Back to Observing Reports Saturday, October, 9 2010, I’ve decided
to try Shot Rock. I met
Shneor and Gregg at the site. This
site shows a ton of potential, elevation 7600 feet and
excellent skies. It is on the
border of grey and blue on the Bortle light pollution map (The
location is actually about 10 miles east of the red pin). This site is about ¼ to ½
magnitude darker than IHOP. Here are some photos of the site.
Anyhow, straight to my observing comments from my night observing on October 09-10, 2010. Pretty much straight out of my notebook. All objects listed here are in my
downloadable observing guides. Enjoy and hopefully
you will try of these objects. Equipment used: 22” f/4 reflector with no tracking20mm Pentax XW finder eyepiece 12.5, 9 and 7mm Baader Genuine Orthoscopics 10 and 6mm Zeiss ZAO-II Orthoscopics 5mm Takahashi LE TMB 1.8x ED barlow Lumicon O-III filter
|
(22” f/4 at 184, 255 and 328x) – Considerably faint round glow with well-defined edges. Upon examination, the ring structure was picked up and held 100% of the time with O-III filter. The ring was detectable at 184x, but best at 328x. 100% direct vision with O-III and 100% averted vision without O-III. About 20” across. A 15th mag star lies 5” off the NNE edge and a 16ht mag star lies 5” south. |
|
(22” f/4 at 255, 328 and 383x) – Picked up as a very small faint round glow with diffuse edges. 100% direct vision with O-III and 100% averted without O-III. About 8” across. A group of four 11 to 13th magnitude stars bracket the planetary from the NW, S to E. |
|
(22” f/4 at 184, 383 and 690x) – Appears as a bright irregular glow, roughly 2:1 elongated. Slightly pointier to the SE. A magnitude 15.1 star is just off the north edge. Mild response to the O-III. 100% direct vision even without the filter. PA = 135° and 0.4’ long. Probably one of the brightest objects I’ve observed all night. |
|
(22” f/4 at 255, 328 383 and 690x) – Bright stellar object. O-III really brings it out. At 690x, it appears slightly non-stellar. A 9.6 magnitude star lies 20” east. |
|
(22” f/4 at 184, 255 and 328x) – Extremely faint round glow. Detected only 25% of the time using averted vision and O-III filter at 328x. About 0.5’ across. A row of 14th and 15th magnitude stars lies north to NE. |
|
(25” f/4.5 at 408x) – Extremely faint small round glow. Even surface brightness. Popped in and out four times. It passed the wiggle test. A 16.6 mag star lies just off the east edge. About 0.5’ across. Visible about 25-33% of the time. |
|
(22” f/4 at 383x) – Four very to extremely faint very small round glows in a slight arc appointed with a stellar core for each galaxy. The arc goes from west to east arcing northwards. Distance from end to end is 0.8’ long. |
|
(22” f/4 at 383x) – Unresolved mass, even surface brightness thin glow. PA = 60° and 0.5 x 0.1’ in size. A 15.8 mag star lies 0.4’ SE from the center. |
|
(22” f/4 at 184, 255 and 328x) – Faint thin glow with defined edges. Even surface brightness. PA = 60° and 2.0’ long. A bright triangle of 11th magnitude stars lies to the south and east, with one just east off the NE tip. |
|
(22” f/4 at 184 and 255x) – Faint thin glow with defined edges. Seems to be more defined on the west edge. PA = 135° and 1.1’ long. |
|
(22” f/4 at 184 and 255x) – Considerably bright thin glow with a brighter round center. PA = 75° and 2.3’ long. A very faint star is just on the north edge of the center. A 16.2 mag tar is 0.5’ north from the center. Nearby galaxy, Mkn 1071 (PGC 11937) lies 2.6’ SSE and is a faint round glow with well-defined edges. 0.3’ across. |
|
(22” f/4 at 184 and 255x) Low surface brightness thin glow with defined edges. No central brightening. PA = 15° and 2.2’ long. |
|
(22” f/4 at 184 and 255x) – Very thin considerably bright glow with diffuse tips. Slightly brighter slightly elongated center. 1.3’ long, but diffuse tips take it to 2.2’ long. PA = 30°. A 11.9 mag star lies 1.6’ west of the north tip. |
