Eastern Veil

Hello,

I'm trying to make a 8 tile mosaic of the Veil Complex! Since I had only one night to make it all....I only got 30 min of each tile in Ha. The mosaic is under construction!

I managed to get 30 min of OIII data too of the Eastern Veil (NGC6995), the first piece of the mosaic. So I made this RGB of it with only 30 min of Ha and OIII...so no great stretching possible!

All data captured the full moon night (30th of august)....

Tak FS 102 NSV @ f/6.3 + QSI532WS-M1 @ -15ºC

2x 15 min Ha; 2x 15 min OIII

RGB as HaOIIIOIII plus green ch tweaking!

Cheers,

paulo

Nice one - but I couldn't resist the challenge "no great stretching"....

I cropped this first because the top and left hand sides showed "fading" due to mosaic(?) stacking. It's come out with the colours a little more muted and more detail on the fainter nebulosity. There's probably a bit more available but I didn't want to overdo things :)

Hi,

thanks for all the comments!

Now that I'm in another LCD/computer the color seems strange compared with what I "saw" yestarday in my laptop!

I really need to calibrate all my LCD screens!!!

It is why I should have a maturation period before posting images :-). First processing....wait a couple a days and then go to see! Usually it will be reprocessed :-)

There is a little more signal in Ha as you will see...but do not forget that I have to handle the OIII too (taken with the full moon and only 30 min of it!!!).

Squeaky, I do not like the GREYCstoration effect ;-).

Cheers,

paulo

Pity you couldn't get it all in otherwice it's pretty good. Is this because the camera sensor is too small to cover this object? This is one reason I'm really pushing a DSLR - I can't afford a decent size CCD astro camera and there are a lot of quite large but faint DSOs I like to image.

As for the colours (as has been mentioned above) I prefer more natural colours - in a colour sensor it shows as red and slightly blueish green.

Hi,

maybe is my screen...:-)

Yes Gina, my sensor is only 18 mm in diagonal so with my 641 mm FL I have not that much of FOV!

But here we say "who have no dog go hunting with a cat" :-)

The more I look at it the less I like it, which is great! I will reprocess it soon (today was the mosaic construction day :-))

Cheers,

paulo
