Blue Target For Filter Test?
It's getting close to 6 weeks since I was last able to use any of my equipment. A trip to the USA and other travel + weather have conspired together!
I now have a selection of UV/blue cut filters to test with the Trius on my TEC140. Assuming the weather will eventually clear I could use a bit of help picking the best target to test on. A few months ago I wouldn't be asking for help, but now I'm not finding anything particularly "blue" to image. My sky is limited (cannot see M45 or M35 for example) to just East of the meridian. From overhead to west is clear and to perhaps 30-40 degrees elevation N and S. Any ideas?
Thanks,
Peter
