[BAA Comets] 174P Echeclus long exposure tonight

[Richard Miles]

Peter,

Good to see you are keeping a close watch on 174P: a comet that has much in 
common with 29P/S-W1, which had an orbit rather similar to 174P a couple of 
thousand years ago according to the work of Alessandro Odasso. You have 
started amass a nice series of images as the dust and debris from the 
outburst expands into the vacuum of space.

I see that 174P is just approaching its stationary point this weekend moving 
at just 0.016 "/min so a good time to take deep images.
Unfortunately, its path takes it in p.a. 330 deg or so passing between the 
two stars next to the comet as shown in your latest stacked image.

Today I managed to mount my new scope and the weather forecast is clear for 
Sunday evening when 174P arrives at its stationary point. So will see if can 
give it a go on Sunday. Like I say, the coma will be spoilt by the two 
background stars and if the seeing is poor than the result might not be that 
pretty!

Hopefully several folk will give it a go during the coming nights.

Cheers,
Richard Miles
