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