First Sun since the 9th November!!! I took 140 frames over an hour due to lots of thin cloud interfering. Stacked 40 of them to get this image. 120mm Achromat, Canon 1100D, ISO 100, 1/800 sec, Baader solar film:

Bizibilder has a new camera for imaging the Solar system – a good quality high speed camera that is purely “mono” or “grayscale” (i.e. no colour!). To take colour pictures you have to take a red, a blue and a green image using filters and then combine them in something like Photoshop to make a coloured image. Here are the results of an evenings playing around. Scope was my 120mm APO and a filter wheel with Baader RGB filters.
Mosaic using 640x420 ROI and 300/4000 frames. Gain = 0 Exposure = 3ms. Camera speed around 110 frames per second The first two images are through a red filter only – this helps to reduce atmospheric turbulence effects:
As above but this time with a 2.5x Powermate. Exposure up to 10ms and the gain up to 10:
Now my first ever attempt at an RGB colour image:
And finally an "LRGB" image where I added an image taken through an IR blocking filter as "L". Simply added this in Photoshop using "Luminance" - so I'm not too sure if this really is "LRGB"!! (The “L” stands for luminance and is really only a grayscale image added to help with the overall image contrast.)

I took five hours worth on this target but discarded the first hour due to a bit too much light pollution from the Moon!
48 x 5min subs, flats and bias, with a modded Canon 1000D, ED120APO with reducer, EQ6/ST80/PHD guiding, EQMOD.
There is a good clear dust lane across NGC891. Abel 347 is a galaxy cluster of around 30 galaxies - there are at least 20 visible in the picture:
