Antikythera mechanism

I'm sure that most of you good folks here will be familiar with the Antikythera Mechanism - the 2100 year old gear driven orrery like machine found in a ship wreck off Greece.
For those that only have vague recollections of this incredible device, it was a machine the size of a shoe box that could accurately predict where in the heavens to look for all the major heavenly bodies known at the time. It ...

June Report and Video

Due to the lack of dark skies during the week and cloudy skies at weekends, most of my images are of the Sun and Moon (not that they're that boring) but there's pics of Aquila and Cygnus showing some of the faint surrounding constellations.

Gravitational Lensing

MS0735_grav_lenskris.jpg
I was watching this doco on "The largest Black holes in the universe" on you tube in 480p resolution.
I noticed a very large distortion within the grainy low res image at 16:12 / 24:58 mins . It appears to be some kind of lensing effect or photo manipulation... Can you help me find out the answer ? Picture is at 16:12 / 24:58mins

Meteoroid in June Bootids??

I'm pretty new to stargazing, and although I watched the Geminids meteor shower, so I'm not a complete newbie, I was astounded this evening, when I looked up from my telescope (trying to get a view of Saturn) to see what I thought was a firecracker traverse the entire length of my garden and beyond. It left a huge smoke trail but vanished seconds later. Thanks to my astronomy app, I was able to see ...

Detecting changes in a nebula

Hi,

With the fabulous images that are now able to be produced, I was wondering if it would be possible to detect subtle changes in clouds of nebula gas and dust over long periods of time.

Thanks.

SLR / Telescope connections

I am wanting to connect my Canon DSLR EOS700D to my 10" Dobsonian SkyWatcher go-to telescope but it just occurred to me that if I do the camera sensor will be exposed to the elements. Is there anything I can buy to fit to the camera or T ring that will protect my sensor from contamination?

Thanks,

Keith.
