NGC3596 (Galaxy, in Leo)
Observer: John Callender (e-mail: jbc@west.net, web: http://www.west.net/~jbc/)

Shifting to the region of the lion's tail, NGC 3596 was a medium-sized, circular, difficult glow with averted vision at 38X.

Had the newly completed third generation of my8" Dob out. I initially started out in this part of the sky (Leo) to track down M65/66. Having not looked for the two w/o DSCs for some time, it was a little tough.However, while slewing around in the area I came across a faint 9th or 10th mag fuzzy. Later on that night I found it was NGC 3521.The object showed a brightening towards the center with fading fuzziness around the edges. No spirality; just an elongated patch of white light at 41x (2" 30mm Antares wide).Although, at 82x (2" 30mm w/ 2" 2x barlow), the galaxy looked to have two nuclei! Two distinct bright concentrations were seen in the center of the galaxy. They did not appear to be tight together, though.

We observed the periodic comet P/Wild 2 at 159x on Tuesday night. This dim fuzzball, which will be visited by the Stardust coma sampling mission in early 1999, was almost at the limits of visibility.

Last night I finally had a chance to see the Frosty Leo nebula (IRAS 09371+1212), a bipolar reflection nebula surrounding an 11th magnitude star about 2 degrees northwest of Omicron Leonis (see p.68 Astronomy April 1997 and p.188 Uranometria 2000.0). This nebula was the topic of conversation on the amateur astronomy newsgroup some time ago. At 317x it appeared definitely nonstellar, resembling a football perhaps. No color was noted. The object is not listed in the Uranometria.
NGC2903 (Galaxy, in Leo, Est. RaDec 09h 32m)

Despite high clouds we were able to do a little deep-sky observing on 4/29 (4/30 UT). Through some occasional sucker holes we observed the ninth magnitude spiral galaxy NGC 2093 south of Lambda Leonis. This Herschel 400 object is fairly large and elongated (11.0' x 4.6'). We used a 40mm Orion UltraScan (127x), a 32mm Tele Vue Wide Field and a 27mm Tele Vue Panoptic (188x) to view NGC 2903. We also viewed the "Leo Trio" of M65, M66 and NGC 3628 using the 27mm, which produced quite excellent images of these spiral galaxies.
M66 (Galaxy, in Leo, Est. RaDec 11h20.2m +13.01)

Time: Sat Apr 12 17:30:00 1997 UT Obs. no.: 119
Both M66 and M65 were in my field of view. This was my first look at two galaxies in the same field. M66 & M65 were in a small but noticable star field of 15-30 stars that seperated them. This star field was small and only noticable around the galaxies. Both were a fuzzy patch with little feature under the conditions fo the sky. However, I could tell the difference by the magnitude and angular tilt and seperation. Both were easy to find due to the lack of any other activity in the field of view. This was a fun object to observe and can't wait to visit again under better sky conditions.

Fairly difficult at 49x; a faint, small fuzzy patch that was definitely nonstellar with averted vision.

Brighter and smaller than NGC 3686, 3684, and 3681. Easy to see, but required averted vision at 49x to detect its fuzziness.

In field with NGC3684 and NGC3681. All three required careful looking with averted vision at 49x. All three seemed pretty close in size and brightness, but this one (NGC3686) was the largest and easiest, by just a tad.
Struve1547 (Multiple Star, in Leo)

Neat color contrast; the yellow-white primary and a much fainter, brownish secondary. Easily split at 49x, and that power gave the most pleasing view; at 122x the secondary faded to a dull gray. I estimated the PA at 345 degrees. According to dObjects, PA is actually 326, separation 15.4 seconds, mags. 6.1 and 8.2. Per Burnham's, spectral classes are dF7, dK6. This star is actually 88 Leonis; I need to fiddle with the AAOL object database to allow using that designation.
NGC3810 (Galaxy, in Leo)

Time: Wed Mar 12 05:20:00 1997 UT Obs. no.: 101
At 49x, a faint glow requiring averted vision, but seen unmistakably with it. Then some thin upper clouds cleared and it became a pretty easy object, glimpsed with direct vision. In trying to detect the galaxy's spiral arms I switched to 122x, and seemed to detect a condensation toward the middle of the object, with the dropoff in brightness being more abrupt on the S side.

Observed h2583, a 9th-mag. double star. Was an easy, faint pair of equal-brightness white stars at 49x.

A bright, blue-white star. Observed it at 49x as the first object in the "Galaxy Hop in Leo" in the April 97 Sky and Telescope. There was a bit of fuzziness around it, which I assumed was either dew on the mirror or the effect of high, thin clouds. Subsequent viewing confirmed the latter explanation; clouds came and went throughout the observing session.
