Which DSLR Modification? Full Spectrum or Single Filter?

[Rickvanman]

Okay, I'm ready to take the plunge and buy a sub-£400 modified camera that will be 100% dedicated to astrophotography through a refractor telescope (so no AF needed).  I've found a place online that offers an EOS 1300D with either the filter removed and sensor repositioned, or with the full spectrum (both filters removed) mod.  I just can't seem to find information that will allow me to settle on a solid answer as to which one would be best for me.  Are there significant advantages/disadvantages to avoiding the full spectrum version? Which would give me the more detailed images? and would additional equipment like filters be required on either?  will I still get the richer nebulae reds on the full mod version? or will the colours be weird, maybe like a negative? 

I live in a fairly light polluted area and I'm just interested in photographing mainly DSO's as easily as I can, without taxing my brain too much :o) 

Appreciate any pointers - Thanks

You only really need the two filter removed if you you do spectroscopy.

The single filter mod will give you the enhanced red response you're looking for when imaging Ha objects.

There is some information on Juan's site Cheap Astrophotography here: http://cheapastrophotography.vpweb.co.uk

I had a Canon 1100D modified (IR filter removed) & I can't recommend his service enough. I haven't been able to use the camera in real anger yet,  just the odd play, but it looks very promising.

Single filter mod worked great for me.

Thanks for the info. I've taken the plunge and purchased through Juan's site - went for the Canon 1300D with just the single filter removed.   Have also opted for one of those £20 Skywatcher Light Pollution Filters. Hoping the combo might provide some pleasing results..
