Object(s): NGC 6309
Category: Planetary nebula.
Data: mag 11.5 size 1.1'
Position: RA : DEC :
A tough one was this magnitude 11.5 PN. This one is easier to star hop and much
larger than NCG 6572, but a heck of lot dimmer. At 110x, itís exposed as
elongated dim smudge. PN was brighter than the 12.9 magnitude star
GSC5652:1465 that forms part of a square to the west of the nebula. At 146x,
the PN looked like 2 dim stars inside the PN. At 175x , the PN looks dimmer
now. At 220x, much dimmer, 1 (12.1 magnitude GSC5653:201) star now clearly
seen outside nebula to the north.
The PN is knowned as the Box Nebula, but I can't say I saw any "box" :-(.
