Just playing with this as 45 mins is nowhere near enough. I just wanted to get an idea of the brightness and size of this one and maybe get more data when it is better placed. It is quite big!

Just a whole lot of stars bunched together in space! officially called NGC752 in the constellation Andromeda. (The cluster appears about the same size as the Moon in the sky). The two bright stars, lower right, are the “double star” called 56 Andromeda.
A bit small - but they are there! A couple of hours on Stephen's Quintet of five colliding Galaxies. They are about 300 million light years away. The annotated one shows NGC numbers. (NGC7320 is a foreground object and is only about 40 million light years away).
SW ED120APO with reducer. Canon 1000D ISO800. Guided EQ6/PHD/ST80. 2h 5min of 5min subs with flats and bias.

By far the best of around a dozen .avi's taken this morning (45Gb worth!!). This one had by far the best quality graph and enabled me to stack 450/4000 frames in Autostakkert2. Sharpening was with Astra Image 3.0 SI using Lucy-Richardson deconvolution. This seems to give much better results than I have ever been able to achieve with wavelets.
Skywatcher Evostar 120mm Achromat. Baader Solar film. QHY IMG132H camera. 1 ms exposures 450/4000 frames stacked. I have included both B&W and false colour images - take your pick! (click to enlarge):

A rather nice, if small, barred spiral in Pegasus. It is about 105 million light years away.
It was very (Very!!) windy last night and around 2 out of three subs were ruined due to the scope being blown about - even though it was in the observatory! This is a stack of 40mins total of 5min subs taken with my usual rig of ED120APO with reducer, Canon 1000D modded, on an EQ6 guided with PHD. Stacked in DSS, flats and bias included.

The BIG Spot !!! I had to break out the winter solar imaging gear to get a shot of this as i have trees that block my southern view from the observatory.
I have an EQ5 that lives on a pier in the garden, covered with an upturned Tesco's 45 litre plastic waste bin, then a patio chair cover (which is waterproof) and finally a green plastic chimera cover (which is only 90% waterproof!). This set up has survived its third year unscathed. The scope is a SW Evostar 120mm Achromat, the camera a Canon 1100D. The mount has dual axis motors.
These are made from a stack of 38/160 frames taken at ISO 100. 1/1250 sec exposure. Baader Solar film at full aparture.
Oh - did I mention _ there is a huge active area visible at the moment?
