Gorgeous pictures and scopes Gus. The new Stowaway looks quite stubby in your images.
It's solid, Erik, very solid. Next to it the original looks svelte and minimalistic. But there is less than 0.3 kg weight difference between them. The original was made for the photography of that time, 35mm film and early CCD cameras, the new for today's large cameras and the difference in focusers reflects that (2.5" vs 2").
Marty at Company 7 described the new Stowaway as "refined" and I certainly agree, everything is elegantly done. Even down to the rings, on the original the rings are held together with four recessed hex head bolts, on the new beautifully made tapered knobs.
I wonder why the original Stowaway is longer? The focal length is 604mm compared to 612mm for the new Stowaway. If anything it should be the other way around. Something in the focuser or dewshied perhaps? The original didn't come with a 2" to 1 1/4 adapter? Coatings look less pronounced than on the new scope. Could this have anything to do with oil vs air spacing? Are the coatings on the original also green? Your photo seems to show a hint of this. New version seems to have more baffles. Is there a noticeable weight difference? Assuming the original also has a dovetail bar attached. No one can complain about the font on the lens ring of the original .Looking forward to a shootout between the two but I doubt any differences will be perceived at least visually, perhaps for imaging.
Good question, probably the larger focuser. The original did come with the 2" to 1 1/4" adapter but I store it with the AP engraved desiccant cap in place (sadly no longer made). Reflections do appear more pronounced on the new, it has more effective coatings (0.2% vs 0.5% reflectivity) but four more air-glass surfaces, overall transmission greater than 97% for both so it is a wash. But the impression is almost no visible reflections in the original, what is there has a very slight purple tone, just like the other EDF scopes of that era. I didn't use a flash for the shot of the objectives so the baffles aren't obvious but the original is baffled all the way through the focuser draw tube to the back, couldn't fit any more into the scope.
You're right, no complaints about the font on the objective ring! I expect them to perform identically visually. The original Stowaway has the best optics I've ever seen in a scope, with a very close second to the TSA-102 and the APM/TMB 100/800.
Edit: For a tracking mount for the Stowaway I use the AP 400 GTO mount on the AP wood tripod with the Lapides spreader. Perfect combination.
