M20 & M21 - Hybrid Image

[Martin Pugh]

Good evening.

For this image I have combined previously acquired 12.5" RCOS tri-colour NB data with data captured over the past several nights using the RH305/STXL16200. Intent was to retain the much higher resolution core of the Triffid whilst adding M21 and the abundant Ha in the region to the overall field of view. It didnt take much with such a fine, fast instrument - just 3 hours Ha and 5 hours OIII. Note that the blue nebulosity surrounding the Triffid is OIII. Finally, I added just 20 minutes each RGB for star colour.

Also - new website to boot - but very much in its infancy as I continue to populate it.

Splendid work :thumbsup::thumbsup::thumbsup:

M21 adds a lot to the image.

Hadn't fully appreciated that there was such an OIII halo around M20 before. In RGB images it's lost in the reflection nebulosity.

The fine detail in the dust lanes is great.

[Stevec35]

Nothing much to say except another great image Martin. I also was surprised to see the OIII halo.

Cheers

A really interesting take on this object Martin - and quite appealing! :thumbsup: Is it possible to show a higher res version though, to appreciate the finer details?

Like the new website BTW. :thumbsup:

Fabulous image Martin. A fresh look at a familiar object.

Greg.

First rate, Martin. Very different and as mentioned earlier, that Oiii was a bit of a surprise.

Triffid itself has great depth,:thumbsup:

Very interesting to see the O3 data. Very nice.
Cheers,
Tim

Many thanks everyone.

Marcus - I am still getting the hang of the new website and just need to figure out how to configure to present a larger image when clicked upon. Plus, my upload speed is a ridiculous 384kbps (is this 2017?) so you can just imagine how long it takes to upload a single, large scale image.

cheers
Martin

Looks fantastic Martin! The Honders +16200 are looking to be a fantastic match :)

[Paul Haese]

I reckon the scale of this image certainly detracts from the image I have seen of it. Though like I said then, you are the master and the image is beautiful. Detail is great. Unique view of this object.

[Martin Pugh]

Thanks again folks.

I have actually uploaded a higher resolution image to the website now.

cheers
Martin

Sublime - the best NB/Broadband version of this object I have seen, a big winner both technically & aesthetically. :thumbsup:

Would love to see a larger version though :D

[Slawomir]

Mesmerising. One of the most inspiring images I have seen this year.

[Martin Pugh]

Thank you very much indeed.

Alas, Squarespace website only allow an image with a maximum of 2500 pixels in one dimension. So, when you click on the image that is all you get, however, if you then 'right click' on the image and save it to your desktop you are at least afforded the opportunity to zoom in, which you cannot do from within Squarespace websites.

all the best and clear skies

Congratulations on the APOD Martin: https://apod.nasa.gov/apod/astropix.html

[Martin Pugh]

Pete - thank you.

I am obviously very pleased given this is just the second image out of this scope since I relocated back home (third all up).

cheers
Martin

[Atmos]

Congrats Martin!

[mountainjoo]

Very unique and revealing presentation, congratulations on the APOD.

[Slawomir]

Awesome news, congratulations Martin :thumbsup:

[Martin Pugh]

Thanks again. Very much appreciated.

[gregbradley]

Congrats on your APOD as you say with a new scope as well.

You must be the most APOD`d astrophotographer - is that right?

Plus its great to have you on this forum and you freely give your help.

Greg

[Martin Pugh]

Good morning Greg and thanks.

There are a good number of far more accomplished astrophotographers than I. Search the archives for none other than David Malin (80+), Gendler(120) and Block (161). Those are just 3 names that come to mind!

On top of that, folk like David and Rob I would consider as 'pioneers' in astrophotography. I just learned from books, practice and experimentation.

Cheers
Martin

[Peter Ward]

An APOD to boot.

Too good. :thumbsup:

[LewisM]

That's rather good! VERY appealing twist on the usual.

Agree though - ditch the small version here, it just looks odd. The larger size/resolution is, well, POP!

[cazza132]

Awesome image Martin! And congratulations for the APOD!

[Martin Pugh]

Thanks again folks.

Congrats on the image and the APOD, Martin!

[Martin Pugh]

Thanks very much Rick. Been away?

[RickS]

Quick work trip to the US, Martin. Alas, little free time to keep up with astro stuff.

[RobF]

Fascinating take on an old favourite. And congrats on another APOD Martin. :cheers:

[topheart]

Hi Martin,
APOD congrats!
Cheers,
Tim

[Martin Pugh]

Thanks Tim/Rob

Clear skies

[codemonkey]

That's stunning, Martin. Haven't seen a NB trifid that I've liked anywhere near as much as this one. Very well done!

[Martin Pugh]

Thank you Lee!

Cheers
