More Moon

avandonk · #1 03-10-2006, 10:00 AM

Someone asked how my 100ED coped with high brightness objects such as the Moon and any resulting CA. Took some images of the Moon while still twilight. Only adjusted for auto colour balance in PS.
First pic Is full frame, second is a crop and third is a 100% crop. These were all from a single JPG straight out of the 5DH.

Details 5DH 100ED AP FR so 640mm at F6.4, 200ISO and 1/400 sec exposure mirror locked up.

I have not gone over to the bright side, I will leave that to the experts.

I really like the 2nd pic, Bert.

Yep, I was right. We're all going Moon mad

Bert, your Moon pics seem to have a purple/magenta tinge to them. I also noticed this on your SMC + 47 Tuc widefield photos. I've attached your pic of your Moon unedited and also desaturated. Any idea what it might be...? Camera or processing?

Steve the 5D is modded.

I left the colour to show there was no CA. Here is a Moon image taken with a TAL200K at twilight last night.
Single shot 1/125th sec exposure ISO100. Canon 5DH, TAL200k with Hutech focal reducer so 1790mm At F9.
Both images full frame.

WOW! Very nice crisp shot Bert!

And it's a target we can photograph almost all of the time.
