Gomeisa or Beta Canis Majoris

From last night, lovely blue Gomeisa or Beta Canis Majoris.  36 x 10-minute subs on the Sky 90 array – and yes the averaged data shows a very nice asteroid near the centre of the image.

Doesn’t look like we have a clear sky tonight so the run of clear Moonless nights has come to an end.

A nice imaging run with the Sky 90 array last night.

Had my eye on a big band of rain and cloud running right down the East coast last night – by some miracle it just kept clear of Hampshire.  So yet ANOTHER clear and Moonless night for imaging.

Decided to set the Sky 90 array up on a Carbon star in Gemini, SAO79474 or N Q Geminorum.  As luck would have it, there was also an asteroid 73 Klytia in the same FOV.

Images of the asteroid and Carbon star below.  The small bunches of tiny “stars” in the asteroid image are hot pixels as the asteroid data is “average” combined in order to keep the asteroid.  As this is dithered data there are no hot pixels in the Carbon star image as that has been SDMask combined.

Bubble nebula region from last night

Beautiful clear Moonless sky last night – hard to know where to point the telescopes.  Decided on the Bubble nebula region and the 2 x Canon 200mm prime lenses together with the 2 x Trius M26C OSC CCDs.  “Claws” is not coming out as well as I’d expected with 14 x 30-minute subs and I think this is all down to my rapidly deteriorating skyglow.  I guess a move might be on the cards after all.

Asteroid 8 Flora plus an unknown

Managed to get some imaging in 2 nights ago (Jan 18th 2018) and got 30 x 10-minute subs on 8 Flora, middle of run at 21:32.

You can see to the right and a little bit down from Flora there is another reasonably bright asteroid.  Any ideas what this is?  It does not show up on my version of the Sky 6.

The Belt of Orion

A couple of nights back we had an extremely rare clear, Moonless night.  Gremlins were at work as I have hardly used the kit in almost a year – never mind.  Managed to get 4 x 30-minute subs on the Belt of Orion using the 200mm lenses and the Trius M26C OSC CCDs.

As there were only 4 subs the image is very noisy and the stacker doesn’t get rid of plane trails when 2 of the 4 subs have plane trails on them.  However, what this image does show is that the framing of the Belt is just about perfect with the 200mm lenses and if I ever see another clear, Moonless night, I am going to have to return to this and get a load more subs.

NGC1999 region from 15/12/2017

Got just 9 x 20-minute subs on the NGC1999 region last night using the Sky 90 array.

Forgot just how many geostationaries swarm through this region.

First “proper” image of the season – IC348 in Perseus

First “proper” image of this season. 21 x 30-minute subs on IC348 (in Perseus) on the 3 x Sky 90 array. It clearly needs even more exposure time to both reduce the noise and bring out more of the brown stuff.

98th Earth Science Picture of the Day (EPOD) Today

Managed to get today’s EPOD with an image of Arcturus – the brightest star in the Northern Celestial Hemisphere.

Thank you Jim at EPOD for continuing to publish my work.

3D Printed 5th Order Menger Sponge

Not exactly deep-sky stuff, but it is my other main hobby.  This is a 3D printed 5th order Menger Sponge, 180mm along an edge, printed on an Anet A6 3D printer using Rigid.Ink white PLA filament.  346 hours of printing and 1.5kg of filament went into making this mathematical object.

97th Earth Science Picture of the Day (EPOD) Today

Got today’s EPOD (number 97 for me) with an image of Romanesco Broccoli showing its Fractal structure.

Thank you Jim at EPOD for continuing to publish my work.
