This morning's conjunction

Up at 6am to try and catch the Mars/Jupiter conjunction.
Didn't fancy spending the time out to do an alignment, so this is using a 102mm f/12.7 Mak on an untracking mount.
1s exposure at 1600 ISO

Plato and Mountains

A fairly high moon on the 27th December yielded some good photos, but cloud soon rolled in.
This is the crater Plato, which can show details inside the crater, but sometimes doesn't. At one time people believed that there must be occasional mists inside the crater to account for this. That now seems unlikely, but for some reason this time no detail appeared. :o Contrast that with ...

Slow moving object 17th December 2017 Slow moving object 17th December 2017

Can anyone help identify the slow moving object I captured on 17th December? The attached star trail image was constructed from about 2 hours of 15 sec exposures taken at 30 sec intervals. I was hoping to capture a few late Geminids meteors, but instead caught the slow moving object at the top right of the image. At first I thought it was a stuck pixel, but it first appears about 1 hour into the ...

The Crab Nebula

I find the supernova remnant 'Crab Nebula' difficult to see through a telescope, let alone image. It is fairly small too. I managed 10 x 1 min exposures using the ZWO. Each one barely showed a grey oval. However stacking them, and using a bit of processing brought out this image.
The exploded star's atmosphere has been reduced to these filaments which are the inner part of the nebula, and can be seen in ...

Orion Nebula - multiple exposures.

One of the biggest problems with the Orion Nebula is the very bright centre, and very dim periphery. A single exposure exposing the tenuous whispy exterior means grossly over exposing the trapezium and the neblousity around it. A good friend of mine, Chris from Alabama, USA, explained to me how some people have taken different exposure times and then nested the shorter exposures inside the over exposed parts of the longer exposures.
So on the ...

Cone nebula/Xmas tree

Hi all I managed to take this image last week aslo I checked on platesolver and this is the details it gave me which were Christmas Tree cluster,NGC 2264,The star 15Mon.I used this image and platesolver gave me as the image by using sdss on their system as an experiment.I thought I would share.Thanks for looking.I did the first in black and white and the second in colour,also did the third image in Hdr.

Triangulum Galaxy

Having tuned up the tracking on the 11" telescope, I thought I would try once again to image the Triangulum Galaxy. It is a large object but very dim. I got 8 successful and reasonably sharp 60sec images.
Stacking them yielded this image.

For simplicity I used the Canon, and had a go at training the mount for Periodic Error Correction, which seems to have helped. I would probably have done better with the ...
