General Description

This run observes 2 different binary brown dwarfs in 2 different imaging
 OBs. In all Obs the science object should be clearly visible during acquisition
 and should be centered in the array. Since we chose the S27 camera in both OBs our
 science target will be the brightest object in the FoV.
In the FoV for the field selector (2' x 2') there is an even brighter object for
 OB 2MASSJ0310+1648, which is a galaxy with K=11.99. But its brightness is still
 in the allowed range.

OB names              	R (TTS)		target			separation	comments
--------------------------------------------------------------------------------------------------
2MASSJ0310+1648		16.91		K~ 14.2 and H~ 14.9 	47.16 arcsec
SDSS0423-0414           17.95	       	K~ 13.2 and H~ 13.4	44.72 arcsec	TTS is a
 galaxy

We know that the TTS for OB SDSS0423-0414 might be a little bit faint, but it's
 the only guide star within the permitted distance for a TTS. Since the sience target
 is very interesting its still worth trying.

The OBs: 2MASSJ0310+1648 contains 14 science dither points in each filter, SDSS0423-0414
 12 science dither points per filter. The goal is to stack together all images per
 filter to achieve the necessary S/N for a very good data reduction and correction.

Critical Observing Condition Constraints

Since the contrast and the resolution are very dependent on the ambient
 conditions, we ask the night astronomer to feel free to adapt the observational
 strategy (DIT/NDIT) to optimize the OBs.

Thank you for your cooperation.
