Tonight was very helpful ... I got the footage to 15 sets plus two calibration stars in two hours. Which to my usual pace of work is a record time ... Data
As noted during the observation session:
A seeing of 4 / 5, the temperature between 25 º C-24, 5 º C and high relative humidity of 86%.
I roll up (because heat to a time ...) and I started to not let anyone sleep in 50-meter radius with the noise of the engines of LX200, although by 2:30 am as clouded as it was impossible to continue disturbing the rest my neighbors suffered.
Well, the first is FCS 1599, a fivefold. Introduce measures 3 of the 4 pairs.

We measure STF 2130, a couple hard to "portray". A low magnitude of its components, which are almost equal in brightness (5.66 and 5.69), joins the lack of separation between them. So in order to unfold photographically need a good seeing and implement integration times of the order of hundredths of a second. Even so, I had to enlarge the images with QuadPix and make use of sophisticated measuring tool Surface. STF 2130

I'm sure I do not imagine that the Dragon could have in their custody so many double and multiple systems ...
As I said, the Dragon is considered one of the "ugly ducklings" of the sky. And what a surprise he has given us ... The Dragon almost makes us given the amount Swan and beauty of the pairs that we offer.
The following list is STF 2146.
is a triple system confusing (or at least I think so ...)
me explain: According to the latest
WDS measurements for 1998 and 1999.
- The pair "AB" AP has a 225 and a separation of 2.7 "
- The pair" AC "presents an AP 233 and a separation of 89.2"
But seeing my shots, (which of course can show misidentified pairs) can see that having a partner, is what is considered the "C" and I would correspond to "B". Moreover, both the AP and the separation for this pair to give my measurements, coincide with what would be the steps to "AC" that gives us the WDS.
In short, if the problem is that I have not identified either the pair (although it would happen, that in a small area of \u200b\u200bthe sky so find another couple with similar actions) or actually what you are confused are points that determine the components of the system ...
there anyway I leave the photo, my proposed measures and identification of components.

Next victim, STF 2078 - STFA 30. Another system that gets it done! Indeed
are two systems that share components. Struve is seen that in reviewing the system expanded its catalog STF 2078, adding the components C and D "but keeping the measure to" A and B "to the original description of why the system has STFA 30 no measure for pair "AB". Another question comes to me with this system, namely with AP 18 ° which indicates the WDS for the pair "BC", as my shots and measures, there is a gap of about 180. "This difference may be because to the extent of" BC "is exchange the components? Or maybe I did not correctly identified?. We will have to check ...

The truth is that it complicadillo encouraged to get all family members in systems whose main components are together and are bright and the rest are of higher magnitudes. Trying not to overwhelm the first, we see the latter. The trick as you know, add many shots with little time for integration and the more daring, combined with other short shots long exposure. The following is
STTA 200 or 65 Drac 20h 02m 20.1sy AR Dec. +64 ° 38 '03 ". This is another system consisting of three components. The pair "Aa" to the 11.9 magnitude secondary has only been measured in 1905 and 1960. 27,025 current separation is more consistent with the 1905 (26.7 ") than with the most recent in 1960 (32.2 ").¿¿¿¿¿?????

STTA 151, another triple system with components of high magnitude, so much so that for the pair "Bb", only measured on 2 occasions, has not yet reported the magnitude of the component "b". According to the images, I think that may be around the 13.5 -14.0. STTA -=-=
