Today’s Effort – The Sun seems to be getting a little more active again.

Today’s Sun – quite a few spot groups starting to appear.

Mars from the evening of 24 March

A nice little sequence under reasonably good seeing conditions.  The white “blob” at the top is the North Polar Ice Cap.

The only good thing about British Summer Time is that Bizibilder can take some Solar images when he gets home from work with the Sun at a reasonable altitude.

Rosette Completed!

Picture saved with settings embedded.

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

Good old Sol!

The above are today’s Sun images.  The additional one was taken through a green filter – the idea being that this should enhance the surface detail.  Bizibilder is not so sure!

And here is the first night’s data of the Leo Triplet….

Picture saved with settings embedded.

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.

Tonight’s target is the “Leo triplet”

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!

An idea of size


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!!)

The “Rosette” Nebula

Picture saved with settings embedded.

Or bigger:

Large Rosette

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”.

Managed to get the Sun today:

The Sun today–from the observatory!

The Sun is finally high enough in the sky for Bizibilder to be able to see it over the top of the observatory wall when he gets home from work.  It must be official Bizibilder Spring!

Three Planets in one night:

11 Mar 2012 Three Planets

All three taken around 19.00 GMT yesterday evening.  The optics used for each picture are identical so the planets relative sizes are true.

Finally a clear sky!!

Today’s Sun, including a huge active area – 1429/1430.

Mars! A first picture for Bizibilder

From the other night (1st March).  Mars is not favourably places at the moment so the disc is very small.

1 March 2012 Mars

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!

Mars reprocess

Tonight’s Moon

With Bizibilder’s new camera – the “old” one is going to be modified especially for better astrophotography and will not be used for “ordinary” photo’s any more.  Just a test shot but it’s not too bad!

Messier 51 from 24th Feb

A bit late posting this one as Bizibilder has been playing with some new tutorials to help(?) his image processing.  This is a three hour exposure but is still noisy and needs quite a bit more!

Picture saved with settings embedded.

The Moon 1st March 2012

A reasonable picture for once – the seeing was quite good!
