Today’s EPOD is the 3-D microscopy version of the Cabbage White Butterfly Eggs photographed by yours truly and turned into a stunning 3-D image by Dr. Brian May.

Brian made a suggestion as to how you could get an apparent baseline under a microscope to be able to make a stereograph – and as you can see the technique worked!!

I am now able to make 3-D images of anything I photograph through the microscope.  In addition of course, each of the 2 images is also a stacked focus-stacked image using Helicon Focus in order to get the depth of field.

One night before full Moon I managed to grab this with the 2 x 200mm and 2 x M26C OSC CCDs.  12 x 10-minute subs in all.  Came out much better than I was expecting so I must go back and do this again without a blazing Moon in the sky 🙂

In order to keep my hand in the HSF world, I will be making a batch of high-speed flash units that will be available early 2016.

Talking to a number of professional users I have decided that the specification for the new batch of units will be:

  1.  Light output power 75 Joules.
  2. Light pulse duration 25-microseconds (1/40,000th of a second).
  • Recharge time less than 5 seconds.

The units will be powered by a 12V dry battery pack (supplied with charger unit).  Estimated cost of a flash unit, battery pack and charger is £2,000 plus VAT at 20%, plus p&p.

Let me know if you have an interest in this equipment.

A very rare beautiful clear Moonless night last night so I put the 2 x Canon 200mm lenses on a favourite star region of mine – Kemble’s Cascade in Camelopardalis.

Managed 2-hours worth of 10-minute subs with the array and I added in a 2-frame Sky 90 image from a while back.  Result below 🙂

Please look under the “Courses” heading for a brand new course available from today.

This is the “I have been given a telescope for Christmas and I don’t know what to do with it” course.

Get up to speed with one-to-one tuition from Prof. Greg Parker at the New Forest Observatory 🙂

Managed to get 8 x 30-minute subs last night with the 2 x 200mm Canons and the M26Cs, and I added this to earlier 19 x 15-minute data from the same rig using Registar.  This is the result.  I think I will consider this one done now.

Another nice long 6-minute ISS pass tonight at 10:04 p.m.

As you can see, there was thin high cloud about which thickened considerably – so no imaging for me tonight 🙁

Another 6-minute long ISS pass from last night.  The earlier 21:41 pass was completely clouded out.

On the night of the blue supermoon (31st July) I looked out of the window to see the ISS passing over the Moon (so I missed a great photo-opportunity) around 10:00 p.m.

I hadn’t been keeping an eye on the ISS pass times lately so the same evening I took a look and was surprised to see that there were long 6-minute passes on just about every night of the following week 🙂

So on the evening of 01/08/2015 at 10:33 p.m. I was ready and waiting outside with the Canon 5D MkII and the Canon 15mm fisheye lens.  Beautiful long 6-minute pass.  Also there will be 2 tonight at 9:41 p.m. and 11:17 p.m. so I am hoping the weather will be kind.
