I’ve had some fun reading about this galaxy NGC 1600 and annotating the above photograph with information. This image is from my standard nightly survey of galaxies and as such is only a brief 5 exposures each of 180 seconds in length. I hope you enjoy the representation with additional information about NGC 1600. Some of the information was gleaned from this interesting article on NGC 1600 by Smith. et al 2008.

Below is the plain image without annotations where you can see the galaxies more clearly perhaps:

Karri Forest – Tree

Karri Forest - South-west Western Australia (Pemberton).

Karri Forest – South-west Western Australia (Pemberton).

Looking through my Karri Forest gallery you will probably find very similar photographs to this from 8 odd years ago, probably taken with film! But the fact is I never tire of this kind of Karri Forest photograph, and never tire of the Karri Forest its self. The dripping wet, smell of the rich muddy dirt and composting leaf litter, sound of light rain in the canopy, and a world of amazing photographs everywhere you look.

Picture Perfect

Picture Perfect - Yornup, Western Australia. Amazing green grass, winter sunshine, water, trees, fences .... what more could a photographer want? Back in July on our short trip down south. Tack sharp and oh so crystal clear.

Picture Perfect – Yornup, Western Australia. Amazing green grass, winter sunshine, water, trees, fences …. what more could a photographer want? Back in July on our short trip down south. Tack sharp and oh so crystal clear. This was one of those times when the lighting, lens and camera just work perfectly to achieve optimum sharpness and clarity.

Comet Stuff!

Recently I have been conbritubting many hours of photography to the global effort of documenting and characterizing the comet C/2013 A1 (Siding Spring). This comet will be passing very close to Mars in October. Observations of this comet are useful to agencies such as NASA who have hardware orbiting Mars. Today I published a fun little video of images from just one night, the 24th August. You can see it at Vimeo below.

See this and more galaxies in my galaxy gallery. This is probably one of my better LRGB galaxies to date, not something I do very often (LRGB imaging). To view a plate-sovle of this image which shows the objects in it (when you hover your mouse over the image) see it on my astrobin accounthttp://www.astrobin.com/113009/. It will also show you where in the sky this galaxy is located.

Sunspots – August 9, 2014

Sunspots – August 9, 2014

There are some nice sunspots with extra surface detail surrounding, today. This photograph was taken using my Megrez 90 APO telescope, Canon 6D, Tamron 2x teleconverter, Kenko extension tubes (between 2x and 6D body). It’s a stack of 470 frames recorded using Backyard EOS. A Baader white light filter was used (never look at or photograph directly at he sun without a safe filter).

My wife and I have spent years crawling around the understory of Karri Forests in the south-west of Western Australia. Back in 2000 – 2010 we regularly visited the area every year, amassing quite a collection of orchid and fungus photography. It’s amazing what you find, and you always find something new. People drive, cycle or walk through forests for hours and not see a single interesting thing, but if they just stopped and sat down for 10 minutes in the one spot they would be amazed by how much is within 1 square metre of themselves.

Since 2010 we haven’t done much in the way of macro photography in the Karri Forests, so a recent trip, in the brand new age of modern digital cameras, resulted in some macro fun on level of photographic quality which was significantly hard with film photography in the early 2000’s, but which is now quite achievable. The above two photographs are some nice glowing examples. The fungus appears to glow in it’s surroundings, semi-translucent and brightly coloured almost like a neon sign. And yet you can be assured most people still walk past these.
