Well Bizibilder must admit that this is not much to look at for the non-astronomer! It is a nebula (a gas cloud, part of one really – called IC1396 - its very big) in the constellation Cephus. Bizibilder was actually trying to image a specific part of the nebula, a dark patch of interstellar dust known as the “Elephant’s trunk”. Part of it is visible top centre! Bizibilder didn’t “miss it” its just that he wasn’t quite sure where it was in relation to the main nebula! The image is not too bright, even though it was a 3h 30min exposure as Bizibilder’s camera is not designed to image red nebulae and actually has a filter that blocks much of the light!

There have been a couple of clear nights recently! On Wednesday Bizibilder started a project to get a good image of the famous “Double Cluster” in the constellation Perseus. Here is the (roughly processed) first hour and 40 mins of exposures (20 “subs” of 5 minutes with the telescope locked onto a guide star via the computer). He has a further 2h 30 mins from Thursday night to process and add to this image – digital imaging is great! You can take pictures on different nights and just “add them together”!

The “seeing” was quite good today but the Sun was low down as Bizibilder can only photograph it after he gets home from work.

From very low down over the observatory wall. The seeing was fair but the altitude low! The big spot AR1302 is apparently "naked eye" size - but I don't advise looking!!
NEVER LOOK DIRECTLY AT THE SUN WITHOUT A PROPER, SAFE FILTER.

A huge new AR has come into view (AR 1302). This should keep the Sun interesting for the next week or two! And I finally had clear skies.... The full disc image is a stack of 100 frames and the avi's were roughly 1800 out of 2400 frames each - much easier than cloud dodging!!

Actually it was Bizibilder in the hurry! There were only a few tiny gaps in the clouds and the pictures needed were taken over about 45mins, two or three at a time! Bizibilder finally managed about 150 frames but quite a few were ”wasters” due to clouds. The final stack is 112 frames to make up the image you see here.

Bizibilder is starting to have trouble getting decent images on the days when he’s at work - The Sun is low over his neighbours houses and seeing is very poor by the time he gets home, especially noticeable in the webcam close-ups. He may have to give up on these soon and just try for the full disc. Anyway the full disc is still interesting with a new spot group (AR 1301) coming into view!

There were reasonably clear skies this morning though the seeing wasn't actually all that good - short periods of fine detail and long periods of "mush"! Anyway I managed a set of pictures - the larger close-up spot picture is a two pane mosaic.

Bizibilder managed to find a gap in the clouds today and took these. The four panel mosaic is a bit messy as he did this last and had trouble with a few wispy clouds. The session was curtailed by a torrential hailstorm!!
