After being inspired by Steve's image (http://www.iceinspace.com.au/forum/s...ad.php?t=75260) of M87 I decided to try and image the jet emminating from the black hole at the core of M87.
Taking his advice I only did 20x2min subs with the QSI and after stacking was able to plainly see the jet. I've also included a close up of the jet for those who may not see it.
Many thanks Steve for the inspiration as its an object Ive been facinated with and never tried to image.

Great to see what is possible to image these days well done. This object has been on my to do list for many years, I guess short subs are the go not to burn out the core area, also what focal length are you using.
Clear skies Ken.
Thats awesome, congratulations on capturing this cool object. It's good to see others having a go at these exotic targets. You've got plenty of detail in the jet, so I reckon you could upsample the frames maybe 6x before stacking and you'd get a very nice detailed image from this data.
That's what I did when imaging it last year (http://www.iceinspace.com.au/forum/s...ad.php?t=59611). And yes, short subs are an advantage when squeezing detail out of the jet. It is quite bright so doesn't require long exposures at all

Your capture with a wbcam was brilliant but Ive included a closeup of the jet but it really doesn't add too much.
Thanks for the comments.

Thanks for the comments. It was new to me but others have done better. I found that the clouds rolled in and I didn't have time to go very deep with the image. But I can see it and thats all that matters.
Allan, these are things that Mr Simmons normally Amazes mere mortals of, you have inded achieved that celestial plane..... well done
Thanks guys, but Dennis is still a plane too far away.
Only repeating what others have shown is possible. Its interesting in that there appears to be two close very bright knots in the jet which may be these two shown in the hubble shot?!?!?

Yes you've definitely got those two, you can see how the outermost knot is a bit off the jet's axis compared to the larger and brighter 'inner' knot, which corresponds well with the HST image.
I think there may be more detail in your data, it looks pretty good . Was the close-up a crop of the final image or did you try up-sampling each individual frame before stacking? This can often reveal more details.
I took the liberty of trying to bring out some of the subtle details which I think are there. The attached result is rotated 90 degrees and is pretty much identical to the HST image (albeit at a slightly lower resolution...)
It might be worth trying imaging it with a 2x powermate, then I'm sure one would see even more detail. I couldn't with my webcam, but your QSI is much more light sensitive, so it should be possible to magnify it more .
