Description

Working on tilt issues with my WO 81GT last night (always something to think about and  fool with) I decided to go for an area with lots of stars, M3.  I tweaked and tweaked (what fun...not!) using a cool new adjustment tool.  Seeing and guiding wasn't great so I did 30 second subs, also hoping not to blow out the star color.  Certainly not an impressive image at this focal length.  A bit under sampled, so I aggressively drizzled in integration. Cleaned up the noise with Topaz.   Low and behold...I forgot how much I like clusters!   Just try to imagine the night skies if on a planet in there...well no life possible in these things.  And they are old...so why so many young blue stars?  

Posting to keep a record, no need to like or comment.

ps  - tilt solved!! version C;  just a bit to much backspace though acceptable.

ps2 - cool tilt adjustment tool Astrodymium Rotating Tilt Adjusters

Description: Stunning plate solving for PGC (principal galaxy catalog). With mouse over plate solving does not show, therefore, I'm including this as a version. Just unimaginable!
