Jupiter "Bird Strike" July 27th 2009

[Quark (Trevor)]

Hi All,

Imaged Jupiter last night July 27th. Seeing was not good 4 to 5 / 10 with frequent periods of unsteadiness. Looking forward to the High pressure system that should arrive by the end of the week.

This is an R channel image captured for 2 min's at 12:43 UTC CMII 217 degrees. Source of CMII data was Jupiter 2.

This is a 3,600 frame capture processed in virtual dub, ninox, Registax V5, Astra Image Pro 3 and Adobe Photo Shop CS4.

Due to the relatively poor seeing I was only able to stack 829 frames of the 3,600 available.

The image was captured with a 16" F4.5 Newt on a GEM with a Annsen Technologies dual axis drive & drive corrector, a JMI Moto Focus, Orion filter wheel & Astronomik Type II RGB filters, a 3x TV Barlow working at 5.3X with a DMK 21AU04 CCD. Scope was working at F23.6.

Clearly the Bird Strikes morphology is changing and the scar is becoming more elongated. However, even in poor seeing the scar continues to have quite high contrast to the surrounding region and even in the Blue channel it clearly remains visible.

I also have some RGB's and more R channel avi's to process, perhaps I will have more to post by this evening. This R channel image represents about 4 hrs of processing.

Thanks for looking
Regards
Trevor

Thanks Trevor, nice big image scale.

I gave up last night - I could "barely" see the scar visually through the eyepiece while waiting for seeing to improve, but it never did improve.

Hi Trevor

Nice image, it really shows quite well how the Wesley Impactor Scar has lengthened and generally spread out. Like Mike, I think we were hammered by the jet stream, so I didn’t even bother setting up.

Cheers

Nice work Trevor despite the conditions! Certainly has spread out, as Dennis said. All cloud here, but hopefully a chance will arrive soon.

Cheers -

Thanks Mike, on the ABC radio this morning a guy from the Weather Bureau predicted that this big high pressure system coming across from the west will be centred over Broken Hill on Saturday. Looking at the synoptic chart predictions through to the weekend, it should reach you and Anthony also by the weekend.

Looking forward to using this image scale with some decent seeing.

Thanks Dennis, I think it is most interesting that, even though it is spreading out, it still remains clearly visible.

Thanks Rob, it is important to monitor this feature if at all possible, to plot the changes occurring within it. I think by the weekend we all may have better conditions.

Nicely done Trevor, thanks! I'm still under rain and cloud here.

cheers, Bird
