Light pollution: light   Seeing: excellent
Time: Sun Aug 12 05:07:00 2007 UT   Obs. no.: 1690

I decided to try for an easier object for my first ever try at finding something on my own. Even through the small amount of light pollution from the street lights below, it was clear; the center was too crowded with stars to make out the individual ones, but the outer stars were distinguishable. I'm definately thankful I managed to finally stumble upon it!

M13 (Hercules Cluster) (Globular Cluster, in Hercules)

This evening my friends Mike Dzubaty, his son Mike, Steve Borer and I visited the Leitner Observatory at Yale University for a night of viewing through their big scopes. The first object we viewed was Venus in an 8" Schmidt Cassegarain. Venus is still slightly more than half lit. I noticed some albedo features at the terminator. Next we went to the 8" refractor to observe Saturn. The Cassini Division showed well on the planet. On the face of Saturn itself, I noticed two belts and the polar south polar hood showed well. We then went over to the 16" reflecter were we had the pleasure of observing the double star Iota Cancri. The brighter componant was gold and the dimmer star was blue. It's not known if Iota Cancri is a real double or just an opticle double. The grand finale was the globular cluster M13. In the 16" scope we were able to see an lot of individual stars in the cluster. Before we went home we watched an orange moon that was just passed full rise in the east. Another great night of astronomy!

Comet (Comet, est. mag 6, est. to be in Hercules)
Observer: Michael Amato (e-mail: abigmick@aol.com)
Instrument: 6-inch Dobsonian reflector   Location: West Haven, Connecticut, United States
Light pollution: moderate   Transparency: fair   Seeing: good
Time: Tue Oct 31 00:30:00 2006 UT   Obs. no.: 1575

This evening, my friends, Mike Dzubaty, Steve Borer and I observed Comet Swan with Mike's 6" dob and my 12mm televue eyepiece. With this fairly high power, we were able to see three seperate steller points within the head of the comet. The comet's center actually looks fragmented to me. Since a first quarter moon was out, we were not able to see a tail this time around. Finally, the comet still retained the slightest tinge of green color.

M92 (Globular Cluster, in Hercules, Est. RaDec 17h17m6s 437'58")

I think I've seen this one earlier but this time, it appeared beautiful, showing hints of resolution with a bright centre. One peculiar fact is that it appears brighter than M13 to my eyes!

NGC6210 (Planetary Nebula, in Hercules)

A very easy planetary nebula. It formed a sort of right angled triangle with two other sides with itself being the 'star' opposite to the hypotenuse. A greenish-blue disc, smaller than other planetaries. Dew and twilight did'nt allow further observations of the planetary.

Observer: Akarsh Simha (e-mail: akarsh_simha@fastmail.fm)
Instrument: 8-inch equatorial reflector   Location: Bangalore, Karnataka, India
Light pollution: moderate   Transparency: fair   Seeing: good
Time: Fri Sep 23 16:15:00 2005 UT   Obs. no.: 1336

An easy, bright, tiny planetary. Easy to locate (I nearly found it in the first shot). The field shows three widely spaced bright stars, a faint star and a comparatively brighter "star" (NGC 6210) visible only thru averted vision at 80x magnification. However at abt. 100x, it becomes more clear that tbe "star" is not a star and its bluish colour is cognizable. The blue colour is not so intense - definitely not like NGC 3242 or NGC 7009. Very faint blue colour was apparent. Best view on my scope was at 170x (an eyepiece of 9 mm focal length gives me this), where it shows an elliptical disc of small eccentricity (and probably a few filaments???). No more detail could be extracted.

Time: Mon Jul 25 22:30:00 2005 UT   Obs. no.: 1268

I just bought my 8" Dob. I decided to test dob on my favorite target, M13. At 38x cluster was a bright round fuzzy, but at 80x i show countless star. At 200x only core wasn't resovled. M13 gave me superb views.

M13 (Hercules Cluster) (Globular Cluster, in Hercules, Est. RaDec 16.7 36.5)

Light pollution: moderate   Transparency: fair   Seeing: good
Time: Fri May 27 22:00:00 2005 UT   Obs. no.: 1245

When I first observed M13 it seemed incredibly dim to me. Now its a standard DS object on my observing list.Through my 76mm scope it looks like round bright nebula with granulated edge at 38x. I estimated size to 5 arc minutes.Higher magnification (56x and 117x) only dim this wonderful object.

M13 (Hercules Cluster) (Globular Cluster, in Hercules)
Observer: Emil Neata (e-mail: forvert2000@yahoo.com, web: http://www.astroclubul.org/emilneata)

Light pollution: light   Transparency: fair   Seeing: fair
Time: Tue Jan 25 00:00:00 2005 UT   Obs. no.: 1173

Seen through a 60mm telescope, all globular clusters are small, nebulous objects. The only cluster I've managed to resolve into stars, only towards the edges, is M 13.

NGC6207 (Galaxy, in Hercules)
Observer: Emil Neata (e-mail: forvert2000@yahoo.com, web: http://www.geocities.com/deep_sky_astronomy)

Time: Wed Nov 10 03:00:00 2004 UT   Obs. no.: 1096

Separated only 25' from the famous globular cluster M 13, you will find NGC 6207, a magnitude 12.2 galaxy. It has an elliptic shape, with condensation towards the bright nucleus.

Time: Wed Oct 6 03:00:00 2004 UT   Obs. no.: 1071

Only had a few minutes tonight so I used the binos. It was crisp and clear with no wind. I laid down on the back deck and stared straight up at the Cygnus / Lyra / Hercules and Cassiopea region of starfields and slowly swept in everything I could see. North and East of Vega I picked up a smudge, towards the Hercules region. I knew it was not M13 but looked very similar. For a brief second I thought I had spotted a comet. After checking the star chart I realized what I had "discovered" was actually M92. Hazy yet conspicous in binos it seems to be similar to M13 in magnitude and apparent size. I will have to pull out the scope in order to see more similarities at a later date.

M13 (Hercules Cluster) (Globular Cluster, in Hercules)

Light pollution: moderate   Transparency: excellent   Seeing: excellent
Time: Mon Oct 4 02:00:00 2004 UT   Obs. no.: 1065

Decided to use my Celestron 15x70 Skymaster Binos due to having company over and did not have the 6" reflector cooled down. M13 was rather faint in the binos. The cluster was about the size of the full moon is to the naked eye. Very faint and could see only the core when looking around the edges of the FOV and not straight on. Last month I had viewed it with the 6" reflector. At 30x it was still faint, but then again there was almost a full moon and some evening haze in the air. I will try again this week.

NGC6058 (Planetary Nebula, in Hercules)
Observer: Giorgos Koronis (e-mail: giorgos.koronis@lies.com)

Light pollution: light   Transparency: good   Seeing: excellent
Time: Sun May 23 22:10:00 2004 UT   Obs. no.: 1003

I observed this faint planetary in Hercules using a Meade 8.8 UWA eyepiece (103x).Field identified with the help of Cartes du Ciel software.It was a small faint and feauterless round disk, better seen thru an O-III filter.

M13 (Hercules Cluster) (Globular Cluster, in Hercules)

Light pollution: light   Transparency: fair   Seeing: excellent
Time: Sat May 1 20:30:00 2004 UT   Obs. no.: 1204

this globular cluster appears a little spread out than other globulars through my scope.but by averted vision it really looks beautiful though not resolved into stars.

Other (Other, est. mag ~15.0, est. to be in Hercules, Est. RaDec 16h42m, +36d42' )
Observer: Dave Mitsky (e-mail: djm28@psu.edu)
Instrument: 30-inch Dobsonian reflector   Location: Cherry Springs State Park, Potter County, Pennsylvania, USA
Light pollution: none   Transparency: excellent   Seeing: good
Time: Thu Aug 28 02:00:00 2003 UT   Obs. no.: 876

I observed IC 4617, the dim Index Catalogue spiral galaxy near M13, for the first time through Tom Whiting's new 30" Dob at Cherry Srings State Park two days before the start of the Black Forest Star Party. M13 was fantastic at 388x and at 11.6 magnitude the spiral NGC 6207 seemed extremely bright through the large aperture. IC 4617 is situated 14.4' NNE of M13, approximately halfway between NGC 6207 and M13, and seemed rather small at 1.2' x 0.4' but not particularly difficult to see. It appeared as a tiny, circular, non-stellar object. An image of IC 4617 is available at http://www.justjim.com/ctsp/

M13 (Hercules Cluster) (Globular Cluster, in Hercules)

Light pollution: light   Transparency: excellent   Seeing: excellent
Time: Sun Mar 30 08:00:00 2003 UT   Obs. no.: 796

Last night was my first observation of M13 since last fall when it was lost to the sunset. It amazed me once again in its size and brightness. At 205x, the entire cluster was clearly resolved and bright with masses of stars forming shapes and knots sprawled throughout the cluster. Taking advantage of the great seeing, I went to 310x and almost fell off my stepstool. I was peering directly into the center of the core. At 310x, the outer portions of the Halo spilled outside the FOV. I then went to 410x and was able to look through the thousands of tightly packed the central core stars and out through to the space behind. My best view of M13 to date. One of these days, I'll have to get behind some really big glass to check this cluster out.

Light pollution: light   Transparency: excellent   Seeing: fair
Time: Sun Sep 1 03:00:00 2002 UT   Obs. no.: 707

M13 showed all its beauty tonight. The stars seemed to form patterns as they stretched out in what seemed like arms....with knots and bulges of stars sprawling out from the central core. It completely filled the field of view in the nagler.
