One of the many objects that my friend Tony Donnangelo and I observed from a dark site in the Tuscarora State Forest on Sunday night was the planet/Kuiper Belt object Pluto. Pluto was not terribly difficult to see through Tony's Starmaster once it had been positively identified. To the east of Pluto's postion was a diamond-shaped pattern of four faint field stars. A field star to the west when added to the diamond formed an asterism that resembled the constellation Delphinus. Pluto was but a dim speck to the west of that star.

Rho Ophiuchi is a triple star very close to Anteres. At 48x the main componant star has a blue white tinge to it. One of its fainter componants seems to be a bluish colored star. The other fainter componant appears to be yellow. The triple star can even be split in 10x50 binaculars, with a little difficulty. To find this star in binaculars, simply put Anteres at the bottom of the field and Rho Ophiuchi will be just above the middle of the field.

(Hopefully the mistake is mine, but can't I add nothing more than NGC and M-objects here? Fix it or fix me, please!)IC 4665A pretty easy catch to the naked eye. Faint large glow, with at least 2 stars visible (magnitudes, 6.85 and 7.14). With keen adverted vsion a couple more stars could be spotted.

I have been observing Mars at every possible opportunity as it nears opposition on June 13th. Until Saturday, Sunday (briefly), and Monday nights I had not been able to view it through the 17" f/15 classical Cassegrain at the ASH Naylor Observatory (http://www.astrohbg.org) for some time. From my residence I had been using my 101mm f/5.4 Tele Vue Genesis sdf refractor, my 114mm f/7.9 Celestron C4.5 Newtonian, and my 150mm f/10 ATM Dobnewt with a variety of magnifications and Wratten #21 (orange) and #80A (light blue) color filters. What was most striking about those observations was the fact that I could clearly see Syrtis Major on the morning of 6/9 at only 45x through the refractor. On Saturday night I traveled to the ASH Naylor Observatory (http://www.astrohbg.org) and spent a long time viewing and sketching the Red Planet . The seeing was fairly steady and I was able to use magnifications of 202, 249, 259, 324, 381, and 404x with and without #21 and #80A color filters. For a period I tried stopping down the 17" Cassegrain with 6" and 10" aperture masks. Syrtis Major, Sinus Sabaeus, and Mare Serpentis were quite prominent . However, I could not make out the Hellas Basin to the south of Syrtis Major. The central meridian at the time of my sketch was approximately 309 degrees. On Monday night the seeing was not quite as good and was more variable but magnifications of 162, 202, 249, 259, 324, and 404 were supported at times. In addition to the light blue and orange filters I used red, yellow, and magenta color filters. Mars was about 20" in size and Syrtis Major was again very prominent.

This was the first acceptable view of Mars that I've had during the 2001 apparition. Using Wratten #21 and 80A color filters and magnifications of 202, 249, 259, 324, and 381x I managed to catch a glimpse of what was probably the South Polar Hood and a dark surface feature.

Time: Mon May 10 07:52:00 1999 UT Obs. no.: 454
Using the finder chart from the March 1999 edition of Sky & Telescope and magnifications of 118, 202, and 259x I located distant Pluto. It was just to the east of a star that is directly on Pluto's orbital path at the May 11 tick mark. I was able to verify this observation by noting the westward change in position of the planet on the following two nights. On 5/12 UT Chris Fenn, a fellow ASH member, tracked down Pluto with his 10" f/10 Meade LX50 and my assistance.

I went up to Mt. Pinos (elev. 8000 ft.) where many amateur astronomers regularly go during the new moon. From there, I was able to view what I think is little known globular NGC 6535 (it was the only cluster on the star charts near where I was looking). NGC 6535 looks like a loose cluster that is being partially obscured by thin tendrils of gas. Although it is quite dim, the seeing was excellent through my C8. I could easily see all the stars as points at about 75x.

I spent about an hour tonight before the dew took over my enviorment looking all throughout this great constellation. Lots of nice open and globular clusters can be found within it's boundries. Well worth a longer look another time!
Barnard's Star (Star, in Ophiuchus)

This was my first observation of this 9.5 magnitude, M4 red dwarf since last summer. Barnard's Star has an absolute magnitude of 13.2 and has a luminosity only 1/2300th that of our sun's. It is the closest star, other than the sun, visible from mid-northern latitudes and has an extremely high proper motion of 10.31"/year. Barnard's Star was easily visible to the northeast of the apex of the "V" of faint stars on the finder chart in _Burnham's Celestial Handbook_. I used magnifications of 121 and 159x.

Very similar in appearance to M10. I swung the telescope back and forth, examining them at 49x, and eventually decided that M12 was a hint sparser, with more bright members resolved in front of the background glow.

A medium-sized faint patch at 49x, detectable with direct vision, but needing averted vision to see at all well. Finding it with the Tirion Sky Atlas required a tough hop through a fairly star-poor region.

Larger and brighter than NGC 6293, fairly uniform (i.e., not condensed). A somewhat oblong glow, appearing longer north/south than east/west. Begins to show hints of resolution at 122x. Checking Burnham's afterwards, was gratified to read that "M19 is one of the most oblate globulars." PSS print also shows the obvious elongation north/south.

The Flamsteed designation project still undone, I have to give this object as "Other," but it's really 36 Ophiuchi. A close pair of white stars, of equal brightness, just barely split cleanly at 49x. Burnham's gives magnitudes of 5.5/5.5, separation 4.4".

Very similar in appearance to M80, but a bit less condensation towards the middle. An easy round glow at 49x. No resolution into stars at 122x or 244x. Cannot say I noticed Burnham's "unusual irregular outline."
M12 (Globular Cluster, in Ophiuchus)

I recall seeing M12 from my suburban (and more light polluted) backyard while doing the Messier list, but here at Alpha Ridge where the skies are noticeably darker I find that it is far more beautiful than I remember. It is a bit fainter than M10 but obvious when it slips into view at 28x. Even at this low magnification I can see that this is not your normal globular; it is loose in nature, uncertain whether it wants to fall into the Globular Cluster or dense Open Cluster camp. The field here is also a plus with many background stars. With the nice field and looseness of the globular it certainly brings M71 to mind, one of my all-time favorite globulars setamid rich Sagitta. The field stars boldly come right up to the object with maybe even one or two mingling as foreground points of light on the globular's periphery. The view at 75x is to beenjoyed as it accents the resolution better and still keeps a lively field. M12 seems to have a misty glow maybe about 5-7 arc-minutes wide, and there certainly does seem to be less of the mandatory symmetry characteristic of globulars. The 9.7mm gives a nice view but again tends to wash out this particular deep sky object.
