International space station 06/08/2015 23:03





Taken using a skywatcher 120/1000 mm & Canon 100d. I had my scope tracking the star which is just visible (Albiero) knowing the ISS would pass close by and set my camera to an exposure time of 1/1600 secs at ISO 3200 on continuous shooting mode to make sure I didn't miss it passing through my field of view.
I recognise now the ISO setting of ISO 3200 was too high considering the magnitude of the ISS here was a very bright -3.2!

Planetary Images 2015

Jupiter 02/02/2015


This was made using 10 images of Jupiter from 00:40 - 02:52 GMT on 02/02/2015, a few images are poor quality but it still shows Jupiter's rotation and Io's transit of Jupiter quite well.
Skywatcher 120/1000 mm, Neximage5, 2xBarlow.


Io is passing in front of Jupiter and Europa appears to the right in the last frame about to pass behind Jupiter. The Great red spot (GRS) is visible here too.


One of the images from the above animation.


Venus 12/10/2015


Venus at 50% illumination captured with Skywatcher 120/1000 mm refrator, 2xbarlow and Neximage5 camera.



Saturn 24/05/2015


Saturn one day after opposition which is the best time of the year to observe it whilst it is opposite the Sun from Earth's point of view, it rises after sunset and is visible throughout the night. It is also at its closest point to Earth when at opposition.



Perseid Meteor Shower 2015


Composite image of Perseid meteor shower 2015 composed of 6 x 8 second images captured with a Canon 100d at 18mm, F3.4, ISO 1600.

Perseid Meteor Vaporising!



Cropped animation of Perseid meteor just about caught in camera's field of view. 5 x 8 second images.

The Sun

The Sun taken in white light using my camera phone with herschel wedge, 120mm refractor, 20mm eyepiece and polarising filter. My phone camera doesn't show the surface detail very well.

Above it is a close up of sunspot AR2158 where the x class solar flare erupted from yesterday (big spot top centre of bigger photo).

Did you know the Sun has a rotational period of 25 Earth days at it's equator and it's apparent rotational period as seen from Earth is about 26.2 days due to our orbit around it.

Also it has different rotation rates at different latitudes taking 34 days to rotate at it's poles and an apparent rotation rate of around 36 days at it poles as seen from Earth.
