Not Wasdale! This time just yards from home, Christopher persuaded me to get a photo of the Moon setting. It's waxing at present, last night we watched it set a little earlier, soon after the sunset. Not having used the D800 since May, except for a brief attempt with a comet, I struggled with the settings and couldn't find infinity on the 24-120 f4 lens, it focuses a tad past infinity and that is something of a pain. After eight attempts to home in on a half decent exposure the Moon was about to disappear below the horizon I had to accept what I had.  Click here to comment on this image.

I would sell that lens to the European Space Agency...they are struggling to see beyond our galaxy let alone beyond infinity.

Going to have to try this out with my PhotoPils and my 1000mm f11 mirror lens. I have seen these photos before but never had a chance to use the technique. I will do stills not video!

Robert, does the lens get less sharp when you shoot a distant point and use focus past the infinity mark? Lens theory says it shouldnt matter as parallel rays are parallel (e.g. notional infinity source).

Replying from my iPhone so brief (for once!) Yes it's worse when focusing beyond infinity. I think it's because of internal focusing. My 300f/ 2.8 does something similar.

Old thread but the topic is relevant - I have been taking the opportuntiy of clear nights to try and capture some sky shots. Here is one captured and edited on the Samsung S24 - way better than I can get with the Nikon!  Click here to comment on this image.

That's probably because of the large Fstop of the mobile phones. The iPhone is far better at capturing Aurora (f1.2) than my Sony (f4 maximum) ....but useless at getting the moon due to low magnification.  Click here to comment on this image.
