NGC 3171 Galaxy *
RA: 10h 15m 36.7s Dec: -20° 38' 52"
Mag: 13.8 (P) S.B.: --- B-V: --- Size: 1.6'x1.0' Class: S0- pec

-71 is an easy to see good SB eg maybe 1' diameter and just off-round in PA 0. Brightens from very diffuse edges evenly and mod to the centre to a weak faint spot dead centre. ESO 567-28 is one field SW as a very tiny sliver of mist 40" x ?? that brightens weakly to centre and has very, very LSB. Mag 15 * at it's NE tip.

P.A.: 85 Inclination: --- R.V.: +3970 Source: RC3 *

this is a mod bright easy to see eg that is fairly small, seems to be round just over 1' diameter. Grows broadly and slightly to the centre without zones or apparent nucleus. There is a mag 13.5 * just a little off the halo, 30-40" to the SE.

P.A.: 140 Inclination: --- R.V.: +3700 Source: RC3 *

In a well populated field for Hydra with a lot of mag 9-12 *s. Small oval eg a little over 1' x 40" in PA 150 with a slight brightening to the major axis through most of it's length. Faint *ar nucleus. Good SB and easy to see.

P.A.: 82 Inclination: --- R.V.: +3880 Source: RC3 *

This is a beautiful little edge on spiral eg in PA 90 with a mag 14.5 *at the E tip, on axis. Maybe nearly 1.5' long hardly 10" wide in PA 90, LSB outer halo but a fairly well defined, slightly to mod brighter small well defined elong core/nucleus with a whiff of a stellaring at centre.

P.A.: 127 Inclination: 5 R.V.: +5707 Source: RC3 *

This is a small to very small very LSB eg found to the SSW by about 2.5' from a mag 13.5 *. Small 50" diameter halo growing broadly and weakly to centre. Has quite LSB, but can be held steadily with AV. Slightly elong in about PA 150.

P.A.: 113 Inclination: 5 R.V.: +1696 Source: RC3 *

This eg makes a small 2.5' a side tri with a couple of mag 14.5 "s to its SE and NE. Almost seems *ar at first glance but is slightly elong in PA 120 dominated by a very small somewhat brighter core zone that occasionally looks stellar. Seems about 1' x 40" in PA 120.

-76 appears in a very barren field, so few *s. Appears almost between a couple of mag 15 *s about 2.5' apart oriented N-S. A bit over 1' diameter, round, very diffuse edged and LSB growing slightly to centre with a hint of a very small weakly br zone dead centre -- seems to grow stronger with lengthened observation. Definite small, slightly br zone in centre. IC 3131 is 20' NW

IC 3131 is no more than a tiny spot of gossamer brightening slightly to centre about 15" diameter, round adjacent to a small trapezium of mag 13.5 - 15.5 *s immediately to its W.

These two eg are pretty close to each other, probably 4' apart with -85 in PA 30 from -79 and there are a couple of very faint mag 14.5 *s between the two. -79 is the brighter, both seem round, -79 slightly the larger about 40" diameter. -85 30" across -79 grows weakly to centre where there is an occasional very faint *ar nucleus and -85 is possibly weakly elong off-round in PA 30 with no evidence of zones or nucleus.

This is an exceptionally beautiful, V/LSB needle-like edge on eg in PA 0. A slender sliver of gossamer 1.75' x 5". the DSS shows a quite bright core but this is not really evident in the ep. A creamy coloured 8th mag * is 3' E that is somewhat of a distraction. Very low SB and took some time to see its full extent and not immediately visible at first glance.

Dealing with the NGC objects first -96 is certainly the dominant in a close pair with -97 all but invisible about 30" to it's North. -96 is interesting with what appears to be a double condensation. Seems slightly elong, about 50" x 30" in PA 45 and oval but with a small 10" dia slightly brighter core zone almost a sub-stellar spot. But there is also a very small stellaring in the SW of the halo 3/4ths of the way out to the edge in the opposite direction to -97. Skyview indicates this is the star USNOA2 0900-07132201 at mag 16.3.

-97 just to the N of -96 is a threshold almost stellar spot of gossamer with no structure visible.

One field E is the IC pair. 20' E of the NGC egs. These are both extremely faint and LSB egs with -25 slightly the larger and brighter. Both are in PA 45. -25 is 50" x 20" uniformly V/LSB. -29 is only 20" diameter and slightly oval in PA 45, almost at threshold and difficult to see. Intermittent detection with A.V.

These are two quite diffuse looking eg that are close and N-S of each other with -05 to the S. -06 is only 2.5' away N. Both seem round, or -05 maybe slightly elong in PA 30 -- it is 1.25' diameter grows broadly & slightly to centre without zones or apparent nucleus. -06 is a little smaller, 40-50" diameter, similar SB to -05 growing slightly to the centre without zones. Both have mod low SB.

Frosty Leo Proto-Planetary Nebula
IRAS 09371+1212
RA 09h 39m 53.96s Dec +11° 58' 52.4

http://en.wikipedia.org/wiki/Frosty_Leo_Nebula

From Wiki:

The Frosty Leo Nebula is a proto-planetary nebula (PPN) located roughly at 3,000 light-years (Davis et al. 2005) away from Earth in the direction of the constellation Leo. It is a spectral bipolar nebula. Its central star is of optical spectral type K7II, by itself called Frosty Leo. It is unusual in that it has an extremely deep absorption feature at 3.1 µm and is unusually located at more than 900 pc above the plane of our galaxy.(Bourke et al. 2000) Further, as of 1990, it has the only known PPN circumstellar outflow in which crystalline ice dominates the long-wavelength emission spectrum and the only known PPN with point-reflection-symmetric deviations from axial symmetry.

This Mag 10.5 PPn appears non-stellar at magnifications of x247 and above, but very small, only a few arc-seconds diameter and has a light-blue colour. No structure visible.

This is a small slightly elong eg in about PA 90, oval, maybe 1.25' x 30" growing from very indefinite edges without zones broadly and slightly to the centre. There is a mag 12.5 * just E 3' . There are several 5 egs in the next field E (next obs).
