Hi Simon,
What a great idea to image the Pleai... Plyadd... Seven Sisters, well some of them anyway with that scope. Countless images, yes me as well, showing them all and instantly recognisable, but this while probably not unique really makes a splendid picture. Extremely well processed, and had you not mentioned the halo I may have not spotted it blended so well in the nebulosity. You too often tend to understate your skills at times Simon.
Cheers, Ray
