Observer: Ante Perkovic 
Your skills: Intermediate (some years)
Date/time of observation: February 8th 2004
Location of site: Kasjuni beach, Split, Croatia (Lat 43.5, Elev 0m)
Site classification: Suburban
Sky darkness: 4.5 <Limiting magnitude>
Seeing: 5 <1-10 Seeing Scale (10 best)>
Moon presence: Great - full or very near object
Instrument: 4.5" (114mm), F/8 (homemade dobson, "babydob")
Magnification: 25x, 48x, 79x
Filter(s): none
Object(s): NGC1817
Category: Open cluster.
Class: 
Constellation: Taurus
Data: mag 7.7  size 16'
Position: RA :  DEC :
Description:
25x: Just 4 * inside 10'  x 3' 
48x: The same 4 *
79x: And again... 4 *.

I'm not sure if this 4 * are in the cluster at all. The map shows me that cluster is 
slightly to the east, so those 4 can be just a few bright stars on the rim or not members 
at all.

I wouldn't even search this cluster if it didn't fit in 40' circle together with NGC1807 
(which also isn't  an eyecandy itself ).
