I nearly missed this one as an early peek had the moon behind a neighbouring house (or, possibly, cloud).


Partial lunar eclipse | A7 III and 500mm AF reflex

A single shot, handheld, using the APS-C crop setting to get up to 750mm ... in fact I'm astonished that I can do 1/1000s / F8 / ISO 2500 at approaching midnight (23:20) in order to do just that.

Is yours rotated, Mikey? To my naked eye the half-moon effect was decidedly horizontal, as seen here. OTOH, is there really an 'up' in this kind of photo?

Lonsdale50 - Jupiter is indeed a frustratingly low-in-the-sky target. I've more or less given up (happy to wait a few decades until it is higher up! - Astronomy is definitely a game of patience)

While you save up for a tracking mount (don't go in cheap like I did, save up and get a HEQ5 or better, straight away) why not have a fiddle with this kind of image in photoshop - see if you can separate the colour channels and manually align them yourself.

And keep looking for the Great Red Spot.

Tonight, I saw Saturn through the telescope - amazing to see but I could tell it would be almost impossibly hard to photograph through all the shimmering haze...

Roll on winter... :-)

    We had a partial lunar eclipse here today and amazingly, the cloud broke up a bit. (what are the chances of that????)

    Now, I'm supposed to be using my 90mm Macro as part of the July Prime Challenge but the results from me aiming the camera+lens down the eyepiece of the telescope were amusingly bad, so I cobbled together a quick and dirty A-Mount/Telescope adapter and mounted the A99ii directly onto the telescope.

    I normally use my specialist astro camera for this sort of stuff and stack 1000s of frames. In this case, it just wasn't practical for a variety of reasons, so here's the result of stacking 20 A99ii shots through my 200PDS (1000mm) scope

    Partial Lunar Eclipse



    At first glance, it just looks like a 'normal' half moon but coloured orange. But look a little closer - the rest of the moon is way more visible than normal... I just wish it was a little sharper but this moon appeared very close to the horizon with plenty of atmospheric disturbance...

    Hi Sashi;
    Sure, happy to share w all members

    What I found impressive was how sharp that little lens is. I bought it specially for the shoot


    Here's one I call "The Heart"





    this one is for a little context

    Here's the whole album

    I took a chance and the stars lined up in a near Life Changing experience. I found myself in Natures Cathedral

    Most impressive is the fact that you were at 10,000 ft!
    Could I see the color one as well, please?

    As jupiter is low in the horizon (13deg) at my northerly location there is lots of atmospheric dispersion. This results in the color fringing which I couldn't all get rid of with registax. For where I am, Jupiter's altitude is only meant to get better (higher) by 2023!


    I'm not the arbiter of what's allowed/disallowed, but many or even most of the astro shots are composites, and video work still involves photographic skills. I think as long as the post is a 'still' image, it's probably legitimate for Dyxum. And you used A-mount equipment.

    For my part, I think you did a fine job with the image under challenging circumstances and with limited gear.

    For my own (still-shot composite) feeble attempts at Jupiter, I found it helped to use different exposures for the moons vs the planet, then combine (but I did not have access to video). I mention this as a possibility you might or might not want to explore.

    Thanks for the encouragement. Definitely not as artistic as your wide angle astro shots - I think I need to get a tracking mount before I progress onto those (and find somewhere dark!)

    Jupiter with Europa & Io



    Just really showing what is possible with Minolta 500mm reflex (plus Kenko 1.4x stacked with Kenko 2.0x) - on Sony A7M3 (via LA-EA3). Settings were 1/20s SS, approx f22, iso 800. I had to turn on APS-C mode plus Clear-Image zoom at 1.5x to at least get something discernable in the viewfinder that I could focus on.

    But not sure whether this is allowed on Dyxum as in my eyes not strictly photography! - as was 40 seconds of video at 24fps - resulting in approx 1000 images, processed in Pipp, then AS!2 then registax.

    As jupiter is low in the horizon (13deg) at my northerly location there is lots of atmospheric dispersion. This results in the color fringing which I couldn't all get rid of with registax. For where I am, Jupiter's altitude is only meant to get better (higher) by 2023!

    Didn't really know what to expect as first attempt at Jupiter but pretty happy to see some features - though the spot was hiding round the back at the time :)

    Unfortunately I managed to chop off the other 2 (galilean) moons somehow in processing.

    C&C welcome :)

    Thanks CLK. Yes, the 81% shows more detail.

    The factors that make any two moon shots better or worse in comparison are SO many! haha. As it happens both were taken with the same set-up. Camera shake is a big variable - even a tiny waft of air moving has an effect. Manually focusing with my gear is tricky - and often it drifts off while I am shooting. But, by far the biggest factor, is seeing. It changes by the second. And the difference between one frame and the next can be a lot, not just day to day! So, no, I don't really have any thoughts about why last nights has perhaps more detail than the previous - I mostly put differences down to luck with seeing.

    Thanks Mike - I have had good luck with the 80ish moons. My own favourite phases are in the 30-40 % range, but for anything over 50, yes there are lots of great features that come visible around 80% and it is my next best choice. (also the last I usually bother trying to shoot as it grows!) hehe
