I think its time for a new scope!


A man of your woodwork skills should easily be able to build one, surely?


I'm not sure wooden mirrors work that well ;)

:D

Mike,
I was going to build a 12'' Dob.
But then we got to working on the clubs 12''.
We are gonna restore it fully and when she's done it'll
be an awesome piece of kit.

A good image Kieran, I had similar problems with the image processing.
I had a good look at this comet through the 12" tonight and decided to put the canon on the back of the scope and try get a pic or 2.

This is 300k, so sorry in advance to our dial up friends.

This was a 20 x 2 min exposure run (iso 800) with 3 discarded so 17 were stacked in registax, the images were full resolution for the camera and brought down to a more manageable size after processing was done.
You can see a gap in the star trails, that is where the discarded pics were. This is a full FOV image with the canon+12", I even used a dark frame. The central point was clearly seen as was the coma in this pic.
There is the makings of a tail to the lower right as the outline becomes diffuse compared to the upper left.
This was a very tough image to process without getting the onion effect gradients appearing in the coma, I don't know if you see that effect with your monitor, the comet is fairly smooth on my monitor, although the jpeg compression does put very faint colour ovals in there. The bmp version of the image was silky smooth.
:(
All the same, I've never seen a comet quite like this one.!

Ah now Frank, don't be thinking of such "small" numbers. ;)

Dave,
definitely a hint of a tail in your image directly connected to the nucleus.
