NGC/IC Imaging Target Calculator

[m37]

Hi all
 
I was messing around with the NGC/IC data from this excellent site http://vizier.cfa.harvard.edu/viz-bin/Cat?VII/118 in order to select some targets to hunt for. I ended up putting together a spreadsheet that lets you plug in the details of your imaging setup then calculates what % of your chip's horizontal size the widest part of the target occupies. You can then sort or filter as you wish e.g. all open clusters mag 8 or brighter that will occupy >30% of my DSLR chip with my f4.72 scope yields the following list of targets:
 

 
Attached in XLS format; there are some gaps and possibly some errors but it gives you a general idea.
 
Oh and in the NAME BOX (top left next to the formula bar) you can select 'data' from the dropdown to quickly select all the data for filtering/sorting.
 
cheers
