Late Rosette

First imaging session since Christmas- so a bit unfamiliar with my gear.....anyway first target was the Rosette rapidly dipping into the north west

My very next image was a re-framed version with longer subs.

Finally a 'messy' Jellyfish nebula- right in the corner of the DSLR frame (the image shown is a cropped quarter of the full frame), so the head of the Jelly is not well resolved.

I just acquired a 40d from a friend, hard to get used to the bigger body and buttons in different places. Seems to perform well!

The Canon 40D seems to work okay, I bought mine cheap second hand and did a DIY full spectrum mod (without re-fitting a further filter)

As you can see they pick up the H-alpha nicely and there's no need for the filter if using an all mirror (i.e. Newtonian telescope)
