Object(s): NGC  1624
Category: Open cluster.
Class: OC+N
Constellation: Persesus
Data: mag 11.8  size 
Position: RA :  DEC :
Description:
An easy find. Using 106x shows a very small, extremely compact open cluster. 
Increasing the magnification to 138x, 5 or 6 stars become resolvable, no 
nebulosity was seen. Installing the OIII filter at 138x, shows bright 
nebulosity as the background stars disappear. Nebulosity is pretty large, 
roundish, edges are not definable. Best view was seen at 106x with the OIII 
filter installed whereas it showed possibly a tease of backround stars 
embedded inside the nebulosity. 
Nice object!
