Last night moon shot

7 posts in this topic

I decided to go outside after my kids went to bed. Wanted to try this kind of set up. Using 400mm f/2.8L IS USM, with 2x extender, and 1.4 extender. In AV mode in 1/250 Sec., aperture f7.1 with a 30 percent crop.

Impressive! Isn't that 400 a little heavy to hang around your neck? grin

Thanks guys! smile

It's not so bad after 10 minutes, but man, it gets HEAVY after a little while! It's a good thing I had it on the tripod. whistle

archerystud - Mike, I'm not as strong I used to be! But you can carry it around for me then. I'll hire you as a mule carry that heavy glass!

Interesting, Marc. A little sharper than I thought possible with the stacked TCs. How much sharpening did you do in PP and what were your sharpening settings? Also, was this shot RAW, or was it shot jpeg with some in-camera sharpening?

That 400 is mighty sharp on its own. Of all the Canon telephoto primes I've used so far, the 400 f2.8L Mk2 (non IS) produced the sharpest images for me (though not by much).

Nice to see yours is able to deliver acceptable sharpness even with the stacking, and your tripod and technique must be good as well. When you're up around 1200mm before even taking the camera's crop factor into consideration, any little wiggle will soften the image.

Excellent work!

Thanks. I learned great deal doing this, played around the settings on the camera till I got the sharpest I could see on the LCD screen of the camera.

You should know that I used the manual focus. Wanted to really fine tune the focus. I also used the live viewing of the 40d lcd screen to see. It was a bit tricky to keep your hand steady as I tried to focus. I shot these in RAW.

I didn't do any sharpening in photoshop, but I did use the noise reduction.

Let me think here...On my 40D camera has got a 1.6 crop, so 1.6 crop x the 400mm = 640mm x the 2x extender = 1280mm x the 1.4 extender comes the total of 1792mm. Yikes. Never really thought much about it till now.

I really wonder if I could borrow a friend of mine's 2 extender and try to stack on with what I have? eek That would make it..3584mm! But I'm sure that would degrade the quality of the picture?

    • arby's fries frozen?  at supermarket?  have to look for them...
    • Oh, just like the Rompers you are wearing around town then.
    • Made some frozen Arby's fries tonight and wow they were great. I would be sold just on the fries alone in this thing.   11mins cooked frozen, better and quicker than the drive thru lol
    • Actually the guy at ace was pretty close. These little guys are for framing steel studs before sheetrocking,  but yes they also could be for sheet metal work even though they are black . But your right hawg sharp and go in fast. 
    • What  a sweet find !!   Even better that you had a camera handy !!
    • Great trade and as of last year I know I wasn't ready to part with Lavine and his potential but that all changed when he went down with the injury.  I hope Lavine becomes a stud for Chicago in a few years but our time to win is now with this addition!!  Great move giving up hope for a top 15 player in the league that plays D is brilliant with the young studs we still have on roster.  Now all we need to do is add another player or 2 in free agency to strengthen our bench and we will be looking good.  Excited for the free agency to start!!! Playoffs here we come!!!!!! GO WOLVES!!!!!!!!!!!
    • http://minnesota.cbslocal.com/2017/06/22/mall-of-america-slips/   Classic case of doctors juicing up a medical claim with a series of failed therapies, creating a life long patient and a corporation with deep pockets to bill for those services.  Think not?  Dont be so naive.  Nobody wanted to fix her, they just wanted to keep billing, sad deal that happens all too often.          
    • That Drouin contract at 5.5 is kind of bad for us right now. Nino is far more proven than him and Granlund has had the beast season out of the 3 of them. Hard to see anything under 5 for each of them. 
    • Looks like the Wild moved Schroeder for....another Schroeder.  Maybe the new guy will be more consistent.   I see Evander Kane is on the trade market.  On the expensive side, but if the Wild decide to move Scandella instead of Dumba, that would free up more money.  A guy capable of scoring 30+ goals with some size would be sweet.     I am thinking Granlund and Nino each sign for in between 4-5$ mil each.  Hopefully less and hopefully Pominville will restructure a little.  Doesn't leave a ton of cap space for free agents or other guys.     Lots of moving parts in Chicago.  They seem to be moving a lot of parts around to try to work with their cap situation.
