Pickering's Triangle in HST palette

[Paramount]

Hi All
I have been doing a project of the three main components of the veil nebula complex in narrow band and have recently posted NGC6960 (Witches Broomstick) here, I have finally managed to get sufficient data for Pickerings Triangle which I started over 2 weeks ago when I managed to get the Ha and half of the OIII, last night I managed to get the rest of the OIII and the SII data. It is 21x10 minutes for each filter and the HST palette is used so SII=Red, Ha=Green and OIII=Blue. It was taken with a Takahashi BRC-250 and Starlight Xpress H36 with 12nm Astronomik filters on a Paramount ME autoguided with a Starlight Xpress Lodestar/TMB 115 combination, dithering was used in Maxim DL. Both nights were hampered by thin misty cloud in the upper atmosphere which may account for the noise still present in the image. The NGC6960 image can be seen on the Nebulae 2 page in the image gallery of my website http://www.imagingtheheavens.co.uk. On to NGC6992 now (weather permitting), thanks for looking
Best wishes
Gordon

Pretty neat Gordon. Stars are a little bit overwhelming IMO but I love the contrast and colors you got in the nebulosity. Top work.

Hi Marc
Thanks for the comments, good point about the stars, there are a lot of them aren't there, I suppose this is the problem with imaging, we don't realise just how many stars are out there until you start stretching the image

Very nice Gordon. Loads of fine detail but not sure about the colour scheme. Not my bag but each to his own. The detail and overall image is great.

The trick is to sretch the nebs without touching the stars. DDP will always blow up the stars so you need to isolate them. There are a lot of different techniques in order to do this depending on the pictures and original colors.

Gordon,

Wow, I'd never heard of this object before.

You've done a nice job there -- it looks 3D on my screen.
