Thanks Paul! Yes I think you imaged it back in 2013 if I'm not mistaken. Without doubt a benchmark image. I actually like the colours you put together as they are more consumable than what I present. The vibrant Ha red is not to everyone's liking.

Hey Steve, Thanks! I think overall I've only imaged around 12 RCW objects in total. I've got a long way to go if I'm going to try image the entire catalog! Some are just too obscure I suspect, or need far more focal length than what I have on hand at present. Pleased you liked it!

I don't have that catalog in astroplanner to find it. Does anyone know how I would access the SL catalog?

Brett
Thanks Brett. TheSkyX also has the Sandqvist & Lindroos catalog if configured to display them. Not to be confused with the Shapley & Lindsay who catalogued clusters in the LMC!

You can always plate solve the image to get the coordinates, Brett. Upload to here: http://nova.astrometry.net/upload

Cheers Rick! Thanks for checking it out. Astrometry.net is a very cool resource, especially for the even more obscure stuff.

Hey Mike, Thanks! Marcus' image is a great rendition. There are few out there. Pleased you liked it.

However, I cannot help it and when looking at the image, instead of a sinister beast, I see a smiling wolf with big fluffy ears...
Thanks Slawomir! A happy fluffy-eared wolf...sounds like a character from a kids cartoon. Perhaps I should photoshop some reflection neb pointy teeth. Thanks for checking it out.

Impressive.
Cheers Peter! Not sure about the top shelf. With fresh eyes, I think I could make some positive changes to the image. Its a never ending quest for improvements yet I'm going to resist on a repro as I've got other data to work on. Pleased you liked it!

I imaged this area last year with the TEC180 and it took quite a bit of processing before I was happy with it. Basically its a very starry area and they can dominant to the general detraction of the image's focus.

The dark nebula areas stand out nicely though so the Wolf is clear.

Greg.
Hey Greg, You make a fair point on the starry field. SL17 is in a star rich area in the MilkyWay so I don't think there is a way of avoid this, nor would I want to incorrectly portray the area. Stars are there to embrace, not butcher. What I found interesting was your comment that you want to see luminance data, but you don't want to see so many stars. Luminance filtered data is only going to amplify the star field so its rather counter intuitive. I'm also not sure where you got the HaRGB from...this is a [Ha+R]GB, yes there is a difference. I think if I were to add a luminance to this image, I would use the red filtered data anyway as the stellar profile is tighter. No need to use a textbook clear filtered data as a luminance for neb work. Anyway, thanks for the good feedback. I may pick up some pointers from you with your RH images given you're going to face the same starry challenges. Just remember to embrace, not butcher.

Thanks Ian! I do have a star reduction tool for PS. I use it sparingly now and then. I find it can mess with the relationship between large and small stars which distorts the presentation. Something I wish to avoid. Thanks for checking it out.
