Sh 191 

Bob Hogeveen
Star: Sh 191 
Date & Time: May 10 2001 
Seeing: 6 <1-10 Seeing Scale (10 best)>. 
Location of site: Annen, The Netherlands
(53ºN, 6ºE) 
Site classification: Village backyard
Sky darkness: 4.5 (UMI)  <Limiting magnitude> 
Sky : Hazy, some thin clouds 
Telescope: Celestron C11 (11" f/10 SCT) 
Magnification: 200x
Harschaw's Scale: 2 <1 to 5> 
Unexpected a nice, I would almost say funny, double. This due to some more stars in the field : The double which is wide an bright at 70x and 140x with my CG11 is positioned at the end of a small horizontal, bit crooked, string of 4 mag 11 to 12 stars. The double itself has a vertical orientation (of course for the moment of observation). The impression it gave me was of a little snake with two fierce, flaming eyes.
While looking at it I noticed a patch of fuzziness just above the little snake, and indeed a galaxy (NGC5820) is situated there. All in all a pretty nice field.
With my 8cm f5.6 finder Sh 191 also shows well, but the body of the snake is almost invisible (as is the galaxy).

Star: Sh 191 
Date & Time: 12 May 2001 ( 22:40 UT )
Seeing: 5-6 <1-10 Seeing Scale (10 best)>. 
Location of site: Cheshire. UK
53° 15' N -2º 33' W
Site classification: Suburban
Sky darkness: 4.3 (UMi) <Limiting magnitude> 
Conditions: Nice clear night, looking good. 
Telescope: 200mm f/6  Newtonian
mounted over a Vixen GP mount (manual slow motion).
Eyepieces: 18mm Orthoscopic, CMG, X3.35 Barlow.
Magnification: X67, X322
I was drawn to this double star from Bob's description posted previously. 
Using X67 I found a very nice wide pair of what appeared to be blue/white stars. 
I could just make out the snake of stars leading to the double but I couldn't detect  the faint fuzzy as described. Returning later when Bootes had moved into darker sky I though I observed the faintest glimpse, using averted vision, of a few photons from a patch of light to the west of the double star. I wouldn't like to put my life savings on this though. 

Using the CMG at X322 an average of 3 measures gave a position angle of 343deg and a separation of 40.6sec. Very difficult to measure under the inconsistent seeing conditions.

A wide spaced pair,mag 7 and 7.5. The moon 
rather drowned out the companion, but I was able to see it. I did not 
attempt any measurements tonight - I don't think that it would have 
been possible to get any reliable ones due to the conditions.

Ambience: May 29 was pretty clear. I tried the technique of fooling those Commanche gods by waiting until good and dark to set up. Which seemed to work. Got a good alignment. The first quarter moon was near our choosen constellation, which could be a problem and it was rather windy. Since I didn't start until after 11:00, there were few if any porch lights on to interfer. No animals.
