Cats Paw

Not my best everything didn't go well for this session I think my collimation was knocked out and focuser was not aligned properly.

Tried the ED80 piggy back as the guide scope for first time and I forgot to put the LP filter on.

Still not a bad effort Trevor, certainly very bright though, but most acceptable.

A few problems Trevor but quite a bit of detail. You look like yougot a bit heavy handed on the red and managed to clip the green and blue but by backing off the red the image is quite presentable.

Keep at it.

[TrevorW]

Cheers Leon and Doug I'll spend a bit more time trying to process it again. Without the filter on the red for very prominent as is noise and rightly pointed out Doug I clipped the blue and green.

Nice effort Trevor. You are certainly on the improve. The elongated stars on the top left are a result of the focusor or something is not square to the optical line. Are you using a better focusor than the standard one?

Colour looks good in the second image and good detail present. Well done.

[TrevorW]

Thanks Paul

The focuser is a JMI one with a home made adapter and may not have been sitting square.

Enjoy your trip and hope it's cloud free
