Bizibilder has added a further two nights images to his Rosette project. The image above contains a total of seven hours of exposures. (And a total of 210 separate images in total – including those mysterious “darks” and “flats” that Astro-imagers have to use!).
A Larger version of the same image is here: Rosette - Large

This is 2h 30 min of data (more being collected tonight,as Bizibilder writes these notes). The upper two are (Messier) M65 and M66 the lower one is NGC3628. All three are spiral galaxies about 35 million light years away. They really are a close group – not just a line of sight effect. The difference in appearance is due to their different orientations in space. NGC3628 being almost “edge on”, you can see a huge dust lane running through its centre.

Three galaxies in the same field of view in the constellation Leo. Bizibilder has just started tonight’s imaging run and intends it to continue for around two and a half hours – we’ll have to wait to see the outcome!

Just to give some idea of apparent size the above two images are of the Rosette and the Moon taken with the same optical set-up. The Rosette is, of course, quite a bit further away than the Moon – about 5000 light years away! and is roughly 130 light years in diameter (it takes light, travelling at 186000 miles per second, 130 years to get from one side of the nebula to the other – so it’s quit a biggie!!)
Taken last night this is the Rosette nebula in the constellation Monoceros. It is a total exposure of 2h 20mins using Bizibilder’s newly modified camera. The modification was to remove the cameras normal filter that blocks the red end of the spectrum (all digital cameras have this filter) as many astronomical objects emit light within these wavelengths. Now Bizibilder can capture the true colours of these so-called “emission nebulae”.

Just playing with the new camera really so here are a few more pictures of the Royal Caroline that I finished building last year:

From the other night (1st March). Mars is not favourably places at the moment so the disc is very small.
And then someone on one of the Astro forums had a look and taught me how to do a rather better process!! SAME image – just enhanced a bit!
