Re: another PST stage 2 mod

AR150/F6 works well with TV5x PWMT and Quark which is similar to PST. You get F30 and the details are OK. I dont want quark because a few years sold him dont like this device. If you know pst wants f10 without vingetting and Lunt 50 wants F7. But now want better choice for my AR150/F6. If you know ...

Re: sweet spot and f/d effect

Bob thank you for answer! So the collimator in the previous Lunt 60 LS60THA vs the latest modular Lunt 60 LS60MT are different. The problem with the LS60 is that the collimation lens also works as a Barlow 1.89 x and the objective is F4.2. It is difficult to find a larger diameter with a similar par...
