Supermoon Texas SD1/300mm

xpatUSA · Nov 15, 2016

Quite a struggle, I'm not used to these kind of shots. :-(

SD1M with 70-300mm f/4-5.6 DG on Giottos 'Silk Road' tripod + ball-head.

To be honest the original capture was quite soft, for all the usual reasons:

Crop of RawDigger 'B' channel up-sampled in FastStone.

Shot at high res. for a change. ;-) Used Monochrome 100% blue out of SPP.

RawTherapee 'Contrast By Detail Levels' followed by RL Deconvolution sharpening, then upsized Lanczos3 from 670px to 1024px wide.

Pounded in even more acutance with Piccure+

Please enjoy my best moon shot ever (for me) - even if it doesn't match up to the Pro's. ;-)

Once in every blue Moon they come out right.

Solid overcast here in Oxford UK.

Very nice Ted, we had rain showers here all night. :-(

PanoMax · Nov 15, 2016

Not too shabby for that kind of subject.

I have a Questar 7, with a Cer-vit mirror, Focal length: 2540mm at prime focus, f/14

I'm trying to get an adapter for a Sigma SD1, but so far they can only provide a Micro-4/3 adapter.

Visually, from the best viewing sites, it will resolve to about .25 arc seconds.

When I took it to Hawaii back in 1980, I looked at a feature on the moon in the Lunar Alps Mountains called the Alpine Valley in which there is a cleft or rille in the middle about 500 meters to 1km in width. I was able to resolve it very nicely... from 400,000 km away.

Alpine Valley, with rille

Nice one Ted,

Just one quick question. Could it be possible you accidentally "flipped" the horizontal on this one? Tycho seems to be on the wrong side...

Best regards,

Lin

Nicely done Ted. Lot's of detail from that old lens and the Merrill sensor.

Beats me, Lin, did you see the raw image I posted?

The camera was certainly the right way up on a tripod.

I'll re-check, still got the X3F somewhere . . .

Here it is straight out of SPP:

Magenta because the dustcover is permanently removed from the SD1 and no filter was put on the lens.

Shot from 30N, 96W at about 4 am today (Nov 15) elevation about 45 degs, azimuth about 240 degrees Mag.

I don't understand at all . . .

. . . apparently, the moon wobbles:

See http://earthsky.org/space/how-much-of-the-moon-can-we-see-from-earth-lunar-libration

and I can't guarantee that the camera was perfectly level :-(

So, which side should Tycho have been this morning?

I guess it depends on where you are too. And maybe from what planet you're shooting from. BUT Tycho is was in the same place in others' shots:

https://www.dpreview.com/forums/post/58653494

Tycho is probable NOT in the same place on my Southern Hemisphere shots taken last night (can't check now as I am at work).

Yep, Tycho is on the right-hand side on the Moon's disc here in Oz.

But not at the same latitude. See Here.

Hi Ted,

The reason I asked is that from Texas, I don't recall ever having seen Tycho appear on the left of the bottom of the moon. It seems to me that something flipped the moon photo horizontally or possibly rotated it. Maybe I'm imagining this but it seems it shouldn't appear that much different that it does from Colorado. Below is a shot I made at about the same time from here in northern Colorado

No big deal - I was just curious..

Lin

Yes, there is a rotational difference between our shots, not a simple flip. Here's yours and mine where I've rotated mine 120 deg counter-clockwise.

Lin's at left, mine at right after rotation CCW.

Meanwhile Mike's montage shots at Fort Bragg do look the same as mine:

https://www.dpreview.com/forums/post/58653494

Quite a mystery, eh?

[edit] the view from Melbourne has Tycho 180 degs off from my original which makes sense to me. Plus Googling "northern hemisphere" images tend to have it at the bottom or to the left. Sorry Lin, but I'm beginning to doubt your otherwise excellent shot [edit]

As it should be seen in Oz:

Interesting... I can't account for the differences, but I have perhaps 20 frames of the moon I've taken with at least five different cameras over the last 16 or so years and all have Tycho on the lower right... I have a friend in Utah who shot the supermoon on the same day about the same time and his also has it on the lower right ....

It would be interesting to undestand the large differences...

Link to some TV station shots sent in by viewers of 2016 supermoon - of all those I can see well enough to make out - Tycho appears on lower right. Strange... perhaps the distance between Texas and Colorado makes the difference...

Looks like we're both "right" + your friend in Utah, so something else is at work here and I retract my doubt about your image.

Gonna read up some more . . if I discover an explanation, I'll post or PM . .

Hi Ted,

It's a head scratch... I've never given it much thought - but in chasing some of my older images I actually found one with Tycho on the bottom left which was made right here in Rocky Mountain National Park. It was hand-held so can't be certain about the absolute camera orientation, but I'm rarely off by more than a degree or so from horizontal in relation to the Earth so if you figure it out let me know and I'll do likewise...

Best regards,

Lin

whisky · Nov 16, 2016

Hi Folks,

Missed the Super Moon due to cloud cover. :-(

Maybe I'm out of orbit but might not the original orientation issue be due to the camera 'Rotate' or 'Auto Rotate' settings ?

I don't think the Moon has gone off on a spin. :-D

Here is one as seen from Scotland, just now checked outside,....... it's still that way. ;-)

As seen from Scotland.

Cheers.

After a bit of reviewing a bunch of images wherein Tycho is "all over the map", angularly speakin', I think the clue lies here:

Loading…

star-www.st-and.ac.uk

from which:

After intense study of that illustration, it became clear as to why photographers in Melbourne had their lenses almost horizontal to see the 'supermoon'. And why that might obtain up there in Alaska, too, but with Tycho the other way up.

Extrapolating from there, there must be a place betwixt the two where the full moon is always dead overhead and a photographer can put Tycho at any angle he likes.

That's as far as I got but I'm thinking that the season comes into it somewhere. We're getting close to the Vernal Equinox - maybe if I shoot again next May, Tycho will have moved a bit?

Or, your longitude makes a difference, bearing in mind Mike's shots from Nebraska being similar to mine?

All the above rambling does not include "libration" where the moon wobbles but not enough to explain the big difference between our images.

Ta for the shot which thickens the plot even more. :-(

As to 'auto-rotate', is the rotation not 90 degs. i.e. portrait/landscape - whereas my image was +120 or so degrees off from Lin's?

Hi Whisky,

Actually, it's not because of auto-rotate or user error of any kind. Most of us posting here have a pretty good grasp of photography and knowledge of how to use our equipment. I've been photographing the moon and planets for well over 60 years with about every imaginable type of camera, lens, telescope, etc., and have the same type images. I have celestial and very high end (Swarovski) telescopes and have spent many, many hours observing. On the other hand, wondering why the lunar features appear to move in relation to the capture is not something I've spent a lot of time pondering. There are literally hundreds of thousands of photographs of the old moon and on these occasions when it gets a bit closer, with the advent of social media and the web, we see more of them from around the world. It was just interesting to see the rather large difference in the relative appearance of this feature between an image made in Texas and in Colorado. I think Ted's diagram explains why and I've learned something today myself!

Best regards,

Lin

Last night I went out at about 9:30 PM and observed the moon to the East with my trusty 7x50mm binoculars. Tycho was well to the right of the 'center-line'.

Out again at about 2 AM when the moon was directly overhead. Tycho was wherever I wanted it by rotating my body.

And out again at 4 AM. With my chest facing to the West, Tycho was back to being well left of center.

So, it would appear that the azimuth and elevation of the moon make quite a difference in addition to anything else . .
