Fantastic. How did you modify your camera?

Very nice result!  Can you tell us a bit about the sky conditions? We’re you somewhere dark? What about the processing involved?  Again, well done.

Re: The Flame and Horsehead!

Thank you,

It is standard Ha astromodification - replacement of glass in front of sensor, which allows to pass through wider spectrum of light, specifically toward IR. (More red).

I live in bortle4 area, no filter were used for this. Images were stacked and edited in Pixinsight, with final touches done in Lightroom and Photoshop.

Very nice. ISO 200, that is surprising. I am understanding more why questions regarding astro mods are popping up .

I have about the same integration time, but at ISO 1600, non modified, much noisier as would be expected.

Cheers

Seems you are a wise one.

Ha mod seems to be the best option for general astrophotography as there is no need for an additional UV and IR cut filter.

Would go full spectrum only if shooting ordinary IR landscapes.

Astronomically there are no IR objects to record anyway (that light is blocked by the atmosphere anyway). But Ha - that's it!

With cem70 i have the luxury of long exposures at low iso and maximum dynamic range.

That is important with such motive that has a very bright star and faint nebula.

The D7200 is very nearly ISO invariant, meaning that shooting at ISO 200 and boosting exposure in software by three stops has no real penalty in terms of noise performance vs. shooting at ISO 1600. This can help on subjects like the Horsehead with bright stars since it allows lots of dynamic range in each sub—less tendency to clip highlights at the lower ISO. Differences in noise are probably down to Ha sensitivity, sky quality, and processing rather than ISO used.

Re: The Flame and Horsehead!

So the optics were Sigma 150-600mm?  Pretty impressive for a photo lens.
