Palomars Project

The Palomar globular clusters were discovered in the 1950s on the survey plates of the first Palomar Observatory Sky Survey (POSS). Several of the Palomar globulars--including Palomar 6, Palomar 7, Palomar 9, Palomar 10 and Palomar 11--are nearby clusters of average size that just happen to be heavily obscured by dust in our line of sight. Others--including Palomar 3, Palomar 4, and Palomar 14 --are giant globulars that are very far away in the extreme outer halo of the Milky Way. Although the objects vary greatly in degree of difficulty--from easy to nearly impossible--observing the whole list is a very challenging observing project for owners of big scopes (Wilson, Snyder).

The Polamars will pose a serious challenge. It will take exception skies, preparation, equipment and a good amount of coffee.

5/24/09 04:01 UTC   Pal 1 GL Ceph  2.8' 13.7 VG  4
Visual Description This is one faint globular cluster. Low magnification did nothing to bring this object out. HM did help, but this is an extremely faint globular cluster with low luminosity. It took some imaging to really coax this extremely faint GC. This GC has an irregular loppsided appearence to it. A few stars were resolvable...but very few.

Visual Description

Spent a good amount of time in preparation for viewing this object. Trying to get the correct coordinates and maps for locating Pal 2. Having spent a few night vieiwing this object I can say at least now I am more than somewhat sure that I have found and observed Pal 2. Located next to a double star...the star field seems to match all the maps and coordinate information. Using both direct and adverted vision I have been able to catch it...sometimes poping out and sometimes right there. I have even used some tricks like jiggling the scope and slewing back an forth to make sure that the object is there. Object also seems to be at the instruments limit in conjunction with the sky conditions of visibility. I am hopefulyl going to revisit Pal 2 within the next few days to reconfirm the observation.

Recomfirmation of Palomar 2 Aug. 28, 2009, 03:01 UTC

Nice looking glob...easy to recognize...nice classic looking globular. At low mag (125x) has a faint comet like appearance. Overall mottled with about a dozen outer halo stars resolved with higher power (350x). Central core brightening...sits just off to the side of a pair of stars of somewhat equal brightness.

4/27/09 01:34 UTC   Pal 5  GL Ser  8' 11.8 VG  5+
Visual Description Very sparse looking globular cluster. At best just a loose sprinkling of stars. Unimpressive looking globular cluster. Able to image object. My first Palomar to be imaged! This alone is a feat!!!!
5/25/09 00:30 UTC   Pal 6 GL Opu  8.3' 11.7 VG  5
Visual Description  At low mag. Pal looks somewhat nebulous and cirdular. This GC is embbedded within a very rich starfield...so you will need to be careful when looking for this one. Higher mag. does help to bring out some resolution of stars within the neblosity. The GC is also somewhat diffused overall. Imaging this object did help to bring out many resolvable stars wtih the GC. The SSC is XI.
4/28/09 01:23 UTC   Pal 7 GL Ser  8' 10.3 VG  6+
Visual Description Easier than I thought this was going to be. First attempt at this object (Pal 7). Wide field image is graphically better that the HM image...some star drift and elongation of stars. I am still satisfied overall. Pal 7 is loose in appearance lacking a concentrated central core. The coordinates that were supplied through Barbara Wilson earlier research were right on...no adjustments of any type were needed. Pal 7 seems at least visually to be somewhat richer than Pal 5 (being somewhat more sparse in appearance). At this point in time I would say that Pal 9 is the easiest, Pal 8, Pal 7 and then Pal 5 in order of difficulty. I have been using Deep Sky Browser and SED's and Barbara Wilson's site(s) as my main sources of information on the Palomars.

