Lunt 60mm D/S SM60 ZWO 178mm cam

don't miss the proms below

 

Do the clicky dance for full res.

 

 

The close proms were taken with the Lunt 60 and the Quark daystar and a rather large extention tube.

Great shots, very high contrast on the surface features. You mention the Quark and the Lunt together in the same configuration? Are you using the Quark to achieve a "Triple stack" system with the Lunt and Quark?

Thanks a lot.

 

Not at the triple stage as yet just double, I also use x2 binning when I use the Quark one up or in the Lunt.

With my set up I have a JMI focuser and need about 150mm of extension once the blocker of the Lunt is out of the way.

it was a bit Heath Robinson as it was a hack of extensions .I have some ali tube on order that will find its way to the lathe chuck once it arrives on Weds ( I hope) then i will try triple.

 

I will put a picture up once I have it more presentable.

Replace the erf of your front mounted etalon with  a piece of clear camera glass, you should be able to find a plain old UV filter that fits and it will boost transmission by a ton.      

If you have a pressure tuner, theres an erf inside the scope already and you are losing 20% transmission by having two erf's installed via double stack.

Very nicely captured.
