Arrived home very early this morning from 2 weeks in the Dordogne spent mainly relaxing round the pool. It was a nice sunny day in Kent so we spent the day recuperating from the journey by sitting round the pool!
Imaging wasn't so good this year in Riberac - there were only 3 nights I was able to take advantage of. My hand has now recovered sufficiently from surgery to allow me to begin imaging again. Anyway, here's a very quick process of the image I took on Tues 30th August.
37 x 5min at ISO 800 using H-alpha modified Canon EOS 350D on Tak Epsilon 180ED at F2.8 and using CLS filter. This was only done a a quick experiment but I think it shows this to be a promising area of sky.
Here is a small, cropped version:

A larger version (2/3 scaled) is here:

Unfortunately the image is let down by issues arising from collimation or wonky T-ring (the latter came loose and I haven't done a proper fix since). Distortion is obvious in the top right and bottom left

That's a really lovely image Mark and the star colours are great as usual. At this scale and even in the 2/3rds size there are a lot of people that would be well happy with that level of distortion.
Robert
That's a great image, Mark. I'd be quite happy to put up with this amount of distortion!
A really lovely image Mark, beautiful stars colours. The distortion is minor.
Carole
Very nice image Mark with fantastic detail.
Are the cyan stars a product of the CLS filter ?
By the way, nice to see you have recovered sufficiently to get out imaging again.

Hubble bubble, very nice Mark. Flobalob - makes my scope look like an optical flowerpot :!
As always a fantastic image,
Give's us all something to aim for

That is a 'FLUBBERLY' Bubble... absolutely superb - FOV & colours are fantastic - that's a great image Mark - Well done - John.

Yes - the CLS filter does have this effect but it is not objectionable.

I agree, it's just a shame it introduces a false colour.
Run out of original positive things to say about your images, Mark! As ever the quality that we now expect every time!!

That's a ripper mate! I wonder if I can see it down at 35 south?
