Wonderful image Peter, the nebulosity behind the HH reminds me of ocean waves rolling in with the spray coming of the tops.

Lovely depth as well, very fine work.

Cheers

Pretty cool. Looking at it, it just reminded me that I need to keep adding data to mine too. I've got already 4h on it but not even close to the details you're getting. Top stuff.

Thanks Marc (& RB and Ric). What camera are you using?

Great image Peter. A classic.

Did you use Photoshop to blend in 2 scope's data or Registar? Gendler often used multiple instruments and so does Thomas Davis.

I have a lot of older data now I'd like to blend in with newer data when useful. I was thinking of Registar.

Self guiding with Ha? Do you use fairly long guiding exposure times?

Greg.

I use a QHY8 cooled CCD 6MP on a Celestron Nexstar SLT 130. Here's my current attempt to date (just a bit over 4h from Liverpool) still noisy though.

Excuse my ignorance Marc...but is it a colour or mono chip? . (their web site indicates it is colour....in which case the result you are getting would be normal, as very few pixels are gathering h-alpha light)

Weeeeeell... if you notice Marc, as good as it appears to be, Peter has only posted his version at half the size of yours, your image is excellent and would look juuuuust about as good as Peters at 1600 X 800 also, I am sure.

You're right Peter. It's an OSC so I keep only the red channel and because of the bayer matrix RGGB the red looses a bit of res when resampling. Your pic is really crisp. I wonder if binning 2x2 would be better coz I know it gets rid of the bayer matrix and I end up with approx. 1500x1000 pixels pic. But then again CCD Stack debayering is supposed to compensate for this and minimise the loss of resolution.

Ah knew some badgering would win in the end

I take it that's the FOV you enhanced with the 14.5" RC data from last year?..can see the diffraction spikes .. not that there is anything wrong with that though, looks good

Ok baby steps huh?...we want the whole shebang man, comon post the lot, let us have a swim, promise not to steal the data and use it, promise... dare ya

Picked it in one.... (that data is 2 years old now).... the spikes were problematical, hence there is only a smidge of layered data there (about 10%)

As for the whole shebang..... Nah... you'll have to wait for the 16x20 print
