First ligth with etalons Quark combo and Lunt LS40.

I finished this build this morning and was lucky enough to get about an hour of sun. However, the conditions were very poor.

Glad to see you squeezing the last out of the winter Sun

That's a really great setup Pupak, with beautiful results.

Very good, but try it without the additional blocker.

I don't use two blocking filters. It's just Quark blocking filter. He is not in front, but behind Quark.

I can tell how low the sun is by the low angle of your scope. The sun must be just a few degrees above the horizon.

Beautiful surroundings Pupak!!

You should use it infront of your Quark, you risk damaging the Quark.

Great set up Pupak. Nice machining work on the etalon housing and the adapters.
Considering poor conditions the set up is already showing great potential.
What are the adapters between the draw tube on the Quark and the nose piece of the Player One camera and what are their purpose?
It seems to create a lot of back focus between the Quark and the camera. Is this needed?

At the input is a DERF 180mm, then a 2" H-a 35nm, behind it is a TZ3x telecentric element, a Lunt LS40 etalon, a Quark and at the end a blocking fitr. I don't see the slightest reason why the Quark should be at risk of damage.

The TZ3x has a large back focus (250mm), which is why the extension tube is in front of the camera.
