Well, after working for a while on my last project, I have managed to access the firmware of the Canon 1100D (Rebel T3) to change the firmware so that the camera can compensate automatically for the shift in colour created by the BCF corrector filter. Now when the DSLR is used in any of the automatic camera modes, as well as Auto WB and Auto ISO, the camera will produce colour corrected, realistic, daylight terrestrial pictures without any further post processing or any need for a custom white balance.
As far as I know, nobody is offering this modification so it will go on sale worldwide in the next few days and we'll see the reception of this possibility.
Because a second hand canon 1100D is similar in price to a new camera, I will offer this mode with new cameras; with and without the 18-55mm EF-S lens. They will go on sale for £399 and £440 respectively and the price accounts for the £53 Baader corrector filter.
I'm showing two pictures underneath. One of them was taken by a stock unmodified Canon EOS 1100D. The other picture was taken by a Baader modified astrocamera with this firmware enhancement. Can you tell the difference?

I can't wait for some clear skies. Thanks to UK Astronomy Buy & Sell, I've managed to find a second hand Orion Starshooter autoguider at a very good price (thanks Peter). The next clear night I'll try it out while testing the last couple of cameras I have modified.
So far, I have been guiding with a Philips 880 SPC flashed camera in my Stellarvue F50 -a finder that takes eyepieces. Finding and centering a bright enough guide star has been a struggle and I can't wait to try a proper autoguider which should give me plenty of stars to choose from. That will save me a lot of time and frustration.
So far, I've been using a 2X barlow to extend the focal length of my finder to 400mm. This has obviously significantly reduced the field of view and and made very difficult to centre the guiding star. I've been advised to use the OSA without the barlow as the 200mm FL of my finder should apparently be enough for autoguiding.
One of the things that caught me by surprise is the weight of the OSA. The webcam is much lighter and has given me nice planetary images but I must simplify the guiding process, particularly in this weather with so little astroimaging time!
