Someone mentioned a lack of rainbows lately. Here's one my wife, Lesley, snapped from the back door on Monday 12th I think! Bob

That's a fabulous photo. I can't say I ever saw a better rainbow than that myself & doubt I ever saw as good a double rainbow. Give my regards to your wife & congratulations for taking that excellent picture.

Yes, an excellent photograph of a rainbow, with all the extras on show... Secondary Bow, Alexander's Dark Band, Primary Bow (very brilliant!) and, if you look very closely you can also pick out Supernumerary arcs just inside the Primary. Regards maf.

That was two pots of gold for the lucky finder.

More great stuff. Your wife did an excellent job.
I got a quite few nice rainbow photos in travelling about Scotland last summer.
One thing that niggled me was, my variable focal length lens, even at its widest angle setting, would not quite cover the rainbows complete arc. On one occasion in particular, I actually took enough photos to cover the rainbows full width. Actually two photos would have been adequate. When I got home a week or so later, I thought of stacking two images together. Unfortunately I then realised I had moved my position quite a lot between taking the photos and could not align the images satisfactorily. I have considered buying a wider angle lens but it's not something I would use very often. Probably be simpler (& cheaper) just to take my future collections of (individual rainbow) photos from the exact same location.
Best of luck to both you & wife from Cliff

Hi Cliff,
I bought a complete camera, a secondhand Panasonic FZ72, as it was cheaper to get than to buy a 20mm lens for my camera.
Interestingly, the camera must correct for distortion as it is pretty rectilinear for a 20mm wide angle at its minimum equivalent focal length.

However, the camera is poor in poor light.

I think that the Canon SX60 or 70 may have a 21mm lens setting at the wide end.
Most cameras only go down to 24mm or 28mm equivalent focal lengths.

The Vivitar Series 1 and Cosina 19mm to 35mm lenses are quite cheap, but I think manual only.
Wide angle, at least on a full frame camera.

Regards,
David

Hi chaps, Lesley says thanks for your kind replies and asks me to mention that she just snapped it with her ipad camera, nothing fancy. Bob and Les

I think your wife puts her camera to some very good use. I'd be quite pleased to get such great results with any equipment I might get.
Best wishes from Cliff

Many thanks for your interesting comments and potentially very helpful suggestions. Unfortunately I seem to be at a time when I'm reluctant to get any sort of new tackle. I'm reluctant to lash out on anything I might not really use much & other reasons I'd rather not talk about.
Best wishes from Cliff

I have also decided to try to stick with the current instruments that I now have...although when I say this to my wife, Sandra, she says, with a certain tone of voice, "yes, you always say that!" and I think that she really doesn't believe me! I can understand her disbelief, but really it comes to the point when perhaps enough is enough, especially when the years begin to rush by at an alarming rate! Regards maf.

Tempus fugit. I'd like to get more use out of my 8-inch Newt, but it's a bit of a struggle trying to lug it to the back garden.
I need to make the tube assembly much lighter - switching from a steel to an aluminium main tube, or making a frame tube of some sort.

I showed Sandra what I had written here about stop buying instruments, and her suggestion was the perhaps I could call my 75th birthday the cutoff point and see just how long I could last not beng tempted. Eh, when is that then?...In a week's time! Regards maf

Despite both of us being in the "winter" of our lives Mike, we haven't lost the sense of wonder and, we might add, romance that astronomy has to offer.
Music and astronomy alone make life worth living. :wink:
