Just a quick M45 11 5 min subs. The moon was bright so this was really to check that my new electronic focuser actually worked – Judging by the star spikes I think I can safely say the focuser works well!
Not my greatest image but was trying out my new DIY focuser and thought the perfect target to test focus was a Globular Cluster. The focus is bang on, however the collimation is out!
Im sure this is my first image every autumn! M27, the Dumbbell Nebula, a lovely planetary nebula high up at the moment in the summer triangle. This was taken with my 200mm SCT reduced down to F6.3/1300mm. The images are all 5 min subs and there are 31 gathered over 3 nights at the end of August.
Taken on 2nd Jan 2017, stack of 32 images….
Galaxy season is here! During the spring the Earth faces away from the centre of the galaxy into deep space and brings into view the galaxies. M106 is located in Canes Venatici and is around 22-25 million light years away. At the heart of the galaxy, as with most is a supermassive black hole and M106 is around the same size as M31, the Andromeda Galaxy and is home to at least 400 billion stars!
Other galaxies in the image are:
NGC4248 @ 22Million Light Years
NGC4217 @ 60 Million Light Years
There are loads of other galaxies but not much data on them! I have included the annotated image as well, have a google and see what you can find out about the others in the image.
This image is 20X 10mi subs, usual setup on 8″ F4 Newt and QHY8 taken in January 2017
Another favourite object of mine, the Leo Triplet of Galaxies, decent amount of data this time, 11X 15min subs. Processed in Pixinsight but really just a bit of a stretch and saturation boost with a wee bit of noise reduction on the background.
This is the Bear paw galaxy, it’s faint and quite a distance away (25 million Light Years) in the constellation of Lynx, I annotated the image with the other galaxies in the frame – I would love to know what the furthest distance is but most of these galaxies have no data on them!
Needs way more data and I think I need my light pollution filter back in as I had some strange gradients in the image but here it is anyway!
I’m not 100% happy with this, the collimation of the scope is out as I need to apply a new silicon pad to the mirror to stop collimation changing when the position of the scope changes, also there is not enough data in this set, its only 9X 20mi subs so I had to do a bit of noise reduction….
Anyway, IC405, the Flaming Star Nebula is in Auriga, the star in question is a runaway star, ejected from somewhere else wandering through space – the light from the star illuminates the dust in blue and the Ultra Violet light excites the Hydrogen gas in this area causing it to glow red. It’s approximately 1500 light years distant from us and spans around 5 light years.
It’s just too good a target not to image each year – the great Orion Nebula, Messier Object No.42….. This year it really was just a test that everything was working, I have cleaned the mirror (scary!), drift aligned(was off by a small amount which was affecting my guiding), collimated the scope and finally cleaned my CCD (scarier that cleaning the mirror!). Thankfully everything went as planned, the previous week the powerpack on my laptop blew, then the PSU for the USB hub managed to come loose) and I got 1.5hrs in 15min subs on Orion before moving to another target but shortly after it clouded over….
Pretty pleased with the image, guiding looks good, collimation as well, so all I need is more clear skies!
