2 years warranty on these used cameras, in good optical condition and technically 100% flawless.
The photos shown are for illustrative purposes only. The cameras are technically 100% flawless and are visually in good condition (grade 3 on a scale of 1 to 5). As these are used items, they are sold in accordance with §25a UStG (differential taxation) - it is not possible to show the VAT separately on the invoice. The camera is missing the cover of the USB port, which has no technical effect.

About astrophotography: Taking pictures of celestial objects such as stars, planets, moons, nebulae and galaxies requires long exposure times and special equipment. Challenges include light pollution, atmospheric interference and the Earth's rotation.
Our modified cameras offer over 4-fold increased H-alpha sensitivity and over 6-fold increased sensitivity in the sulphur II line compared to standard models.
Editing: After taking the photo, extensive image editing often follows. This includes stacking - i.e. placing several images on top of each other to reduce noise and highlight details - as well as the targeted enhancement of colours and contrasts. Astrophotography requires a lot of patience and technical expertise, but rewards you with impressive images that reflect the beauty and size of the universe.
Even with an unmodified camera, H-alpha rays (656.28 nm) can be recorded at the visible edge - however, these require significantly longer exposure times. By removing the blocking filter, we extend the spectrum of the camera up to 700 nm so that the H-alpha rays reach the sensor unhindered at shorter exposure times. This enables a faster image sequence, which is an advantage for subsequent stacking.
The sensor of a Canon DSLR consists of several optical filters, including the phaser layer infrared-absorption glass filter responsible for H-alpha blocking. In our workshop, we remove this filter using cleanroom technology and adjust the sensor's flange focal distance according to Canon specifications so that it continues to provide a sharp image in all areas - even with accurate autofocus to infinity.
Image (1) shows the sensor of a Canon EOS 1000D, which contains the aforementioned filter (4), among other things. After its removal, the sensor (5) remains protected thanks to the uppermost low-pass filter (2). This filter also has an integrated sensor cleaning system - a piezoelectric element that shakes the surface at high frequency to remove dust particles. This is the converted sensor modified for astrophotography; the sensors of other Canon EOS cameras have a similar design.