Visual Description

Finally. With a good month of planning and few failed attempts due to some incorrect coordinates…I’ve got my glimpse of Pal 8. The time spent planning for this observation paid off. First, I can’t stress the importance of planning and the collection of information…especially the observational reports of others who have actually had the opportunity to view these objects. From these reports I was able to get a feel for what I was looking for…it help greatly with the objects identification. Also, the downloading of photographic plates of the GC region helped prepare for what the actual star field (FOV) would look like…and it did! Pal 8 is similar to NGC 6540 in the sense that it looks like a faint warm glow that sits just above the background. I was actually surprised at the size of Pal 8…unlike its neighbor Pal 9 which is somewhat small with a bright central core region. Pal 8 was quite large with no brightening of its central core region. Somewhat easy to detect with direct vision (though one could easily pass over it) adverted vision did help to bring out more of the GC. Through the 16 inch it appeared somewhat oval with the objects brightness evenly diffused/distributed throughout the GC. The 12 inch did show the GC but just barely. At this point in time I consider Pal 9 as the easiest of all the Palomars with Pal 8 coming in second. Another important factor with these observations is the problem with dealing with the encroaching light pollution for the central Florida/Orlando area. Observing Palomars require dark stable skies.

Again I was able to capture Pal 8 with little effort. The image came right up on the first attempt. Pal 8 is somewhat more condensed in its central core than Pal 7 and 5. Having visually seen this GC previously it was nice to be able to also image it. This GC is located in an area rich in stars...good maps are a must. Also coordinates provided by Barbara Wilson's earlier research found the cluster to where it was supposed to be.

7/25/08 11 EST 6717 Pal 9 GL Sag  3.9" 9.2 F  2
Visual Description
Extremely easy to locate. Pal 9 poses the least challege out of the group of 15. Located in a small field of stars in the handle of Sagittarius. Able to resolve a good number of the stars within the cluster. I was suprised that it was not washed out by the nearby star (Nu Sagiti). Don't let this one fool you as the rest will truly test both your eyes, skill and equiptment.
5/22/09 02:00 UTC   Pal 10 GL Ser  4' 13.7 VG  5
Visual Description Pal 10 is definately a faint one. The LM did not bring out this GC. HM did though! Located in a somewhat busy starfield. There are a few brighter stars that sit with Pal 10 and do help to wash out this globular. This GC also appears irregular with some stars being easily resolved. I was able to image this GC.
4/29/09     Pal 11 GL  Aqu  10 9.8  VG  6+
Visual Description Faint and not as well organized at Pal 8, 9 or 7. Somewhat easy to image on my first attempt. This GC is not as sparse as Pal 5. Where as Pal 5 is almost non existent, Pal 11 is easy to identify as a cluster...could easily be mistaken as a galactic open cluster.
5/7/09 03:45 UTC   Pal 12 GL Cap  2.9' 11.7 VG  6+
Visual Description Visually not much to see other than a few faint stars located next to a triangle of brighter stars. Very loose with the feel of an open cluster. No overly difficult to see...but dark skies will help...still I was able to image this GC even with a moon at 90 percent full.
7/18/09 03:02 UTC   Pal 13 GL Peg  .7 13.8 G  4
Visual Description This is my second successful attempt at Pal 13. My first attempt just barly revealed the cluster at HM. This attempt did reveal a more than a half a dozen stars. Visually just a sprinkling of stars at the higher maginifcation. Also the imaging this time around picked up more of the clusters stars. This is one tough, faint object to capture. See image 
8/10/09 22:32 UTC   Pal 14 GL Her  2.5' 14.7 G  4
Visual Description Not visible on a low power sweep (135x). Higher mag brought out a sprinkling of a half a dozen cluster stars...very loose overall...no central core...visually it looks like an open cluster at best.  Need the best of skies...this is the one that will test your skills and scope. Some last quarter moon interference.
6/22/09 22:49 UTC   Pal 15 GL Oph  3.0' 14.2 VG  4
Visual Description Extremely faint cluster located in Opuiuchus. Very difficult at the lower maginifcation...though conditioins were not great. Higher magifnication did bring out some faint stars within the object. Very sparse at best. See image
