This evening’s sky was a delight , even with the nearby streetlights shining, the Milky Way stretched far and wide overhead.
At about 11.00pm I grabbed my Swift 8x40 binoculars and planted myself in the front garden.
Thanks to an earlier collimation my new binoculars were spilling out sharp pin-point stars in all directions.
My Swift Auburon 8x40’s cost £15 at a local
bootsale, and I can highly recommend that particular model.
One thing is to always make sure that any
prospective binoculars have collimation grub screws.
These four tiny screws are easy to find (with
a magnifying glass!) and are necessary to properly align the stereo view you see.
Without the ability to adjust this double view, you will quickly go cross-eyed and relegate the binos to the dustbin!
For astronomy usage I would never
buy binoculars unless they have the four adjustment grub screws.
When I first tested the 8x40’s, I mounted
them on a tripod and placed Arcturus in the field of view.
I was rewarded with
a lovely view of Arcturus and what appeared to be its identical twin!
After a slight adjustment of all four grub
screws, the double image of Arcturus merged back into one sharp starlight
point.
Do they work?
Most definitely, so far I’ve had good
views of M13, M33, M31, M81/82, Kembles
Cascade, the Sword Handle and The Coat Hanger.
Plus, ambling through the river of the
Milky Way is a joy with those little 8x40’s.
