Long Exposure of the Star Canopus

This is a long exposure shot of Canopus in black and white and I've adjusted the settings a bit to bring out more of the 'streaks' from the star itself. I had posted a while ago about this and have the original image there .

Taking this one was a bit of an unusual set up for me , as I normally just use my scope and my Nikon D5300 at prime focus , which funnily enough is a bit odd in itself because I have to take the focuser off my Newtonian because I can't get close enough to achieve focus with it on.

Anyway , for this image I had my Nikon D5300 , a Nikkor 18-55mm lens , a 42mm Camera Projection Eyepiece with my 250mm Newtonian (all of that was probably a bit heavy for my mount , an NEQ6)

The settings I used for this image were
Exposure of 72s
Nikkor 18-55mm lens @ 27mm (in addition to the 42mm eyepiece)
f/4 , ISO 400
Focal Length of the telescope : 1250mm

And below I'll post a few different versions of this image , with different settings applied. And I will post the original as the final image in the post.

A colour version. Adjusting the settings a bit brought out the star more , but gave the background a reddish tint.

And this is the same image as above , but I've replaced the background with the original image. Nice for the background , but still a bit of noise in the light surrounding the star.

And finally , the original image.

I should also mention , if you are interested in Astronomy , Space , Astrophotography ect , I would definitely recommend checking out both @terrylovejoy and @astrophoto.kevin . Both have excellent images on their pages and also have a wealth of information on the subject. Also , Terry has written up a Guide to Basic Astrophotography ( 11 parts so far) . So if you are interested in this sort of thing , these guys are definitely worth following :)
