A reprocessed Image of M35

Picture saved with settings applied.

The same M35 data as below but this time reprocessed to bring out some of the colours in the stars!  The other version was a bit “monochrome”!!

Nearly forgot… Bizibilder’s picture of Jupiter and its Moons (see post below) received a mention in the “picture of the week” section on the “Stargazers Lounge” forum – Bizibilder is quite chuffed!!

Jupiter’s Moons

JupMoons 1

Bizibilder took a couple of shots of Jupiter last night to show the four Galilean Moons.  The picture is a composite, one of Jupiter (the moons being under-exposed and invisible) and a second of the moons (Jupiter’s disc in this one being very over-exposed).  Photoshop to the rescue and one image pasted over the other!  The Moons are (from left to right) Ganymede, Io, Europa and Callisto.

Star clusters!!

M35Last night was cold so Bizibilder set the scope and camera on “auto” and went in to the warm.  This is the result – a picture showing the star cluster M35 in the middle – quite a loose cluster that is about the same apparent size in the sky as the full Moon. Along with the smaller, tighter, cluster NGC 2518 in the bottom right of the image.  Both these are in the constellation Gemini – The Twins.

(By the way, M35 means the 35th object in Charles Messier’s catalogue of 105 objects and NGC stands for the more modern “New General Catalogue” (of several thousand fuzzy clustery things in the sky!!).  Techie:  200mm reflector at f/5. Canon 1000D ISO800.  11 x 2 min exposures with 40 darks and 24 flats stacked in Deep Sky Stacker and tweaked in Photoshop.  Bizibilder has attempted a bit of colour enhancement in the stars.)

A wee (Giant) planet…

Jupiter 1  Jupiter 2

As he writes this Bizibilder’s telescope is patiently taking photographs of a star cluster called M35 – all fully automatic at last!! (Especially as its –2 and a biting East wind outside!).

Anyhow, a couple of pictures of the planet Jupiter taken about two hours ago.  Not the greatest of images but Bizibilder is pleased that he has achieved these as a couple of “starters”.  South is at the bottom of the images.  The South Equatorial Belt (the lower of the two main dark bands) has been “missing” for a few months but has now more or less returned to its former glory and is nearly “equal” to the North Equatorial Belt in intensity. (Techies: 200mm Newtonian reflector, 2x Barlow = f/10. Each image 600 frames with a webcam stacked in “Registax” and a little tinkering in Photoshop.)

A couple more BIG Moons

Whole Moon

Terminator

Above are links to a couple more pictures of the Moon taken last Tuesday evening.  They are both mosaics made up from several smaller frames.

Its a B I G G I E ! ! !

You may want to take a look here??

Big Moon

This is a composite of all the images Bizibilder took the other night – He has finally managed to join the dots!!!

How (not) to stitch up the Moon!

Moon StitchThis picture is composed of six small “frames” stitched together.  Bizibilder got things a bit wrong and cannot therefore produce an image of the whole Moon – there were a few gaps and bits missing!!  So he had to settle for this “partial” Moon

Good old Coppernickers! (Copernicus)

Copernicus

Bizibilder has been hard at work trying to extract the last detail out of one of his recent Lunar images.  By following a complicated and convoluted tutorial he has come up with this picture of the crater Copernicus. Copernicus is 56 miles across (95Km) and the smallest craters clearly discernable on the image are somewhere around a mile in diameter.

Bizibilder’s been Mooning again!

Clavius Area Bizibilder finally has a webcam that has been modified for astronomy (nothing special! just pull the lens off and screw in an adaptor so that the webcam can replace the telescope eyepiece!).
So – out last night to take some pictures of the Moon and here they are:
Clavius and Barlow Both are taken as a “movie” of 900 frames. Computer software then aligns and stacks all 900 frames (and eliminates any really poor ones) to make a composite image – as you can see FAR better than the few frames that Bizibilder had been using with the DLSR camera!  This “close-up” was taken with an extra lens in front of the camera and is 2x magnified.
Jupiter Barlow crop Jupiter! Also with the webcam and lens setup.  Really awful atmosphere and by the time Bizibilder took the picture Jupiter was low over the neighbours houses – hence the poor image quality.  But you can see the belts and the fact that Jupiter is a slightly “flattened” sphere – it spins so quickly that it suffers from “giant belly bulge” around its equator!! (A little like Bizibilder himself!)
