Obs Report and Sketch 25/26-10-10

Hi everyone,

Its been a long time since I have done any deep sky observing because of the Moon.This time though the moon was rising a little bit later on both evenings.

Monday night it was clear and I decided to do some observing.The telescope used was as usual my 130mm reflector with various eps.Conditions were clear so good transparency and quite good seeing.This also gave me a chance to observe the Grus quartet from the October obs challenge.

Jupiter- Jupiter like a beacon in the sky was like a magnet and as usual ended being the first thing I observed.I could see considerable detail on jupiter with band variations with darkening at the pole and a hint of wiggliness in the NEB.One thing i really enjoyed about jupiter was not actually jupiter itself but its moons it was the first time I noticed the satellites as discs and at 300x they looked awesome with me being able to discern different apparent sizes and colors which was lots of fun.

Grus quartet-After a bit of searching around i noticed a grouping of faint like wisps of light. after a while i was able to discern all 4.In the close grouping of the 3 ,2 where elongated and the third circular.the one furthest out and next to a bright star was one of my favorites being reasonably bright and elongated .This reminded me of my great time observing the leo triplet and I enjoyed this cluster very much.

M15-I couldn't believe my eyes when I had successfully observed m15 with my naked eye clearly.It being mag 6.Using my new 9mm Tmb (100x) on M15 it looked absolutely amazing being almost completely resolved.(ON the 26th i did a sketch of this glob(attached) aswell as seeing some old faves.)

47tuc-Since m15 was so good I decided to have a go at 47 tucanae.It was simply awesome showing much the same detail of m15 just bigger and dare i say better than omega centauri.It was very well framed at 100x mag in the 9mm.

I had 2 awesome nights of viewing,
hope you like my sketch
cheers orestis

Fine work, Orestis.

Your seeing the Grus cluster is confirmation that a small scope in good hands is a very capable instrument.

Tackleing a GC in a sketch is mighty brave. Sharp pencil and light touch a must. That's what I see here.

Any chance you and your old man would be able to come to Katoomba Airfield on November 6? If the sky is good, you might like to have a squiz through some other scopes.

You are certainly doing some fine observing, Orestis. To be able to seem so much detail including the galilean moons as discs with such a modest scope is very impressive.

Now to your sketch - absolutely brilliant. You've set the standard and thrown down the gauntlet to those of us who've baulked at sketching GCs.

And I agree - 47 Tuc is better than Omega Cent.

Thanks guys,

Its great to be having a few good nights under a clear night sky again.

Paddy-Seeing you guys talking about sketching globs,inspired me to try it out for myself.With this Glob I just smudged in a background haze and then semi-randomly placed the granulation noting how it got thinner the further you went out. ofcourse this isn't very accurate but it shows a close image of what i saw.

Clear skies to all
cheers orestis

Great report Orestis!
I see those TMB's are working mighty fine for you. Good glass really does make a difference doesn't it. You are have got such great observatonal skills, keep up the good work.

Regarding your sketch, wow, it is a beauty, and I'm with the others when I say, whoa you are brave! And succeeded beautifully!
I agree, I much prefer 47 Tuc to Omega Centauri. It's, well... prettier!

Nice job on that sketch Orestis On 47 Tuc, did you notice that the core appears yellowish and the outer regions blue? I seem to get that effect at low power.
