I’ve had some better views this season, but had not bothered to start sketching yet—Dean seems to have given me a little inspiration.
Seeing was medium soft but with occasional sharp moment. I was out with my 12.5 f/6, finally settling on about 230X (8mm Delos). Time about midnight on the 13th/14th.
NEB showed a braided appearance with a notable bright spot in its middle; two fairly prominent garlands, the following one more pronounced, rose from bulges in the equatorial side of the NEB, with suggestions of another. I’ve shown them a bit too strongly here.
NTB well separated; NNTB suggested by a strong linear concentration with a bright region underneath it (that is, to its north). NPR otherwise featureless.
SEB relatively featureless on this side of the planet, save for some subtle concentrations. STB showed a very fine line suddenly broadening to a wide belt; this was clearly detached from the region to the south by a bright zone; later, this wide part of the belt ended—in all, it was about as long as shown here; SSTB very faintly distinguished from SPR by a lighter zone, quite subtle. A notable concentration, perhaps more oval than bargelike, was seen along its northern edge, preceding the “fat” part of the STB.
The moons were clear disks; Ganymede led, showing no detail (I’ve seen some brighter markings previously this apparition); Io, Europa, Callisto followed.
While I settled on the 8 Delos this evening, I have to say I really enjoyed the view in a barlowed 18mm Celestron Ortho from yesteryear—a symmetrical, not an Abbe—in a 2x Televue barlow it gave a comparable magnification and similar detail to the Delos, with a bit more glare perhaps.
12.5-inch f/6, 230X, UT 8:00 14.12.13. Seeing 3/5, in occasional moments 4/5.
