Best result I've managed to date - there's still a couple of seagulls lurking in one corner but overall it appears to be much, much better than before.

Also added another 1mm spacer to the image train in front of the camera which has really helped the coma in the corners.

90 mins Ha.
Wanted to have a crack at M16 but only got a single sub in before it hid behind the neighbours' tree!

Not perfect, but I'm almost there now!

As an aside, if someone out there offers a collimating service, TAKE MY MONEY!!!

Anthony (former Bintel manager on Camberwell) runs a telescope repair and servicing operation from his home. He told me he can do RC collimation. His contact is 0411 046802 or anthony@battes.com.au
Cannot attest to the quality of his work, but others I now who had their scopes done at Bintel when he was there told me they were fine.
