Re: total lunar eclipse on Sunday / Monday morning

I have one Zuiko OM lens that can be set to "beyond infinity" but nearly all have a stop at infinity which makes it easy to set them to that. The problem with most modern AF lenses is they tend to be varifocal so if you change the zoom position you'll also change the focus distance. That means they cannot have an infinity stop.

Re: total lunar eclipse on Sunday / Monday morning

Total overcast here but I did manage to get up and look!



I like your shot, MJ, and, since you use the same lens that I have, I feel that I know what I would have seen


For focus, I usually set manual focus and view a magnified image on the screen. The 'beyond infinity' is not only a problem with 'fly by wire' lenses. Many mechanical-focus lenses have the stop set a little beyond infinity to allow for thermal expansion and mechanical tolerances. For night-sky photography, I usually set focus on a bright star and rely on the fact that everything up there is effectively at infinity, so it's ok to move around after the initial setting - just keep your hand away from the lens controls.

Ah, 1 second is too long is it for the moon - I took about 20 shots between 1 and 3.5 seconds. As you say, I'll have another go in 10 years. Focus was a little difficult as the moon was darker than I expected. Some wispy cloud did not help.

Here is my attempt, processed in OV3. 40-150mm +1.4TC, but first how it normally looks.


Early in the evening. F6.3, 1/640sec, ISO 250, handheld propped against the window frame.


Blood Red Wolf Moon. F4.0, 1Sec, ISO 600, tripod.
Edit: I've tweaked the OV3 jpeg with a pass through Elements in an attempt to remove a pixels worth of motion blur and reposted the picture. Old one still in my gallery for comparison.

I did have the x2 digital teleconverter on but OOC jpegs did not look as good as re-processing from the RAW (to a smaller pixel count).

Re: total lunar eclipse on Sunday / Monday morning

It's just as well Edwin Hubble wasn't using a modern digital telescope, with AF lens systems, we would still be debating whether the universe is expanding, steady state, or just an array of blurry blobs!

Re: total lunar eclipse on Sunday / Monday morning

Someone posted a brilliant 'blood moon' on Twiter, rather tongue in cheek. It's rather skilful to peel a pomegranate whole!

By then, the 'normal' sensor speed will be ISO 1,000,000 and MFT will be known as 'large format'

Re: total lunar eclipse on Sunday / Monday morning

It was cloudy here south east of Oxford for the eclipse, but I grabbed the rising wolf supermoon at dusk near Stokenchurch in the Chilterns beforehand. The crows were going crazy. E-M1 with MkI 50-200 ZD.

Re: total lunar eclipse on Sunday / Monday morning

Thanks all. Luckily I'd decided to take my old 50-200, which is sharp at f5.6 at 200mm. The rising supermoon took me by surprise a bit as I was looking at the sunset then looked round. Juggling ISO against speed for the crows and aperture for DOF with the trees and moon reasonably sharp was tricky, but the IS kept the trees sharp.

Re: total lunar eclipse on Sunday / Monday morning

For those that missed it for whatever reason here is a time lapse of the Moon eclipse taken with OMD MKII and 300mm +MC 14 on a tracker between 3:10 and 5:40am on the 21 Jan. First time I have tried time lapse of an eclipse.

I set it up about 10pm on a tracker left it running with tape heater on lens went to bed got up about 3:00am and started to remotely control camera indoors using Olympus capture with exposure interval of 20sec. The camera and lens were white with frost but the lens remained clear thanks to the tape heater.

Its interesting to note how vast the exposure range needs to be. The first frame was taken at 1/800 sec ISO200 f10 the darkest frame 1/25sec ISO6400 f5.6 and the last frames the red bit at 1.3sec ISO1600 f5.6

I used Pmode but forgot I had set the max ISO to 6400 should have had it at 1600. Cant remember the last time I used P Mode but it seemed to work here without having to keep changing the exposure settings myself.

Processed in LR and timelapsed in Olympus Viewer 3

A still from this set.

Fantastic work John. As usual.

Re: total lunar eclipse on Sunday / Monday morning

That's a cracking time lapse video John. It all worked out really well and you didn't even have to stay out in the cold.

Thanks Phil. I think remote control of camera using Olympus Capture and USB extender a big plus for astrophotography. Even able to remotely tweet the focus in the warm. I have USB2.0 Extender 50m Transmitter & receiver linked by 30m of CAT6 cable. Total cost £61.
