Wow! A rare post from Paul.
Looks like an interesting object - but I reckon it could do with a few more exposures. 1 minute subs? You weren't guiding?
What is the cause of those diffraction-like spikes?

Hi Mark,
Having some problems with my guiding on Saturday, so down to one minute subs, then the sky was getting light so had to call it a day. Will have another go one it starts to rise a little earlier ;-). The difraction spike are caused by the clasps holding the lens in place.
interesting photo,
is the top right hand side supposed to be that devoid of stars?
Yep, it's a dark nebula LDN1470 AKA Bernard 3 and 4.
I've not heard of that one before but it looks very interesting, especially with the associated dark nebula B3 and B4.
That's a good image for 1 minute unfiltered subs, an LP filter and guiding should improve things considerably.
Nice to see you're imaging again Paul.
Nice to see so many unusual subjects being imaged....well done Paul, food for thought
