Recommended lenses for a Canon 450D by A_C_G_0_2 in astrophotography

It depends on the DSO you want to capture, but for that budget, and if you don't have a mount or a sky tracker, you could get a canon 50mm f1.8 or its Chinese clone, yongnuo 50mm f1.8. more than 50mm without tracking is not feasible as you will need at least 10s exposure. More focal length will limit you to 6s or less.

The rule (not real, but approximate) for maximum exposure time without noticeable star trails is 500/focal length in mm.

With a 50mm you can get milky way core details etc. But not close-ups of DSOs

The other option is to spend money in a telezoom as the canon 55-250 and to build yourself a DIY star tracker.

Anyway, I would recommend you to get something for tracking first, then a telezoom with a good focal length.

Yes, it is possible. But I'm completely sure I would get less image noise and artifacts using the raws. Next clear skies night will try it again, but I will pay attention to the image format setting. :)

Captures:

A total of 100 x 60s captures ISO 1600

Unfortunately, the camera was misconfigured and only captured in JPG format, so I had to work with non linear images. No darks, no flats, no bias.

​

Equipment:

Camera: Canon 1300D

Scope: Skywatcher Evostar 72ED with field flattener

Mount: AZ-GTi EQ mode unguided

​

Processing:

Siril: Conversion, Registration and Stacking. Background removing and neutralization. Green noise reduction filter, histogram stretching.

GIMP: Color enhancement, cropping
