Title: M51 Whirlpool Galaxy
Post by: Fay on Apr 12, 2008, 19:07:22
Last night I did this image. It was 9x300 secs, SX via ED80 cls filter, guiding DMK via WO ZS66.
I only had time to do 10 images due to cloud. I left out one of the images. The guiding is showing slight trailing, but today I re did the image omitting 2 of the subs taken in cloud & the guiding was quite good. It really needed double the subs, but I was happy that all was ok.

Don't like putting large images on, it is like sleep walking & going outside & realising you have no clothes on!     If you know what I mean.

Sorry Fay - lost me....  :-?


Nice image by the way - like you say could do with a lot more subs... shows good promise though & glad everything works after your disaster yesterday....

That's a good start Fay.  Get some more luminance data then some RGB and you'll have yourself a great image.

Nice Image Fay, ;)

Glad there were no serious problems with the mount, so keep them images coming.

That is kind of you Tony. I will add to it when weather allows.

Hi Fay,  Very nice image, well done.  I'm starting to realize just how difficult that Galaxy is to image.

Thanks ROBERT, I want to carry on with it, trouble is, with hardly any good nights, all the things we want to do, are mounting up!!!!!!

Could be a couple of good nights this week.

It was predicted to be clear after midnight and I woke to a clear blue sky.
