Hi Bernard,

Truly magnificent!
Your processing is, as always, superb!

Thanks,

Hi,

 

This is an image of M8, also known as the Lagoon Nebula. 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.

Good job, Howard. I can see the fainter regions that complete the circle.

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

Howard,

Nice image. Keep up the good stuff.

You mentioned that eXcalibrator fails in this region. Are you using the
latest one (6.2?). I loaded my RGB which looks to have a similar field of
view and it uses 86 stars with APASS >=2 observations which is the default,
I think. I get 72 stars if using Pan-STARRS. There doesn't appear to be
coverage in the SDSS-DR7/9/12. I'm thinking maybe you have an old version.

Re: Crescent Nebula (NGC6888)

Thanks Bernard and Dan,

I used the latest eXcalibrator.  I just tried it again
and changed some settings so SExtractor was selected
and so APASS button ungrayed and it worked!
THANKS for indicating that it would work if I did it right!
I had sort of given up.

Fortunately the color correction factors were that I used
were VERY similar to the ones I got last time when I used earlier
version of eXcalibrator so I think the colors are pretty close.

Thanks VERY much Dan

Re: Crescent Nebula (NGC6888)

Dan Crowson
 

Howard,

I think the colors look good. I was just mentioning it because (when you image as much as I do) there are times when you run into the lack of stars if you're not using APASS or Pan-STARRS. Off the top of my head, I think APASS covers just about all of the northen hemisphere sky.

Smoke Effects?

Has anyone seen any effects of the AZ smoke in their DSNM imaging?

Brian

 

Re: Smoke Effects?

Dan Crowson
 

Brian,

 

I have not but we’ve had a few nights of ‘clear’ skies that have not been real clear. It is hard to tell remote but I could tell right away here at home and it was real obvious because the background ADU would be very high (at least twice normal).

M8 - The Lagoon Nebula in narrowband

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.
