Hello all,

 

very often beginners ask what can be achieved with unmodded DSLRs, if it is worth modding, which target works, etc.

Here is an example of the bubble nebula, 61x 2min with an unmodded T3i at ISO 800, 100 bias, 72 darks, 30 flats, Bortle 4 (estimated by clearoutside, not measured)

It was just a side route I took while processing the data to a OSC-Ha blend (posted before in BII). Hope it helps someone making decisions.

 

clear skies!

Fantastic! I’m kind of enjoying the simplicity of the un-modded image...

I know in my brain, there is more data in the second one, but.... I like the first one better from an artistic point of view.

Wow that's really cool! I tried my hand at doing the heart nebula with an unmodded camera and the results were pretty good. I was hesitant to try this one but now I probably will. What focal length did you take this at?
