I opened up the pinhole cameras a couple of days early just in case they were set in the wrong position, and also to check if the wettest November on record had made its mark.  One pinhole camera unfortunately DID … Continue reading

Geminids tonight!

There’s plenty of clouds at the moment 🙁 but I’m hoping for just a few gaps in the cloud tonight.  No Moon – and it should be the peak in the Geminid meteor shower (13th – 14th December 2009).  Went … Continue reading

Inner space – again!

Well as the weather is not allowing me to take outer-space images, it’s back to some inner space work again.  This time an opalescent beetle leg gets photomicrographed using a 23-frame focus stack put together using the Helicon Focus software. … Continue reading
