Astrophotography / Re: NGC7203 Iris Nebula in Cepheus, 2019-05-04,05 Manche, France
« Last post by The Thing on Jun 14, 2019, 22:02:23 »Very interesting Matk. I don't use anything but a Baader Neodynium filter however I get a doughnut shape on flats. Never used to so I think its reflections in the scope, I have repainted the OTA and every screw and nut and just need a dark clear night to collimate and test it out properly.

That is very nicely processed and produced a result you should be proud of.

Chat / Re: Great Rainbow this evening.
« Last post by Carole on Jun 13, 2019, 16:11:06 »Thanks for that Mark, I found the second link easier to understand.
I did know that each person is seeing their own Rainbow, I think I learnt that possibly at school but I never learnt about Alexander's dark band. I knew there must be a scientific explanation for it as it always seems to happen.
