Possible Variable Star Discovery

[dmill1220]

Darryl,
I sent a e-mail to that Euro agency trying to find out if they just used a dss1r band image as a base for the hubble inset.
its murky but that is what others are saying may be the case, another scenario is that the dss1r band 1956 image is a plate defect, and i have a hot pixel or an interloper but the odds of all that?
Pretty wild indeed!

Ozz,
Darryl has just sent me a shot with my star clearly visibile, but im waiting to here from him as to where he got it its under the general call for help posting.

[ozzmoziz]

good stuff i been looking everywere
even downloaded in starry nites dss update see if its there and its not

[dmill1220]

Thanks Ozz,
Please dont give up im at around 800 plus images that i have reviewed!

Ozz.
I finally found one in yahoo its a luminance shot but it shows in the lrgb,
no copy right info and no date given, I book marked the site and hereis the shot with the star circled in red.
what do you think?
Dennis

[ozzmoziz]

u have it with out the circle...:P

[ozzmoziz]

was getting milk just got back...man its cold!@!!

[dmill1220]

Ozz,it sure is its nasty out side!
did you see the star in the exact same position?

[ozzmoziz]

ya but its not clear don t circle it just repst it
