Hi Guys,

found some data that i forgot to process. it is NGC1360 a faint but biggish PN. was taken 6/1/08.

Only got 3 x 5 minutes at ISO 400 as i remember, it was due west where my neighbours tree got in the way.

Love the gorgeous subtle green and blue colours in the nebulosity. Seen heaps of images of this wonderful planetary, but never the different contrasts across the planetary disk.

I think you will find the magnitude of the nebulosity is not 14th but is more like either 11.6v and 11.5B magnitude.

Considering the brightness of this object, it remains extraordinary that it was discovered so late by Lewis Swift in 1857. You should note that the central 9th magnitude blue star is not the central star of the nucleus, but is the one below it - being 11.35v or 10.96B magnitude.

The red star is RZ For - a semi-regular variable star, and is near maximum brightness at 8.4v magnitude. The blue star also makes a nice contrast - often not placed in the image field in preference to the planetary.

I really like this pic Eric.:)

Wished I had some data like that!!! nice work Eric. Must see if Scott as imaged it?

A good image for such short exposures.

I would go back to this object for more data in the future as there is a wealth of information such as the Ha emission on the right hand boundary of the PN not found in your image.

Also, and I hope I am not being picky, but the visual magnitude of the PN is around 9.4, not 14.0 as displayed in your title. NGC 1360 is one of the brighter of the larger PNs.

Regards

Steven

I agree with Steven the mag is about 9.4. It is easy to see with 20x80 binoculars.
Kent Wallace lists it as mag 9.6 and 460" x 320".

cheers guys thanks. I use starry night for my object info. it states it is mag 14.0 in it. I wish i can obtain more data but has done to west now where my neighbours tree has blocked it . till next year :)

You have done a lovely job on this one Eric. Nicely composed and nice star colors add nicely to the whole image.
cheers Gary

Although the object is quite difficult to catch, you've done great job ! I am just wondering - why do you shoot at ISO400 ? Isn't the dynamic range at ISO800 wide enough ?

thanks Gary and Ant. cheers. Shooting in ISO400 helps me with my noise and light polluted skies esp with 5 - 7 minute exposures.
