M27 The Dumbell Nebula


Stayed up late to see the interesting side of the sky again.
M27 The Dumbell Nebula in Vulpecula et Anser (The Fox and the Goose)
A little trailing (!) again but it's nice to have colour in the images again.

Arcturus

A picture of a bright star in it's field can look good- specially when there's a little colour.
In fact this pic is the result of some autoguider tweaking.
Unlike Pete R I haven't been changing the PHD settings, (yet) just tightening any mechanical flexure I can think of.

Dust Bunnies Galore

This is a lesson stating that you shouldn't get your dslr sensor in as bad a state as this one.
I know it's a picture of the daytime sky at f22 but those shadows still show through the scope or fast lens. I did get it commercially cleaned, and will probably do it myself next time.
The trick is not to leave the camera sans lens for too long, and when it is - point in down so the dust doesn't fall onto it.
