M16 this summer.

This is the image I shared in tonight’s meeting, M16 the Eagle Nebula and cluster in Ha, with the ‘Pillars of Creation’ in the middle. Nearly 3 hours (34 5-minute exposures).

I also grabbed a luminance layer for the globular cluster M14 to use with my RGB data, and this Luminance only image of M11 to add to my ‘Messier Collection’.

This is classifies as an open cluster despite being quite compact, to me it looks more like a small but raggedy globular!

At last! Noctilucent Clouds

It’s taken me years to see, let alone photograph, noctilucent clouds.

Luna the Lab decided two trips into the garden weren’t enough last night, despite being let out at 11:50 and 1:15. I wasn’t annoyed though as the first two let me test my SQM which gave readings of 19.22 and 19.40 which suggests it’s in the right ball park.

But a couple of hours later she woke me up again, she’s obviously being fed too much.

I took thr meter out and the sky was already starting to lighten and read 18.8sih, but I noticed a few tufts of promising cloud right in the north between the trees.

I got Luna back in, dressed enough not to be arrested and legged it up to the Waterpark.

Thanks to the miracle of image stabilisation, some of my images came out OK co0nsidering they were >1s exposures!

I’m sure these are the ‘real deal’ because the stars were still out and it was just after 3:00am, the clouds were due north across about 45 degrees of the sky.

M13 – Great Cluster in Hercules

I’m particularly pleased with this image. I’ve been wandering around the southern sky picking up ‘missing Messiers’ for my collection, but a few nights ago I though I would try and get some better data for M13.

The initial red subs were a bit poor due to the lack of real darkness, so I took about an hour of subs and chose the best. For green and blue I took about half an hour’s worth of 2 ½ minute subs.

My first process was a bit meh, so I re-did it focusing on bringing out faint detail and being incredibly careful with curves not to bleach the core. Even then on my final curve stretch I had to mask out the core but was rewarded by an extraordinary number of very tiny stars in the outer parts of the cluster. View the image full size and zoom right in, or just check out the inset at the bottom of this post!

My recent images

After the recent floods, which luckily only affected our garage, it took a while before I unpacked all my astro kit as I’d packed up lots of other stuff, just in case.

I finally got back into gear a couple of weeks ago, and we had a run of good evenings. Here are the results. I’ve discovered I need to make the images smaller to upload. Some of these need more data:

Rosette Nebula in Ha

This is the result of last night’s ‘learning session’, thanks to Rob (who has a very nice little observatory!) for hosting.

Stack of the best 12 images, also using flats generated with Rob’s portable Flat-O-Matic which I think is going to be copied quite soon!

Two Images from 29 November in the cold :-)

I’m sure everyone at Rosliston last night will agree it was a really good evening. It was pretty cold, despite the sky being ‘full of flame’ 🙂

I imaged two targets with my 450D and ED 66. I used the L-Enhance filter again which does a great job of controlling stars while letting emission nebulas shine. Unfortunately it does mute reflection nebula, so it isn’t a one-size-fits  all filter.

Here we go – the Flaming Star and Tadpole nebulas, unfortunately the tadpoles are almost invisible:

And the Flame and Horsehead Nebulas.
