Fake Moon shot?

[xclusix]

Hey guys, i was just wondering, this guy i know claims to have taken this image last night (March 14th):



Uploaded with ImageShack.us

But, this image i think shows the current wrong phase for Mexico am i right?

He also claims that it was shot with a 70-200 + 2x converter wide open...is that level of detail possible on a 50D?

Thanks!

Moon phases are the same all over the world on the same night. With a 200mm and 2X on a crop body, he's at 640mm. Not a real lot of magnification for the moon. The moon's image on the sensor plane would be about 6mm diameter, but he could have cropped it a lot. I would guess it's been sharpened quite a bit. Looks entirely doable to me. Nice shot.

He gave me his permission to post it here, this had to be done on tripod and about F/8.0 right? lowest ISO possible...? thanks...

It's spot on for the correct phase, and I can't see anything that would suggest it's not genuine.

Get him to post the image with the exif data intact. That will show camera model, lens, date, exposure settings.


The only problem is that it's upside-down

Very sharp for a zoom + TC on a APS-C body, even allowing for PP.

If in any doubt, just start up Stellarium and plug in your mexican friend's location. Have a look at the moon for the date and time in question. See what he would have seen. Simple

here is one i took a couple of nights ago with a 70-300 no extension tube or anything else on my eos 60d

[hagz]

not quite as sharp but it was my first attempt and it is blown up a little

[martyn_bannister]

Taken tonight using Canon 10D mounted prime focus on 130mm reflector, stacked 17 images and sharpened unmercifully.

[xclusix]

Well i guess ill never know, the 60D+70-300 shot is impressive as well...this guy wont provide RAW image, PP method and the jpeg given has no EXIF...so... ill have to belive him. Thanks you all!

PS. i tried it on my 7D with a 300F4 and i just cant get that much detail without stacking...i dont know how to do that BTW...

[hagz]

if you ask me the 50d is shot is extremely sharp i did a bit of an experiment and sharpened my image in it's max resolution and then cropped it it does look sharper but not that sharp lol.

[martyn_bannister]

I think the "seeing" has a lot to do with how sharp an image results. No doubt in Mexico the seeing is a lot better than the south of UK

No no i did some tests and with a 300 and 1.4x at f8 on tripod ISO 100 and lots of PP my image is not that sharp... I cant just belive him... Any good PP method you know? What i do is no NR raw from DPP then little sharpening, into PS. In PS CS5 i do levels layer select aplly, crop and then USM for overall contrast. Then on a new layer high pass filter and mask over where i want it sharper with hard light blending mode... Is that any good?

I've taken lots with my T1i (15MP) + 70-200 MkII L + TC's, here is one from 3/16 with 2.0 & 1.4 TC for 560mm, cropped to 1947 × 1558, posted 1024 x 819


IMO, the OP picture has too much detail, I've never been able to capture that much detail in a single shot thru my 70-200 MkII L + TC's set-up.
Either he stacked the shots or thru a scope, IMO

However, he is your "friend", possible very still air in high Mexico area gave opportunity to capture that detail?

Here is one that is close to that detail, taken Jan 12, 2011 9:20pm, a single shot, still not as crisp.
First quarter Moon on 12 January 2011 at 6:32 a.m. Eastern Standard Time.
Phase of the Moon on 13 January: waxing gibbous with 62% of the Moon's visible disk illuminated.



vs "the study shot in question
Phase of the Moon on 14 March: waxing gibbous with 67% of the Moon's visible disk illuminated


like others have said, the moon is flipped over, like thru a scope and he forgot to flip it back in PP.....

Well, the answer is, if you can't quite believe the first shot is real, ask for another If your friend can produce on demand, they must be kosha.
