Observing Report,Planetary Nebula Ngc 6445+Globular Cluster NGC6440
31/08/11

16" F4.5 Newtonion


30mm eyepiece,mag x 60
Bright seems oblong shaped,12.5 mag star N/W 8 mag star S/E
UHC filter Much brighter,and gives some hint of a bipolar nature.
O111 darkens the nebula but the bipolar nature of this object much
more pronunced.

NGC 6440 in same field, Fov 60' small,round, brighter towards the middle,
some of outlying stars resolved.

Nagler 17mm type 4 108xmag
Bipolar nature of the PN plainly seen,O111 splits the two ends cleanly
but the UHC makes the object brighter.
The 8 mag star South East detracts the view and it is best to try and put
it out of the field.
Without a filter this is still a nice object.

NGC 6440 much larger and a greater number of stars ar resolved in the outer
regions but no stars resolved in towards the center.

6mm Radian 304xmag
Quite large with a lot more detail.
UHC gives the best result with the 13.3xmag star at at the South West corner
of the nebula plainly seen
O111 More nebulosity is seen,the nebula is narrower at the northern end but thicker
and broader at the south.
Is very good even without any filters under high mag.
A wonderfull Planetary to observe, takes magnification well

NGC 6440

More stars resolve but none to the core.
It is good when you can get two objects of a different nature in the same field.
Cheers:thumbsup:

Thanks for the report Ron, a very interesting pair of objects.

Wonderful report there Ron, thank you so much for sharing, and I apologise that it took so long to respond to it.

I went looking around for some pretty pics of those two objects, and I came across this beautiful pic..

Here (http://http://www.iceinspace.com.au/forum/showthread.php?t=77758) is a pic from our deep sky forum of the two objects in the same fov (taken by Steve35)

And I also came across some interesting reading here from the Cornell University Library, regarding NGC 6440. NGC 6441 mentioned in the article below is one of my favourite globs.

I just checked the links on my above post and NONE of them are working for me. Does anyone else see them? Seems strange that I can't see any of them. :shrug:

Edit: I've just changed the links and put in another one and removed the others, but still doesn't work. My links have gone on strike. :mad2:

[astroron]

No Suzy, I cannot see them either :shrug:

[Suzy]

Hey Ron, just to see if it's me or this site,
can you put a link of a pic to one of those objects to see if your link works?
Thanks.

Ok, it's me...
I tried typing in your link but it didn't work for me again, tho I could view yours when you posted it. :confused2:

Here is the link for that pic of Steve's on the forum, if you want to see it, you will need to copy and paste it. It's a goody!

I don't get it....
I didn't click on the link icon, I just copied and pasted that link into the post and when I hit "submit" it came up as a link. Mass confusion. :confused2::confused2::confused2:

[astroron]

I just tried to add a link for NGC 6445 and it wouldn't let me either :screwy:

[Suzy]

If nothing else, I'm making your obs thread look very busy with lots of posts haha. :P
