Howard,
I have to thank you for your Crescent post. Clicking through your previous
images got me to thinking. What did my version look like? So I searched
and searched and found that I have over 100 subs from 2014 that I never
processed!!!!
(Kinda embarrassing)
So I'll post when finished.

Subject: [DarkSkyNewMexico] Crescent Nebula (NGC6888)

Hi all,

I've been pretty inactive over the last few months.
The prevalence of cloudiness during the preceding 8 or so months didn't
help.   Death of my wife in Nov 2017 also was difficult and more than a
little demotivating.  I've been playing banjo at lots of jam sessions and
have taken up learning the fiddle.
Keeping very busy was most helpful.  Now that the weather and my outlook has
improved a little, I plan to devote a little more time to astrophotography.

I continue to be amazed by the images you guys are getting.
We have a truly talented group of astrophotographers!

Anyway, you can see my latest shot of NGC6888 here:
https://www.astroshow.com/Nebulae/NGC6888.html
and compare with my earlier shots over the years...
40 minute shots are definitely better than 20 minute shots...

I have tried to shoot this object several times over the years starting with
Hydrogen-hypered film in 1998!  Hypered my own film using hydrogen cylinder
and 8% hydrogen gas from a semi-small metal hydrogen container...  :-)  Back
when there were articles being written that said "CCD will NEVER be better
than film!" :-)  And CMOS was unthinkable...

For what its worth, I will be at DSNM arriving 26 June and leaving 30 June.
If anyone needs me to do anything for them while I am there, AFTER I have
completed the tasks I have planned for MY observatory, please let me know.

(When I grow up I want to be able to process galaxy images almost as well as
Bernard...  Still going to be a while I think.) :-)

Thanks,

Howard

Thanks MUCH Bernard...

Shooting M101 tonight...  Will try to apply some
of your techniques but I think I will still have a lot to learn
before I can get within miles of your processing skill!

Thanks!

Not your typical open cluster - I'm guessing the reddening is due to its distance and location along the galactic plane?  Thanks for sharing it.

M8 - The Lagoon Nebula in narrowband

Bernard Miller
 

Hi,

 

This is an image of M8, also known as the Lagoon Nebula captured and processed with narrowband filters using the Hubble palette. It is an emission nebula about 6,000 light years away in the constellation Sagittarius. Its size is estimated to be about 110 light years by 60 light years.

 

Comments and suggestions appreciated.

Arp 91 consists of NGC 5954 (UGC 9904, VV 244b and others), the up and down spiral interacting with NGC 5953 (UGC 9903, VV 244/a and others) the distorted spiral to the right (west) of it. These are part of the ‘Spiral Galaxies – Companions on Arms – Large, High Surface Brightness Companions’ class. The newest study puts these at approximately 52 million light-years away in Serpens Caput. Older redshift distance estimates are nearly double.

 

NGC 5951 (UGC 9895 and others) is the nice galaxy at the bottom right.
