Weight about 22 kg

Is the objective from Istar? Is it one of their lenses specifically used for h-alpha?

Telescope still available?

Alessandro,
What a magnificent instrument. I am certainly impressed. It makes my Coronado SolarMax II 60 look very much like a beginners instrument. The resolution and image scale of your pictures are incredible. Among the best I have seen outside of a professional solar observatory. I hope you have been able to find a way to keep it and not have to sell it. I certainly would love to see more future work of yours using this instrument.

Is the objective lens an achromat or a singlet lens? Ha solar uses such a narrow band that a well figured singlet should work fine. Chromatic aberration shouldn't be an issue. But for full spectrum nighttime viewing that would be a big issue. Without being at least achromatic, chromatic aberration would be horrible.

I think only Lunt sells solar scopes commercially in sizes comparable to this. I think by special order only. They have a 230mm and a truss 300mm.

Hi James.
The objective lens is an acromatic.
I'd like to keep it but I'm using it rarely and this is a pity.

Alessandro,
It is really an awesome and unique instrument. Is the reason you don't use it much because of it's size? Many people will use a small grab-and-go scope far more than a big instrument. My smaller scopes certainly see more use than my bigger ones. A fixed permanent observatory will often remedy this though. I just wish I had the cash to go that route.

The ota is about 1,90 mt long and is weight is about 22 kilos
I'd like have an other roll off observatory (I've one in which there is a C14HD edge & 10Micron GM2000 HPSII) but it isn't possible because of my future wife :lol:
