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.

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/

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.

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.

Things were not looking very good last night in south central Pennsylvania for a successful observation of the NEA 2002 NY40. However, my persistence paid off in spades as I was fortunate enough to have a hole in the overcast develop on Sunday morning around 6:00 UT. Using the ASH 17" f/15 classical Cassegrain, which is not the easiest instrument to do this sort of observing with by the way, I located 2002 NY40 in the constellation of Hercules at 6:18 UT and tracked it for over 20 minutes. Magnifications of 162 (40mm University Optics MK-70), 259 (25mm U.O. MK-70), 324 (20mm Meade Wide Angle), 381 (17mm Pro-Optics Ploessl), and 498x (13mm Tele Vue Ploessl) were employed. At 498x it was quite difficult to keep the asteroid in view for very long. :-) I'd observed the speedy NEA 1996 JA1 with the same telescope 6 years ago but 2002 NY40 was much swifter, the fastest natural object that I've ever seen through a telescope other than the occasional meteor. Afterwards a fellow ASH member put C/2002 O4 (Hoenig) into view using coordinates that I supplied to him. The transparency was not very good but the comet was nevertheless visible. At 118x (55mm U.O. Ploessl), 202 (32mm U.O. Koenig-II), and 259x Comet Hoenig did not appear to be appreciably different than my last view of it a week before at Stellafane. The coma was diffuse and poorly condensed. I also was able to observe a number of denizens of the deep-sky through the 17" (at 118x) and its 5" f/5 finder - M57, M92, Stock 2, the Double Cluster, the Alpha Persei Association, Almach, M34, M15, M31, and Gamma Arietis - before the clouds returned.

I motored to the ASH Naylor Observatory (http://www.astrohbg.org) on Wednesday night to help with the observing portion of the Spring 2002 Introductory Observational Astronomy class and to photograph the ongoing alignment of the planets. When I arrived I first had a look at Jupiter through the 17" f/15 classical Cassegrain at 202x (Venus and Mars followed a bit later) and then set up my Pentax K1000, 50mm lens, and tripod. At 01:02 UT I took a 20 second exposure followed by additional exposures about 20 and 40 minutes later. Prior to that I'd alerted the students and other ASH members about an upcoming Iridium flare. At 01:27 UT Iridium 74 unleashed its reflective brilliance, reaching a predicted seventh magnitude. (The flare center was only 4.9 kilometers to the west.) Hopefully, I was able to capture yet another flare on film. After the brief flash of light I followed the satellite briefly through another ASH member's Fujinon 16x70's. Using the 12.5" f/6.5 Cave Newtonian I showed some of those present the Lobster Claw (Crater Gutenburg). The crater was situated for the most part on the unlit side of the terminator but its crustacean outline was unmistable nevertheless. I returned to the French Dome and trained the 17" on Gutenburg. After everyone interested had seen it I moved on to what I call the Tomahawk or the Reflex Hammer, the peculiar lunar feature located near Mare Crisium, and then increased the magnification to 259x. Another ASH member asked me to confirm his tripod mounted 10x50 sighting of C/2002 C1 (Ikeya-Zhang). The comet was to the north of the Great Hercules Cluster (M13) and seemed to be at least twice M13's apparent size. Both were easily visible in the same field of view. Next I put Comet Ikeya-Zhang and M13 into view with the 16x70's. I turned the 17" to the comet. Both objects were visible simultaneously through the 5" f/5 finder scope. At 162x Comet Ikeya-Zhang displayed an oddly skewed coma but no hint of its now dim tail was seen. The big scope next collected photons from M13 (162 and 259x). Two more ASH members had arrived while everyone else had taken their leave. One was going to look at binary stars with the 12.5" so I suggested Gamma Virginis. The rapidly closing separation of this system and only fair seeing made a clean split impossible with the 17" at 259x. Using a 19mm Tele Vue Wide Field (340x) did the trick. I moved on to another Gamma double, the golden Gamma Leonis (340x). Soon just one ASH member besides yours truly remained. I had a peak at M13 through his 10" Meade SCT before returning to the dome where I finished the night with a few spring deep-sky objects - M104 (162 and 259x), M84 (162x), and M86 (162x). Although I didn't do nearly as much observing as I would have on my own, I did manage to impart some knowledge to the students and accomplished some paper work in the classroom building as well as a minor repair in the dome. All in all it was three hours very well spent.

I spent most of Friday night and some of Saturday morning observingfrom one of the best "nearby" (a mere hour and a half drive from myresidence) dark sky sites. On the final leg of the journey mysignificant other and I stopped for a few minutes to view the closepairing of Venus and Mars through her Celestron Ultima 10x50's andthen drove up Little Knob to Camp Site 52. Tony Donnangelo, a fellowASH member, was already observing with his 10" LX6 Meade SCT when wefinally arrived.The night began with fair seeing and good transparency - a visuallimiting magnitude of perhaps a shade above 6.0. This was all tochange with the passage of time, unfortunately.Before too long I had my 101mm f/5.4 Tele Vue Genesis sdf refractorset up and trained on Jupiter at 193x (7mm Tele Vue Nagler type 1 and2.5x Tele Vue Powermate). (I had originally thought about bringing my12.5" f/4.8 Starsplitter Dob but since my friend Roger Studer had saidhe was going to come with his 15" Obsession I decided against it. Asit turned out Roger decided not to make the trip because of concernsabout the weather. Two other ASH members had also planned to come butan automobile accident thwarted them.) My next targets were M81 andM82. Both galaxies were easily visible through my 19mm Tele VuePanoptic (28x).I followed with Comet Ikeya-Zhang, which was to the east of the fineglobular cluster M92 in Hercules. The 60x view with Tony's new 9mmNagler type 6 was superb. Since Tony wasn't using the 9mm with his SCTI had a fine old time auditioning it. I was to revisit the comet anumber of times throughout the night and as it climbed towards thezenith its coma was clearly asymetrical although I could never quiteconvince myself that I could see a tail. The fifth magnitude comet wasjust on the verge of naked-eye visibility.During the course of the night I observed quite a few deep-sky objectswith the aid of only 4 inches of ground and polished glass. Theseincluded M101, M5, M13, M104, M65, M66, Gamma Leonis, M87 and otherVirgo and Coma Cluster galaxies, M3, Cor Caroli, IC 4665, Antares B, M4, M8, M11, and V Aquilae. The highly elongated "needle" galaxy sometimes known as Berenices' Hairclip (NGC 4565) was only a small streak of gray at 60x. Near the end of the session I had a fairly good view of NGC 7000 (the North American Nebula) using Tony's 48mm Lumicon O-III filter and my 35mm Panoptic (15x) despite its less than optimum placement.Through Tony's telescope I saw M51, NGC 4195, M81, M82, NGC 2976, NGC3077, NGC 3079, M97, M108, M109, M101, M94, M106, NGC 4631, M53, M84,M86, NGC 4435, NGC 4438, M3, and other celestial eye candy using a40mm Tele Vue Wide Field, a 22mm Nagler type 4, and a 17mm Nagler type4.Sometime after 06:30 UT the occasional horizon hugging clouds becamemore troublesome, spelling the beginning of the end as they began tocover increasingly large portions of the heavenly dome.The highlights of the night were seeing C/2002 C1 (Ikeya-Zhang) nearthe zenith through the Genesis sdf and later through the 10" SCT andviewing the classic edge-on spiral galaxy NGC 4565 at 28 and 60xthrough the refractor, as well as the heart of the Virgo Cluster (M84and M86) and parts of Markarian's Chain at 60x.

A beauty. At 120x a great number of stars were resolved. Three strong branches stretched out from the center, and the cluster had a 3 - dimensional look somehow. No sign of the dark dustlanes, though.

This planetary was a bit hard to spot at first. But after about 30 seconds of viewing I became confident that it was there. I used an ORION "broadband" nebula filter.

Why am I bothering to log an observation of such a mundane deep-sky object you ask? Because it was the first DSO that my friend Roger Studer and I observed after driving some 750 miles so that Roger could buy a 15" f/4.5 Obsession Dob that had been listed on Astromart just two days previously. (I went along for the ride and to help Roger evaluate the telescope.) Our observing site was the "close" one that the owner used and was well over an hour to the west of Chicago. This was by far the longest I have ever traveled to observe for just one night. We also observed M17, M27, M51, M57, M82, the eastern (NGC 6992) and western (NGC 6960) sections of the Veil Nebula, Collinder 399, Albireo, V Aquilae and many others.

I was sittin around the house one day and had planned out a night to take the telescope out and do some observing. So I did.I pointed what was almost the Zenith and looked at Hercules.M13 was the first object that came to mind.It was a splendor!I also observed M57,Alberio,The Veil Nebula and M92.

Got a great low power ob of M13 in Hercules. I could not resolve individual stars with my small scope, but still got some resolution of M13 as a "fuzzy." I was able to stretch my magnification to the limit of my small refractor (144x), but my Barlow (2x), just isn't worth having!

I've often seen the Hercules Cluster from my light polluted location many times but never as good as tonight. Using the Telradhere is usually difficult because the lights of the city make it impossible tosee all but the brightest stars. Tonight,all the necessary guide stars were readilyvisible. M13 was readily found in my 40mmeyepiece at 30x. It appeared as a smallhazy patch. Going to the 20mm wide angle eyepiece at 60x, the cluster began to take some shape. Individual stars were only visible using averted vision. I then dropped in the 3x Barlow and was given a pleasant surprise. I had never used the Barlow on a dim deep sky object before so didn't know what to expect. At 180x, the cluster appeared as bright as at lower power. But, now there were many individual stars visible. My upstairs neighbor who had never looked through a telescope before came out for a look. Her first comment was, "WOW", which I understand is customary for this object.

After viewing M13 and the nearby galaxy NGC 6207 at 118 and 259x I decided to look at DoDz 5 and DoDz 6, two sparse open clusters, while I was in that part of the sky. DoDz 6 was very sparse with only a few stars visible. DoDz 5 had an interesting shape and nine or more stars were visible, most of them fairly bright. Other objects observed with the 17" included Jupiter, M30, NGC 1528, Saturn, M33, and M36. I also viewed M27, V Aquilae, M11, M57, M15, M2, Epsilon Lyrae, the Double Cluster, NGC 457, Gamma Arietis, and Saturn with a 12.5" Newtonian.

The climax of my Hercules session; I definitely saved the best for last! A big, beautiful, condensed swarm of stars at 49x, with a central glow behind it. As with M92, the central region seemed irregular at 244x, while 122x gave the prettiest view.

A beautiful globular at 49x. Larger than NGC6229 (which I had just looked at), the outer reaches were clearly resolved into mottled stars. At 122x even the center began to show a mottled appearance, with some darker patches here and there. At 244x the center section appeared irregular. I think 122x gave the most aesthetically pleasing view.

An easy, small, round fuzzy patch, with a denser core, at 49x. I was unable to resolve it into stars at either 122x or 244x. Per Burnham's, m8.7, diam 3.5'.

It required careful starhopping in a star-poor region (I really need a Uranometria atlas!). Once I was there, though, it was easy to see this planetary at 49x, though it was hard to be sure that it was nonstellar. At 244x, though, it was clearly a small, round, uniform patch. I believed I could detect a slight greenish tint.

I wanted to do a quick magnitude check of this lyrid eclipsing binary, but it was right at the zenith, and after about 10 minutes of fiddling with my dobsonian mount I gave up, then forgot to come back to it later on in the evening.
