Canon EOS 650D Modification

[Zowlyfon]

Hi,

I've been looking at modifying my Canon EOS 650D for astrophotography. I started this hobby a few months ago and have a basic setup including a Redcat 51 v1.5 as my telescope, a star adventurer pro and an Optolong L-Enhance filter as well as a ZWO ASI 120mm and a William Optics Uniguide 32mm for guiding.

I've seen that there seem to be 3 types of modification for this camera, a full spectrum modification replacing both internal filters with a piece of Astronomik MC Clear Glass, removal of the rear IR filter and replacement of the rear IR filter with a baader BCF-1 glass.

Can anyone advise me on which would give the better Hydrogen Alpha response while keeping the camera useable for daylight photography too. I do plan to purchase a dedicated astronomy camera in the future, however I believe upgrading to a better mount will likely take precedence due to the advantage of being able to guide on the Dec axis which the star adventurer cannot do.

I've looked at the procedure for the modification and I feel comfortable doing it myself, however I'm not certain on which modification would be best, as I've heard that the baader glass can have optical imperfections, so I'm wondering if just removing the rear filter and using a clip in filter, such as one of the Astronomik Luminance filters, when doing daytime photography would a better option.

Keeping autofocus is not a requirement for me as I do not own any autofocus lenses, around 80% of my use for the camera is Astrophotography.

I've attatched my latest image of the Heart and Soul nebula using my current setup and unmodified camera. It's 50 * 180s @ ISO 1600, stacked in DSS and processed in Photoshop.

Thanks,
