The Meteoblue weather forecast predicted good seeing, well below 2 arc seconds, for yesterday night, so I took the opportunity to take my A80M with the new lens to the fields next to our house. What a surprise!
I started with having a look at the planets, all quite low above the horizon. At 22:00, Venus was almost setting, Jupiter 13 degrees and Saturn 14 degrees above the horizon, Mars just rising. Starting with Jupiter, NEB and SEB were prominent, traces of festoons visible, the limb very sharp. More so with Saturn, sharp limb and sharp rings, Cassini's division visible, also some brighter zone around the equator. Compared to observing with a quite good ETX-90 which I had years ago, the views were definitely more pleasant in the A80M. Venus showed of course phase and color. But the color was only atmospheric dispersion, not chromatic aberration. Same with the other planets, no color except atmospheric dispersion. Mars again had a very sharp limb. It was difficult to see the South polar cap, I am not sure about that. But subtle surface markings, although with low contrast due to the current dust storm, were visible in the Southern hemisphere.
I moved to deep-sky objects. Stars were pinpoint up to high magnifications. I used the following eyepieces: 25 mm Meade 3000 (Japan) Plössl, 20 mm Vixen NPL, 11 mm TeleVue Plössl and 6 mm Vixen NPL. Epsilon Lyrae was clearly split at 83x, more so with black sky in between both pairs at 151x, nice Airy disks and dim first diffraction rings. I looked at Albireo just because I am used to do so every other time. Next came M 13. Although often claimed to be unresolved in apertures below 15 cm, I am confident to have seen some sparkle with averted vision. Same with M 11, the Wild Duck Cluster. M 71 in Sagitta showed a nice, glowing fuzzball, however unresolved. I switched to M 27 and M 57, both were prominent, their shapes were clearly visible. No UHC or OIII filters used. Any detection of glow inside the ring of M 57 is of course beyond the capabilities of an 80 mm scope. The next DSO were M 31, M 32 and NGC 205 which almost fitted into the field of the 25 mm eyepice. I rather should use a wide angle eyepiece next time. The last deep-sky target was a non-Messier object, NGC 7331. Once found, the oblong shape was clearly visible, the central region surprisingly bright for such a small scope. All that in steady, but somewhat hazy skies, I would estimate Bortle 6. I finished the evening at midnight with returning to Mars, now about 10 degrees above the horizon. Despite the bigger horizon distance, seeing slowly started to worsen, therefore I could not make out more surface details.
Now being asked whether I am satisfied with the A80M, I would say absolutely yes. For visual observing, I don't see any need for an ED or APO in this aperture class, except if you need a scope with a very short tube for travelling.
