.

I’m curious to understand how others might have managed it too Nigella. Remember reading on Solarchat about someone new to solar ha claiming that he got excellent visual results from a Quark and LS50. Then there was a long explanation by Jen Winters - the owner of Daystar - why double stacking Quarks was not recommended - worth seeking out but clearly hasn’t stopped lots of people trying it.

Another case of not all Quarks being equal, having tried a few this is very apparent when imaging as the required fps/gain etc is wildly different to achieve the same image.
