chasing the ISS

[h0ughy]

well i set up tonight - lots of high cloud but i wanted to chase the ISS and try and get a picture of it. i set up where SN told me it would be and checked the star field wit hthe camera short exposure - sorta looked ok. well bugger me i was just above where it came through the brightest - so then it was quick onto the hand paddle and chase the rotter - and shift the dome LOL. well i managed to get it - but only as a sporting shot LOL some game hunter Eh? you can even see where i stopped the mount and hit the camera shutter - then the iss fades offscreen

Some quick action Houghy, you must have been on the ball with that shot, a bit bumpy on the end but well captured.

Just wondering,going by the details of event captured,you had the scope moving along on the ISS,how are the stars not trailing?is this a composite image,Sorry for my question-just not sure how you captured this,certainly looks great-I'd like to try something like this too.if I could find out a few more details-thanks Chris

Nice work Houghy, and a bit of quick shifting as well.

I grabbed a couple of shots over the weekend just tripod mounted wide angle and was happy with what I got.
Will try some more when I'm back on day shift.

Got the latest update for Star Walk for the iPhone and it now has Sat Tracking included so in between jobs here at work I dashed out and told it to find the ISS and bingo there it was exactly where the web site said it would be and Star Walk pointed right at it.

Amazing stuff technology don't you think.

the iss was running away from right to left in the image hence the bumpy look where i started after finding it and stopping slewing - i think it was when i grabbed the remote controller for the camera

It's not your picture, I already told you they were on something up there :lol:

haha yep micael.. your widefield shot of ISS was really trippy that one hhaha :lol:

Still wondering how this image was done,if the photographer had camera taking image while he had controller slewing the scope,Why are the bbackground stars not trailing?Hope someone can explain how this image was taken.

I am wondering was another image taken of the stars and then the trail put over it??

I believe Houghy was slewing the scope to get the ISS into the FOV. Once there he stopped slewing and clicked the shutter.

So basically the scope was either stopped or just at normal tracking and the ISS few out of the FOV during the exposure. IE. During the exposure the scope was not tracking the ISS.

ok thanks for that explanation,I thought may be he was pushing the button slewing on the iss,the way it read-words on screen can be a little hard sometimes

Astronomy can get pretty exciting when chasing these short duration events!:thumbsup: Great fun eh, Dave?

whats not to understand slew to object stop slewing and then take image, the wobble is the mount settling then the ISS moves to the left not the mount

[hotspur]

I understand,just the way your post read-I got the impression that you were slewing on the iss.

I usually, am more organised and have everything set up in advance of these fly over type of events.

Great capture.
