New Lunt LS40

[richard ashbee]

So what are peoples expectations from this new scope, i gather it can go DS as well

Yeah, looking forward to peoples reviews and images.

The big question for me ... in terms of performance and satisfaction, just where does it sit between the PST and the Lunt 50mm ??  

Is it worth the step up from the PST or should I future-proof myself and go for the 50mm ??.....hmmmmn.....  ( wake up Craney... dreaming again...!!!)

I would expect it to be on a par with a good PST, nothing about it suggests that it would be a significant step up from one.  The appearance and mode of operation will likely appeal to many.  I look forward to hearing reports.     🙂

The Lunt should be quite superior to the PST, as it has an "External Full Aperture Lunt Etalon with tilt-tuning adjustment allows for a 0.65 Angstrom bandpass" Vs the PST which has "1.0 angstrom hydrogen-alpha (Ha) bandpass".

- External vs Internal etalon - score Lunt as external etalons perform usually better

- Bandpass - score Lunt by wide margin

- BF - score Lunt. Both come with 5mm, but Lunt can be upgraded to 6mm or 12mm

- Focuser - Even, as the helical focuser on the Lunt is bad, but the PST is hard to use for imaging due to weird internal focusing mechanism. However, one can upgrade to a 1.25" FTF (and probably equivalent Moonlite) on the Lunt

I had the PST and now have the Lunt 60mm; and I have played extensively with the Lunt 50mm.

They are all lovely scopes, but just the bandpass difference is enough for me to know which I'd buy
