Excellent detective work James – that is a great find! Here is a composite showing Chris’ photo and below it, the approximate field in The Sky.

Hi,

I was out last Monday Night, and a metor went thru my field of view, that was the frist time it happen to me.

I say one other metor later on, but in a different part of the sky.

Thanks,

Tom

Yep Tom,

Its a nice exciting thing to see a meteor go through the field of view in your eyepiece.
I have seen a couple streak through when observing. When in surburbs its cool when one streaks through the eyepiece and observers watching next to you didn't see it as its way too dim for naked eye.

So the final conclusion is that it is in fact a bright star that smeared as the mount slewed and the dimmer stars didn't smear as they weren't bright enough?

Nice find to locate the star. Easy enough to confuse with a meteorite.

This is like CSI Astronomy.

Well done everyone, particularly James for doing something I should have much earlier.

I better make an apology first of all, OK they are stars, weird profile, but stars. I suppose I'm used to oversampled pictures.

The plate solve solves one problem, but opens up another couple for me. Why didn't the other stars trail? Brightness difference?

Why did Chris think he was taking pictures of NGC253, when the camera was pointing at beta-octans? The two objects are widely separated.

Problem (almost) solved, I feel sorry for Chris, but satisfied that we've collectively gotten to the bottom of this.

Cheers
Stuart

Short exposure DSLR stars can appear quite peculiar – I have had similar stellar profiles with my Pentax *ist DS so my previous (short exposure) results help keep that possibility open! Clearly you are being spoiled by your ST-10XME!

Cheers

Another possibility is the autoguider was going nuts and doing really big corrections as it lost the guide star or was set incorrectly. For example when you slew to the other side of a GEM you have to click the reverse X box so the corrections are issued for the other side of the mount otherwise the X errors build up and up and up as the corrections are going the wrong way.

Perhaps why the squiggly tail. The other stars may not have been bright enough to expose well?

Damn you guys are good.

It is CSI Astronomy and it was my gear so my prints are all over it.

Chris, I hope your happy with the end result mate.
Yours will certainly be a post revisited many times and not a bad teaching tool.

It certainly has an an eye opener for me.
