Cool!  I've been dying to hear how the grasshopper cameras perform,

but have been afraid to be the guinea pig (well, my wallet has been

the fraidy cat, mostly).  Can you disclose the price?

I followed your recommendation from a while ago and put an old Meade

2" Nebula filter on my SBIG camera on my Megrez 80, for hoots.  I live

7 miles north of downtown Los Angeles (can see the 'scrapers from my

house), and I have no trouble imaging 13th magnitude galaxies with it

(though lately I've been having annoying jumps in guiding my Nexstar

that I haven't quite sorted out yet).

Hi Perry;

I mentioned that I used an IDAS LPR filter in the long winded  

description of the First Light imaging, and why I used it too.

HTH..

Milton,

Sorry, for some reason I though you were in Toronto!  Yes, Calgary  

is "up there"!

Since you must have become somewhat of an expert at dealing with  

anthropogenic (being

a geologist, you'll appreciate that adjective!!) light pollution,  

do you use any filters in your

work?  You may have mentioned them in other posts, but this would  

be a good place for

restating that.

Thanks.

Perry
