Partial Mod (LPF-1 mod)

DEFLT-LPF-1

The partial modification allows for extended sensitivity in the red spectrum at a moderate cost. This modification is generally of high quality on most recent camera models (provided that the partial removal of the filter system still allows for focusing with a camera lens. If your camera model is not listed as eligible for this modification, it may be due to this or other reasons. If you don't see your camera listed, feel free to contact me).

We offer partial mod (LPF-1 for Low pass filter) for all Canon and other cameras with a dual-filter system, starting from the Canon 400d.

The first filter in the light path is part of the piezo anti-dust system and functions as an anti-infrared filter. The second filter is bluish and largely blocks the transmission of Ha photons.

During the modification, the LPF-2 is removed and replaced with nothing. All anti-infrared filtering relies on filter No. 1, which may result in some chromatic aberration on bright stars. If you want to avoid this phenomenon and achieve maximum quality, you need to enhance the filtering of filter No. 1 by adding the 4'Astro filter that drastically cuts near-infrared in place of the LPF-2.

Nevertheless, with relatively well-corrected optics, this modification is sufficient to access the Ha line under good conditions in an economical solution.

Since the optical path is modified, we recalibrate the sensor to maintain AF and infinity focus with all lenses.

To take advantage of this offer, send us your protected and packaged Canon EOS camera, along with a copy of its invoice, to the following address:

Richard Galli - EOS For Astro
69 rue des Vignerons
68230 TURCKHEIM

We modify your camera, remove the original LPF-2 filter, reassemble, clean, inspect, and test it (photographic dust check, work under laminar flow hood) before re-shipping it in careful packaging.

Place your order online, then print the order form received by email and send us your camera along with the order form and payment. You can also order this modification via PayPal; in that case, send us your camera along with the PayPal confirmation email, and we will return your modified, tested, and fully functional camera.

All our camera modding are guaranteed
