Reprocessed “Slightly over quarter Moon”

 

Reprocessed Moon

Bizibilder has been spending his time constructively during the holidays by reading up on various tutorials etc. to try and improve his image processing!  The picture attached is a re-work using some rather fancy software that Bizibilder is still trying to get his head around!  The image is far from good but he is satisfied that he has probably “pulled out” as much as he can from his data (which was a stack of 20 DSLR images of the Moon on a night of not so good seeing).

A slightly over quarter Moon

Moon JPEG

From last night – a Moon made from a stack of 20 pictures.  The focus is better now Bizibilder has had a bit of practice!

Meteor Hunting!

Geminid Meteor

Bizibilder was out hunting Meteors tonight.  The Geminid shower is on view at the moment (just passed its “maximum” in terms of numbers of meteors).  Bizibilder took around 100 photo’s of 20 seconds each hoping to catch one.  He did and , not joking at all, it was the last frame taken!!  The meteor is the bright streak. Taken with just a camera and basic 18mm lens on a tripod.

He has processed the picture in Photoshop to remove light pollution and then drawn onto the picture the “outline” of the constellation Gemini and a part of Orion to help with orientation. He also marked the open cluster M35 also in the constellation Gemini.

Meteors are really only tiny dust particles often associated with comets.  As the Earth goes round its orbit it sometimes passes through this dust.  These particles burn up in the atmosphere and are seen as a “Meteor trail” in the night sky.  These are called the Geminids as they appear to come from an area of the sky in the constellation Gemini.  They are nothing to do with the stars!!

The Pleiades

Pleiades JPEG1

 

This star cluster is easily visible to the naked eye (At this time of year - in the evening sky, SE at around 45° above the horizon).  You won’t see the nebulosity but they are a fine sight.  With the naked eye you should be able to make out seven stars from a dark site (My telescopic field of view only shows the middle five brighter stars of the cluster – Bizibilder will have to make a mosaic to get the whole thing in one image!).  The Pleiades are around 440 Light years away and are “young” - only around 100 million years old – (Our Sun is around 4.5 Billion years old).

The image is 71 x 1 min stacked (So around 1hour 11 mins total exposure time) and processed in Photoshop.  (200mm telescope Canon 1000D ISO 800).  ‘Twas a bit hazy last night and it shows in the slightly fuzzy stars!!

A swift Moon snapshot

Moon 111210

A quick snap of the Moon tonight (around 4.15pm) to check out the ‘scope.  Bizibilder has re-aligned the optics of the scope and needs about half an our of clear sky to get the process “spot-on”.  The Moon looks OK but a star “point” will give a better indication that all is well – then maybe some real imaging can take place after almost a month of cloud!!!

The neighbours think it’s pretty but Bizibilder doesn’t !! BA HUMBUG!!!!

That’s Bizibilder’s observatory in the foreground. MORE HUMBUG!!
