2019年2月19日 · Doug, Although I do not own one, I think the APM 140 looks like the ideal doublet refractor these days for NV - especially considering the price. I thought I would add that the TV-140 with my NVD micro delivers that same (outstanding) views of DSOs that I used to get using my RC-10 with the Collins I 3 on board (and I published a S&T article ...

The new 140 offers true Apochromatic performance with outstanding sharpness and contrast. With its low F7 focal ratio the 140 is a very compact scope that weighs under 9kg making it an easily transportable scope that is well matched to smaller mounts.

2024年9月16日 · If your budget only allows for an APM 140 F7, you might consider the TS-Optics CF-APO 130 mm f/7 FPL55 Triplet APO. A 140 mm F7 doublet is pushing things optically compared to a 130mm F7 triplet. And for lunar/planetary, you want to consider optical quality over a slight increase in aperture.

On a variety of deep-sky objects, the 140 delivered exactly what its aperture and optical configuration promises: pinpoint stars set against a dark background, wonderful contrast on nebulae, and an overall “punching above its weight” when compared to scopes of other types.

APM Doublet SD Apo 140 f/7 FPL53 (2.5" ZTA) is an equipment item of class Telescope or lens on AstroBin equipment database.

With 980 mm focal length, the 140 mm SD Apo is an impressive all-rounder. From intricate double star observing to high contrast detailed planetary views, this scope will introduce astronomy enthusiasts to APM quality. Traditional APM quality has been applied in all areas. The 2.5" focuser is a rack and pinion type, with 1:10 focusing.

The new APM 140-980 Super ED Doublet will introduce a whole new group or astronomers to APM quality. Featuring an APM designed 140mm F7 doublet objective using a combination of FPL-53 super low dispersion and Lanthanum glasses. The new 140 offers true Apochromatic performance with outstanding sharpness and contrast.
