Sharpening challenge

right-click the DNG link and select 'save target' (or similar). Then save the DNG to your machine and open it from within Photoshop or whatever. i.e. File - Open.
or right-click the file on your machine and select 'open with'.

Ahh, yes - cheers! I'll have a play.



I had a go with just taking a ATL+PRT SCR screen dump from here

Seems to have shaprened up quite well, crop is maybe a bit severe though

he he

I might have over sharpened a touch, but I think it is clearly defined.

need to click-thru to the original to reveal the true sharpness. wow!
We need a 'Like' button. has this been asked before? Mods? anyone listening?

I got rumbled. Thanks for taking it in the right spirit. Moon photos are a personal and addictive thing. It's really just a technical exercise and the challenge is to get the best out of you own kit rather than compare anybodys pics to anybody elses. Moon shots really do benefit from a lot of sharpening and or tonal contrast. I have a telescope which collects a lot of light so I try to stick to ISO100 to give me maximum pp flexibility.

The second photo is really just past the point where the Moon looks at its best - which I find is from 3/4 days into the cycle to day or so past first quarter (and the mirrored equivalent for the last quarter to waning crescent). That is probably why areas look less sharp than others. Edge to edge sharpness is also an issue for a single shot - I can just about get enough not to bother with stitched shots. The amount of water in the atmosphere makes a big difference too. A really cold night will hold little and gives the clearest views. I normally find the best time to shoot is at the end pf the blue hour.

I would definitely go for a telescope over a mirror lens. You don't have to spend very much and you get something useful to play with.

I have a reflector telescope. I can't achieve prime focus so I have an eyepiece with a thread which takes a coupling ring to attach to a lens. I use the K35mm f3.5, but I've pretty much reached the limit of quality. So I'll order a different adaptor to try different lenses. I wonder what the Q's crop factor would produce too, could be good.

I missed the total lunar eclipse last year - too cloudy. I'm still gutted about it as I could have got some great shots.

I don't do other astro as my telescope can't track for long exposures.

Those are very good results from the 55-300. I have found the most enjoyable thing is trial and error rather than to follow someone else's methods. And I find the exercise has benefits for other subjects too.

LMAO - the winner so far for me.


Funny how the Dr's April fool actually makes you try harder, but alas...

Definitely something I want to get into, if the price is right, some of those Astro Amateur Prize winning shots from last year really do amaze, that one where the guy caught the Space Station passing in front of the Sun is lodged in my mind forever.

No improvement, truly hit the limits of 55-300. Passed sometime anyway, cheers!



Might go back and look at the 'close moon' one I took last year now too.

I thought I'd have a go anyway and yes, it's your image
