Does anyone know of a list of astrophotography DSOs, specifically nebula, that would tell if they are emission or reflective and how to best photograph them (such as best filters)?

Same kind of question was just asked recently.

And the answer then as it's now is, not likely. It would mean a lot of work.

 

I would recommend just search for Astrobin for different targets and look filter is used.

Hi Carol,

 

Maybe looking at Telescopius and filtering objects according to them being emission or reflection nebula will help you.

 

In general, emission nebula have strong Ha and depending on object strong OIII and SII. The latter two differ quite a lot between objects and especially SII tends to be quite weak. If you have a mono camera then obtaining 3 NB filters (Ha, OIII, SII) will give you many of the options for all the emission nebulae. If it's OSC then there are duo-tripe band filters availble out there.

 

Reflection nebulae are broadband hence no narrowband filters should be used. Depending on your camera, you will need RGB (and L) with mono and uv/ir cut with OSC.

Charlie Bracken has a list in The Deep-Sky Imaging Primer of his 60 top deep-sky targets in the Northern Hemisphere, with brief description of size and type that's plenty to start with. His Astrophotography Sky Atlas has a more comprehensive list with 100 targets, from both hemispheres.
