Dai hai fatto 30...fai 31 e via...

Io sarei per il Lunt152 Ready to dream!
Il daystar 0.4 a mio avviso non ti darebbe prestazioni top se non altro perchè lavoreresti con un tubone boiler quale è il C9 1/4 che con il calore diurno non ti permetterebbe di raggiungere un ottimo potere risolutivo.

Dai hai fatto 30...fai 31 e via...

Inaitial tesing of the first 152T scope has been done:

In Hydrogen-alpha: The scope could be brought to a sharp focus, the detail could be brought thru via the pressure tune system and the detail was very good. Seeing was little off due to the rain we had this morning and the residual humidity both in the air and coming off the warming asphalt. However, I am very please with the results.

In CaK mode: The image could be brought to sharp focus but was very dim. The culprit appears to be the IR window intoernal to the system. Initial specs from the supplier indicated that the IR window had T from 350 to 750nm, However, further testing would indicate that there is T from about 390nm up. The spec was missed. We should be able to get replacement IR coated windows in a few days.

In White Light mode: (yep does that too). We placed a Lunt White Light Wedge in the back of the system and I was very pleased at the amount of detail I could see. The granulation was easily visible and the current active region was pleasant to study. The image gave the skightest hint of yellow probably due to the slight reduction in T at the red end of the spectrum. However, I found the color easy to view.

I am currently guessing that the scope will also work well for night time observations, and the addition of a pollution filter might actually improve that slight color difference.. (I guess you can't have everything). The scope is a Solar Scope first.

The next step is the rework of the IR window coating by the supplier.
We will be ordering cases and getting foam done.

I will try to update as things move forward, but I am hoping to start shipping in about 2-3 weeks.

Si Fulvio l'ho pensato anche io e mi conviene cosi.
Dopo aver smosso un po le acque con qualche lamentela nei loro confronti, e penso di averne il diritto poiche ho dato un sostanzioso anticipo, il Sign Andy Lunt sul loro forum ha publicato qualche giorno fa i test in progresso dello strumento.
