April15th: Sparkly Sirius

I've mentioned before that I'm fascinated by space and the night sky. Inspired by a post on Twitter a few days ago, last night I made an attempt to photograph the star Sirius (also called Alpha Canis Majoris or the Dog Star). Its name is derived from Greek meaning glowing, sparkling or scorching". Easily visible in the night sky currently lowish to the south in early evening, it's very bright (though not as bright as Venus at the moment). Of particular note is that it's probably one of the "twinkliest" stars in the sky, and even with the naked eye you can see both the twinkling and as well as some apparent changes of colour as it twinkles.

The collage photo below is the result of my efforts last night. The change in colours from this star are literally over a period of a couple of seconds whilst I took a burst set of photos and are both amazing and stunning in equal measure and are largely due to the light from the star combined with the atmospheric conditions as the light hits the earth's atmosphere. I'm dead chuffed with the result of this as my first effort at this.

I achieved result this by tripod mounting my binoculars (Olympus 10x50 DPS1 - excellent for star gazing), focussing on Sirius and then defocusing slightly (to get a more blurry and therefore deliberately fuzzy shot of the star) and then hand holding my iPhone XR camera lens to one of the binocular eye pieces and holding the shutter down for a couple of seconds to get multiple burst images. It's a bit hit and mis-using the phone hand held to actually get the shot, but after a couple of goes shooting nothing I managed it!

Once I got the shots, I needed to post-process them as the star was just a tiny coloured dot in each frame. I exported all the images from the iPhone, and then used software called "BatchPhoto"to import and crop all the images in one go so the crop ratio was 100% (doing them individually/manually would be a disaster). Then after exporting the cropped images, I used a Mac application (sorry - no Windows here), called CollageFactory Free from the Mac App Store to pull together the image above in a grid.

The night sky is truly a wondrous thing, and with the current clear skies and relatively mild evenings, it's a perfect time for getting out in the garden and having a look around. There are numerous people to follow on Twitter who provide all sorts of great info about the night sky, but if you only follow one I recommend @VirtualAstro (website at meteorwatch.org). One imminent thing to watch out for is the Lyrid meteor shower which occurs this year from tomorrow (16th) to 25th April peaking late 21st/early 22nd.

Back in the world of #isolation life and Covid-19, my son has somewhat expectedly been put on furlough. Daughter is still working from home, most of her IT issues seem to have been sorted, and my wife has a week off from work this week (well her normal 2 days anyway). She's been to see her Mum today and do some shopping for her - all ok there. After yesterday's nice walk over on the local golf course, the next highlight of my week will be a trip to the doctors surgery on Friday for my routine blood test.

I can assure everyone that the cat is fine, but living a pretty dull life currently. Sleeping most of the time, as evidenced by this shot of her underneath the rosemary bush next to the compost bin!

Spot the cat

Until tomorrow....
