Title: M13
Post by: MarkS on Jun 11, 2008, 02:09:25
This is a work in progress - I think I can improve the processing of this.

80min total exposure in 4min subs taken on Tuesday night.

Very nice Mark. I was wondering if anyone was going to give one of my photo challenges a go or not.

Fantastic image, as ever, Mark. Always amazing what the camera can do

Mike, I will certainly give M13 a go this month, if weather holds up.

You have introduced a lot of different ideas & spend a lot of time enhancing our enjoyment within the club, that are very welcome. Toast looks good & your imaging sessions always have a good turnout. Wouldn't like you to think your ideas were not appreciated, because they are.

Thanks Fay. When I first joined the club the only person doign any astrophotography was Paul and I thought that was a shame. So with the help of people like Paul and Jeff set out to get as many people as possible involved in astrophotography with Deep Sky Camps and Imaging Sessions and to show that it is easier than people think (sure it is still a hard hobby with a steep learning curve, but it is still within the grasp of amateurs on modest budgets). The huge number of people doing astrophotography in the club now is hopefully thanks, in part, to all those efforts so far.

Saw M13 last night, but I guess that doesn't count.

Are the imaging/?viewing challenges somewhere on the website as I missed the last meeting?

Here's the final version - 120min in 4min subs.

Look very carefully and you can just see some slight fuzziness where IC4617 should be.

Very nice Mark, gives me a benchmark to aim for. My last attempt at M13 looked more like bird droppings on a blackboard than your crisp rendition.
