Oh yes - I can see that now, Jim. That's a good idea when trying to get close up images of 'skittish' subjects. Good advice again.

Lisa, I'm sure you will capture some great bird images with your 200mm zoom. You obviously know that cropping can substantially improve framing and impact of your subject as your flower images are superb. I know your bird images will be just as superb.

Some excellent images being shown here. I agree with Jim re the macro shots and using a zoom. I find a macro lens a bit limiting when trying to capture moving insects. My zoom focuses fairly short distance, I find it really useful for butterfly images.

Jim your bird photos are really good. My only comment( not a criticism) is the twig in the background is off putting. Perhaps next time you could tie it out of the way.

I know it sounds like nit picking but in bird and insect photography the background is everything. Nice out of focus background with nothing cluttering to draw the eye away from the subject.

Great images from everyone!!

Thanks Trev. I thought exactly the same regards the twig. Didn't notice or think about it when I took the shots, note to self...look at the whole picture.

You may've thought some of my recent tree shots looked a bit frosty, so here's one to serve as an antidote.

And a robin has started nesting just outside our dining room. I say 'a robin' but of course there must be a pair,, but male and female looking alike I don't know if we are seeing two or just one. In some birds the male builds a nest then invites the female along to join him, but I don't think that's the case for robins

I love the multicoloured bark! What an original image that is. The image of the bird is also outstanding - what vibrant colours and such a 'cheeky' expression on it's face.

Wow some lovely shots, I have to admit I do like wildlife, birds, bees, flowers so here are a couple taken in the garden. We appear to have a regular Woodpecker coming now. I have to wait and try and capture him, he is very shy so the shots are through the window.

Garden shots just a couple. The birds are fancy bird feeder bracket. The other is the corner of a wing of a butterfly sculpture attached to the fence.

Nice indeed, Trevor - love the interplay between the rusty butterfly wing and the aged wooden slats. Lovely textures.

Lovely images of birds, garden furniture and trees.
I've got a few tree shots - like using trees for framing shots, macro shots and back lit leaves.

Comments - Michele love your white pigeon shot - contrast with dark background and delicate shadow on wing, interesting posture. Trev your rusty butterfly - great example of a small detail making a good composition, with the wood grain complementing. Mark lots of super shots - like especially the UICM lights, the apple blossom, the liquid amber leaves (just discovered the tree is also call a sweet gum - there's a small one next to the gate near the boating pond in Castle Park), the gate in the flood making beautiful diamond shapes with its reflection, and the barn with the sinuous curve of the dry stone wall echoing the fell behind - well done! I agree trees can make great framing devices. (I initially misspelt that as farming devices, which is also true!) One of your tree shots reminded me of this one - looking up rather than looking down! (No not infra red this time)

And our robin is still busy - couldn't resist another shot of her? him?

Stop press - Ed - just had a phone call from ACS: my conversion covers the range 720 - 1100 nanometers, so does not quite cover hydrogen-alpha emissions which are apparently at 680 nanometers. Some cameras - but not Canons - can capture them in the visible spectrum. Hope that answers your question!

Mark, great set of images. Faves are tree in Yorkshire. Apple blossom and Hornby. One comment the tree in Yorkshire I’m not sure I like the vertical panoramic? I think I would like to have seen more of the stone wall either side of the tree?
Phil liking the Robin shots keep posting 👍🏻

Hi Mark - Your images are fantastic - lets us all know what we are missing being under lockdown like this. They really show the countryside at its best.

Phil - thank you very much for making enquiries about your IR camera conversion. I had a feeling that h2-alpha was just outside the standard IR conversion spectrum. Once again, thank you.

Interesting question about seeing the hydrogen line using Phil's infrared conversion.

As Ed says, the hydrogen line at 656 nm (nm = a thousandth of a millionth of a meter) is just outside the standard near infrared spectrum (750 nm to 1400 nm), which is what I would expect Phil's camera to see. However, I was interested in how Phil's camera worked - why didn't the red/green/blue gel filters in the sensor's RGB mosaic stop the infrared from getting through? The answer I believe is that the gel filters are sufficiently leaky that, though it is attenuated, a reasonable amount of infrared does get through (in all three colour channels). So, the lesson is that no filter has a hard roll-off, which implies to me that there is some chance of seeing the hydrogen-alpha line using Phil's camera.

How could this be tested? What is needed is a nice source of H-alpha emissions that doesn't emit lots of other radiation, e.g. not the sun. Apparently, astronomical clouds of gas are the place to look since these contain lots of ionised hydrogen. However, I am not enough of an astronomer to know where these things are in the night sky. If we could identify a constellation rich in gas clouds, then we could tell Phil which way to point his camera! Anybody know about these things?

Hi Robert - thank you for supplying the additional information re: Phil's IR camera conversion and operation. You are spot-on when you say the optical filters - especially the IR filter normally fitted to commercial cameras (hot mirror) isn't a sharp cutoff but has skirts that attenuate the signal at a predetermined rate. It would be very interesting to see if Phil's camera could see the h-alpha emissions.

I've taken some sky shots but in the absence of a star-tracker module the longest shutter speed I could use was 30 seconds and even then I was getting star trails. You need a longer exposure time (sometimes measured in 10s of minutes or more). Problem there is that with very long exposure times, the light pollution is overwhelming. Shorter times and higher ISO settings also give hassles (including increased noise in the image). We need to get well away from lights.

If you wanted to look for h-alpha emisions, there is a website - 'Night Sky April 2020 - Jodrell Bank Centre for Astrophysics - that has star and constellation location information showing you where to look for the different stellar objects You would most likely need a very fast lens to capture as much light as possible and most likely a telescope to resolve a decent image. Good luck! Love to know how you get on.

Nice night shot Ed good exposure and composition. You may have set a new theme running. Here's one I shot through our dining room window one evening

Thank you, Phil. Your image is very nicely framed. It seems almost surreal in the reflection of the table lamp superimposed on the vegetation. Quite striking is the apparent colour change in the leaves going from green at the sides of the image to being golden against the red of the lampshade.

Ed - I like the first one of these - the complementarity between the fresh new leaves and the stone and wood works well, against the blurred colourful background.
