Pic below from last night of CW Leo - a Mira variable that also has a surrounding but exceptionally faint planetary envelope. Anyone observing this star :question:

With the strong near-IR emission from this star my pic shows a defocussed image compared to a 'nornal' star [inset] due to the lensed focal reducer in the optical train of my SCT - I've noticed this effect before for similar near-IR sources :grin:

Go to http://astrometry.net and submit your image for a plate solve and see what it is.

Thanks Rich - I found entering 'CW Leo' in Wikisky [=Sloan DSS] solves it ok ;)
