Here's M16 & M42. 1h on each with a Baader UHC-S filter from the same wednesday night I shot the rest of the pics. M16 was a little close to the moon and M42 a little low on the horizon still but it came out ok I reckon. That was taken with the barlowed newt. Thanks for looking.
2 more great shots Marc.. That setup is really showing some promise! How did you find the resulting colour balance after using the UHC-S? What are the benefits of using a UHC filter at a dark site? improved contrast between the nebulosity and the sky background? Does this at all interfere with the dimmer nebulosity or is that simply a matter of more exposure?
Does it in any way tighten stars up a bit like an NB filter would?
Sorry for the myriad of questions.. Just trying to figure it all out !

Thanks Alex. I just used it that night because the transparency is so good up there that I usually get internal reflections so the filter although designed to enhance nebulosity tend to tame the stars a bit. But I don't think you really need it under darks skies. You do need slightly longer exposure but no by much. It also pushes your red channel right up so you need to take that into account when processing and color balancing.

Thanks Martin. Yes the barlow gives me a 1arcsec/pixel image scale. I have more pixels to play with at processing time and it makes it a bit easier to bring out the data.
Another couple of nice images Marc. I can't help thinking you need to run longer exposures while using the Barlow.
Longer will smooth things out quite a bit and add more depth to the images.

Thanks Doug. What do you expect from an astro-photographer deprived of clears skies for 5 months or so and given ONE clear night? It's like giving a gatling gun to a legionnaire. Shoot'em all

I have to agree with you on this one. Much the same here, New scope and the only thing I can look at is clouds. Even the terestrial things on the surrounding hills are all white with snow or socked in with cloud.
One day, someday, maybe.
That was taken with the barlowed newt. Thanks for looking.
