Re: [APML] ESO456-38 was Another one from New Mexico

["John C. Mirtle" <spampit@shaw.ca>]

Aha! The gauntlet has been thrown..... As it turns out, I do have a whiff of
this globbie. I haven't really paid attention to ESO globulars before but
now they have got my attention. I show ESO456-38 as mag 9.9 and about 10 arc
minutes across - very much like the Palomar globulars. On my full-rez tech
pan shot, I do have a clump of stars in a small square of stars, exactly as
plotted. It looked like more of a cluster to me than a glob, but even an 8
year old image can still hold surprises. :-) The full rez crop is at
http://members.shaw.ca/astrophoto1/files/n6520a.jpg and I must warn you all
that the stars are a bit blobby. Please bear in mind that at it's highest,
this is only 14 degrees above the horizon for me.
    As for 400F, all my experience was from one roll - perhaps it was heat
damaged or a little bit funky. Based on the results of APML'ers, I will give
it another try - after my Supra 400 is gone. :-)

Hi John,

<-snip ->
Thanks very much.  I haven't noticed the problem with P400F you mention.
If it's there, it's probably masked by my processing stumbles.  I'm
going to keep shooting it, along with E200.  I'd especially like to get
a shot of the Cone region, IC405, and the Seagull with this film, but I
was clouded out on those targets this winter.  So far, I find that with
my equipment anyway, 400F seems to excel at targets that have both red
and blue components - the M8-M20 I posted recently, the Antares region,
and a couple of others.

That's good resolution in 6520!  Interestingly, Uranometria shows a
globular cluster, E456-38, that's just west of B86 and is about as large
as the combined field of 6520 and B86.  I can't see it in either of our
shots, so I'm wondering if I'm just missing it amongst the star cloud,
or if it's a background object that can't be readily distinguished from
the cloud with amateur instruments.  Any thoughts on that one?

Sincerely,
