Hi,
I am at the moment of deciding the acquisition of a solar telescope, my current budget places me between a Lunt 60 TT with a BF600 (of the old models) and a Coronado PST 40 DS, on the one hand with the Coronado PST 40 DS I can reach a 0.5 A for surface details and prominences, I suppose, on the other hand the Lunt 60 model has 20mm more aperture, higher resolution ..
I would really like to hear your opinions about it.
Very kind,
Pluton.

Re: Resolution vs. Details
Hi Pluton, I had a Coronado PST SS for many years (sold for buy the Lunt), now I have a Lunt 60THaPT/B1200 and I can say that the diffrence is noticeable. You can always add the Double Stack filter later (this is what I will do).
Hope this helps.

Re: Resolution vs. Details
Can you try both before Pluton?

Re: Resolution vs. Details
Heya,
The difference in aperture is worth getting the 60mm. I've done the 40mm double stack. I've done the 60mm double stack. I heavily prefer the views (visually) from a double stack. But, if you want to see things, especially for the next few years, aperture is going to matter a lot more I think. I would go 60mm single stack now. You can double-stack it later if you really enjoy it. While the contrast will be higher on the DS 40mm, it will be very limiting and also very dim. And when it's already that dim, increasing magnification just gets dimmer. Keep that in mind. PST's are a gamble. The Lunt 60 is way less of a gamble in terms of getting a decent etalon. Also, with the Lunt... way better focuser, better future upgrades, bigger sweet spot, and a bigger blocking filter (6mm vs 5mm) etc. All of this is better and makes a big difference later on.
Very best,

Re: Resolution vs. Details
What's the point of more contrast if you can barely make out the details you are trying to see? Just my 2 cents. I started off with a Quark and a 102 mm refractor that I had in my stable. It shows lots of details when there are details to see. And if you get one used probably in your budget (if you have a refractor).

The Quark introduced me to this wonderful side of the hobby and the sun hasn’t disappointed yet.
