Title: A Globular or two...
Post by: RobertM on Apr 21, 2009, 21:16:01
Well it is that time of year...

I picked the wrong target to start with, M53 and the faint NGC5053, I think these are the only pair of Globulars that I can fit in this field of view.

30 x 180s unguided, dithered via mount in MaximDL, Sky90@F/4.5 with SXV-H9 and Baaded Neodymium filter

M53 and NGC5053:

Had a few minutes to spare so I thought I'd grab an image of every Globular that was visible.  These are quick slew + a single unguided 180s sub each.  All the following have the same pixel scale and exposure so are directly comparable.

M92:

ok thats cool, so with the weather this week looking fantastic, I have to goto Preston!

I bet it will be nice and coudy by the weekend.

I think M3, M13 & M5 are getting well placed at the moment, so who will do the best one this week?  Not me :-(

Robert,

That's certainly a successful night's imaging!  They all look really good.

Thanks everyone.

Looks like you'll be in astro heaven next week Mac, I certainly hope you get some great weather.

Daniel,  The last four were only a single 3min sub each so it wasn't really too much work, in fact I think all four were captured in less than 20mins .  Once I'd worked out the sequence for one the others only took 10 mins each to process - no sweat for a change !
