A fairly tight pair which
I didn't split until I got to high power, where I got just a sliver of
black. The pair appears blue to me.

Date & Time: 17 July 2001 ( 21:45 UT) Seeing: 6+ <1-10 Seeing Scale (10 best)>. Location of site: Barreras, Salamanca, Spain. Site classification: Rural,Suburban. Conditions: no moon, fairly dry but with gusts of wind. Sky darkness: 5+, some light due to street lights in the village. <Limiting magnitude> Telescope: Meade 7" Mak Cas mounted on a Losmandy GM8. Eyepieces: 25mm plossl,12mm plossl and 7mm ortho Magnification: 107X, 223X and 381X Harshaw Scale: 2 <1-5; 1 best> |
Could not spit the double at 107X but had success at 223X and much better view at 381X. This is a close double of almost iqual magnitudes. Both white with a tint of blue. Rating 2 on a scale of 1-5 with ! the best. | |||

Date & Time: 21st, July, 2001. 21:00 – 23:05UT Seeing: 7-8 <1-10 Seeing Scale (10 best)> Transparency: 3-4 <0:worst -10:best > Location of site: Quintueles, Gijón, Spain. 43º 32N, 5º 55W. Altitude: 20 m. Site classification: Suburban Sky darkness: 3.0 - 3.5 <Limiting magnitude> Temperature: about 15º C Conditions: A lot of haze and moisture. Seeing is rather good, but haze actuates like a light diffusor and that makes difficult observe stars fainter that 10 magnitude. Humidity: about 90% Telescope: Vixen 102 4" achromatic refractor Eyepieces: 35, 10 and 5mm Baader-Planetarium Eudiascopics Magnification: 200x |
This double appears in a field of 4 stars with a rather open trapezium shape. Until reading with attention the list of doubles in Lyra I don't realize that Struve 2328 is almost hidden in one of these 4 stars. At 200x the split is clean and I think to perceive one of the components as orangish. | |||

STF2328 sits in a rich field.
Using 93x the view is very nice and the double is close but well split.
In the same FOV we find STF2327 (at 3' 45" due west), an average double (rating 3), but it does add to the field. No colors noted. |

Est PA without inst......070d
Primary .....blue-white Clean split at 112x. A single
equally bright star due west. This star is the primary of STF 2327
(19.4"/314d, mag 8.4, 12.4). The secondary wasn't observed.
A pair of stars to the north. This pair is KU118 (50.4"/323d, mag
9.1, 9.3). Three doubles in the same FOV. Some dimmer stars scattered
about.

(w/Ku 118 & STF 2327):
The hinge of a neat trio. STF 2328 itself was resolved at 85x, but it took
120x to tease out the 12.1 mag cpn to STF 2327. For the field, this is
a ***.
