About Astrojohn

I am a science geek! Interests Astronomy, Skiing, Philosophy, basically any form of technology including writing automation software for my observatory. I will also share this with others using the same EQMOD/Astroart tool set.

Horsehead Nebular – Last night 150 sec X 3 per colour

M51- Good seeing and good target

My image of M51 in colour came out really well:

M51 Colour

Star trails looking for Meteor shower?


This is a 2 hour exposure with the star trails but no meteors??

11th August 2016 10:30 to 12:30

North East at 45deg

First images from the new observatory- Full Moon -some thin cloud.

M51 Galaxy

M51 Monochrome

Monochrome Veil Nebula.

Veil Nebula.


Next step is to get focus automated. Just need script..


Heart Nebula – AA5 Observation Manager 9.06 – 80mm Skywatcher..

I started trying to get a colour version of the Heart nebula but the cloud rolled in at about 01:00 and I only got the red channel.

So here it is 4 X 500sec plus 2 darks and Master red flat.

However, not as good as the other nights image?
