Images from Observing Session on 29 June 2018

Hello Folks,

This is my first blog post so apologies if I break any rules!

Several folks made kind comments about my imaging setup at last Friday’s meeting; It’s a Skywatcher 150PL on a HEQ5, I was using a ZWO ASI120MC camera (colour) with an x3 barlow and an atmospheric dispersion corrector (ADC). The filter wheel was just set for a an IR cut filter. The ADC has a pair of prisms and is used to correct the ‘blurring’ caused by the low angle of the planets at the moment – I’m still getting the hang of it.

Seeing and transparency for Jupiter was very good, but Saturn was less good and I only got one decent run before it hid behind a tree…

Mars came up and I spent about an hour on it, my first try of the year. Unfortunately my EQdir lead blew up (literally!) and although the mount was tracking it was drifting a bit and I  had to target manually which was ‘challenging’. The imaging runs when it was low down were awful, especially as it took a while to get the ADC dialled in with my attention more on keeping the red blur on screen! The final image shows next to no detail, but all other images form that evening are pretty low on detail 9although some are a bit better than mine). This is because of a planet-wide dust storm on Mars, hopefully it will die down before opposition in about a month.

The good news is that mount and computer survived the exploding dongle and an off the shelf USB-serial dongle was easy to wire up as a replacement.

Thanks to all RAG members for making me feel welcome, and giving me some really helpful advice and assistance.

Venus and Jupiter conjunction 13/11/17

Took a yomp over the fields on monday morning to get a clear eastern horizon just after 6 am, as I was setting up Venus was rising through the early morning glow a scintillating red spot light. All images taken Canon 450D on tripod with cable shutter release. All shot in raw and processed in P.S.6

Having taken images , quick dash back home to get off to London, hence delay in processing!

First image 18-250mm Sigma at 87mm ISO1600, F22, 1″

2nd image 180-500mm sigma at 500mm ISO1600, F22, 0.25″

3rd image same lens as image 2, at 180mm, ISO100, F22, 2″
