Pleiades 1962 to 2019

A few weeks ago a friend gave me a book on astronomy published in 1962, in it was an image of the Pleiades. Luckily it was of a similar scale to my images, so as an experiment I overlayed and aligned one of my images with a scan from the book and it shows some stars that have moved in the intervening 57 years.

The alignment isn't perfect but the stars that move do so contra to others nearby so must be real. The image with the spikes on the big star (Alcyone) is from 1962 overlaying my image from 2019 with a 50% transparency. Play it full screen and take a look at the stars at the top, left of centre. Look closely and you'll see others that also seem to have moved.

Orion Nebula

First time imaging the Orion Nebula with 10 minutes subs.

The stacked image had the central bright region totally over exposed with no detail visible, so I blended an image taken with shorter subs to create this final image. 

Scope: Sky Watcher ED80 DS Pro
Mount: Sky Watcher CG4 motorised with modified controller for guiding.
Camera: Altair Astro Hypercam 183C
Guide cam: QHY 5L-II-C

12 x 10min Light
6 x 10 Min Dark
12 x Flat
12 x Bias

Stacked with DSS, finished with Photoshop Elements and GIMP.
