Title: M27 test images last night.
Post by: JohnP on Jun 10, 2008, 16:14:29
Last night was a great night - perfectly clear, still & no dew. Wanted to test my new focuser. It works really well & is a worthwhile upgrade to my scope. Focusing is so easy now - I can do it one handed without the scope/ image jumping all over the place - it's great :-)

Anyway, I did an LRGB image of m57 (again) - still processiing this one & so will post later & also a couple of test shots of m27. I wanted to see difference between the CLS & Ha filter. Below are results. The images are only 4X120secs for CLS & 2X300secs for Ha so lots nof noise I'm affraid. I think difference is amazing - there is so much more detail in the Ha - including a hint of the 'ejector jets'..  CLS is top image (in case you couldn't tell.. :-) )

Anyway, need to give this a proper go sometime.

Cheers,  John

Well, John, they are so good, I would have thought they were longer exposures than that.
They are going to be so good when you have finished!

Great shots John, nice and sharp - that focuser must have made a big difference.

QuoteWhy am I allways in Wales when its clear.

And there's me asking myself - why is it always clear when you're in Wales ?

Lovely shots John.  It's very interesting to see the difference between the two.
