About this product

Model: zwo_asi1600mm
Part Number: ASI1600MM

ZWO are well known for their lunar, solar and planetary imaging cameras but this new model, with it’s large (4/3” diagonal) sensor, is aimed at deep-sky imagers.

It is the shift from CCD to CMOS that most interests us.

Imaging with CMOS will probably require a different approach, tests suggest more frames / shorter exposures work better than less frames / longer exposures. This takes advantage of the CMOS sensor's very low read noise and stacking more frames suits the type of data CMOS sensors produce (12 or 14-bit, rather than the 16-bit we are used to).

From a practical point of view the ASI1600’s large sensor means those using 1.25” filters will need to mount them as close to the sensor as possible. Flat frames can be used to even out uneven illumination at the frame edges.

Includes an M42 extender ring that, when removed, shortens the back focus distance to only 6.5mm.

All ZWO cameras include a 2-year warranty.
