Hi all and a Happy New Year! :D
First Jupiter observations & sketches from this year: NPC & SPC - no details visible, only a grey to dark-grey gradation toward the poles; NTB - brown redish in color, no texture; NEB - brown-reddish with some texture in steady seeing; EZ - white, some dark barges are visible attached to NEB; SEB - brown-reddish, SEB present texture, the southern(preceding GRS) part seems more red then the northern part, SEB following GRS part it's more grey-reddish and the wake is visible as light grey; GRS - is pale orange; STB - very dark and proeminent, almost touch the GRS; Oval BA - very hard to spot, only in moments of good seeing was visibile

Comet LINEAR C/2012 K5 from my location was difficult to saw, mainly due to light pollution and hazy skies at the observation date. I estimated at ~10 mag., DC=2 and 4'-5' in diameter, no tail visible.
All observations are made with a 90mm f/10 refractor.

Hi

Very nice sketches. You represented the comet exactly he same I can see from my backyard. Its far from some other observers where they can see a tail like Christian and Michel.

Thanks! Yes indeed, beeing a small instrument I'd say this are opposite sketches to those made with larger instruments.

hi Catalin,

You made very detailed Jupiter images with 3.5".

Bye Christian

Fine sketches!

ps I know you are a "fan" of a Neodymium-filter for planetary use. I bought also one, but can't see any improvement on Jupiter with my 12" dobson :shrug:

Welcome back, Catlin. You did very well with Jupiter in your 3.5". And to capture LINEAR is cool. I missed it, but then again MCTs aren't exactly "comet catchers."

Someone was saying this one would brighten significantly. I mean daytime bright. True?

Hi Norme,

That potential daytime visible comet is for the end of this year. The comet is C/2012S1(ISON). I'll believe it when I see it. Check out the magnitude guesses on this well known Comet site.

Thanks all!
Jef, what I found with M&S filter is that the improvment is subtle, but is there, especially in the reds and blues. I say to give another try. :grin:
Norme, as Frank said comet ISON is the potential a daytime comet, we'll see in autumn. C/2012 K5 is not the one, but even with your MCT you'll see it. ;)
