Hi Rod,
thanks for your report!
I had the Helix neb on my "to-do" list and then gave it away as I heard it was incredibly feint, so I thought oh what chance have I got from suburbia. But your report has re-ignited my interest to have a go. I'll be sure to only look for it using the OIII filter. Knowing this, has saved me valuable observing time trying to hunt it down. I didn't realise it was so BIG! Half filling up the fov on a 27 Pan, is something to behold!
Oooh I can't wait now..
