Details:
The comet ISON has increased its magnitude and also a new feature is also developed. Comparing with my own image taken approx. 16 hours before this, I saw no second tail in my previous image. Its a great news to all of us!

that not is Comet ISON ... what comet is it? The star trails not are in the same direction as other Ison photo ...

astromazzo, this IS comet ISON, Ive confirmed with a chart, the tail have 2,5º long at least!

Definitely ISON, a simple check with any star chart will confirm. That tail is an impressive wide angle capture.

…or there is a most unfortunately positioned wisp of cloud!

Why the star trails are tilted of different angle?

This is comet ISON. Just check the background stars/galaxies. There were no clouds while this image was taking. Thats the dust tail.

What if two seperate images do show the same tail structure ;) Do you still consider it as some clouds?

Because there are not moving in the same direction...

actually, the guiding wasnt so accurate, hence the stars trailed
Posted by hims1526 2013-11-14 11:03:25
Ok, in fact the Ison movement is the same c.a. of star trails ... but if the guiding is not accurate, then the shfift generate a slight blur effect in the direction of bad correction ... i.e. that you have indicate. That is a plausible explanation. Many thanks! ... and good work!! (What instrument you used in Obs?)
