I have a 60mm Lunt Ha tilt tuned scope and am considering getting a DS module for it. I noticed Lunt has both 50mm and 60mm DS modules for the scope. Will the difference in image between the 2 be drastic given that it is a loss of 10mm aperture in the smaller one?

The biggest difference will be the move to DS regardless whether it is 50mm or 60mm.

Get the 60 mm. At this aperture, 10 mm is a significant difference. With double stacking image brightness is decreased, and you need every available increase in light gathering area to mitigate this.

I was told that the DS 50FHa has reflection issues when used with the tilt tuner by Lunt when I called in to order mine. Later, I did some research and also exchanged messages with solar experts with scope experience, a few tilt tuner owners that has the double stack and they too recommended the 60FHa for the better contrast and avoid any reflection issues if that might happen. I initially ordered it but then cancelled and ended up getting the 60FHa. It’s def a huge diff in cost (double), but I haven’t regretted it. (Anything in this hobby is pricey, especially solar equipment). The double stack on the tilt makes a huge difference in view. Getting the full contrast really maximizes your experience in view and photograph of the sun. When I did observation of the sun this morning and yesterday, the prom lift just stood out so clear and with my binoviewers, it was like looking at it in 3D! As one who just went through the same thought process as you, talked to others and did a lot of research, I’d recommend the 60FHa to get the fullest potential and enjoyment out of your 60THa scope. The thought of the cost is painful that will only hurt one time, but the experience it brings will last a lifetime.

Another vote for the 60mm.  That is my exact set up as Michaels although I think his is a bit newer as all of the black portions are still black and mine are all bronze colored now!!

Thanks for all the input. Does the 60 DS module ever go on sale?

Haven’t seen that but you might check with Faye at Lunt to see if any refurbished units are available.

Sometimes they sell their gift cards with 10% off.  I've seen this at NEAF, although I haven't seen this lately.

Oh. One more question. Is there a reason why Lunt DS systems are more expensive than Coronado's?

As a Coronado owner, and someone who is currently evaluating a 90mm DS system, I would venture and say the Lunt quality is better.

That makes sense. Thanks for the input people! :)

The Lunt module is built like a tank. It doesn't have a central obstruction and is generally believed to have better optical qualities. The exception being the older coronados without richview tuning.

 

You can fit a coronado external etalon to a lunt telescope with a custom adapter. The combination is known as luntanado. It's very cost effective. I paid slightly less for a used SMII 60 + adapter than I would have for a brand new lunt 50mm.

I don't doubt that a lunt 60 would be somewhat better. But lunt 50 vs coronado 60 is a tougher call.
