At the moment Friday and Saturday look cloudy on all 3 sites, but Sunday looks as though there could be some clear sky in the early hours, on 2 out of 3 weather sites, but this is no good to you guys who have to work.

Final decision tomorrow morning, but it's unlikely to change sufficiently in 24 hours.

Astrophotography / Re: NGC7822 HOS with RGB stars etc

Thanks Noel.  I am going to possibly write adding RGB stars to a NB image as a tutorial, or maybe when I am feeling a bit more confident in the work flow, do a video tutorial for it.

I tried a combination of the tutorial I had before and Roberto's tutorial link and added RGB to my M16 I did last year.  I often take RGB to add to NB images, but only sometimes manage to actually use them.  In the case of M16 I found RGB but had never added it to the final image.

Now added

Isn't the South Downs International Dark Sky Reserve closer?

further away from light domes like brighton/worthing the better.
cranborne chase is far away from LP like all the towns straddling the south downs.
Going by the dark sky map.

Looking really good Roberto
I make it 9 or 10 galaxies in one picture.

Well done.

That's a shame Julian, just when you managed to get organise.

We will keep an eye on the forecast and decide by Thursday morning the latest.  Watch this thread.

That's come out well Roberto.  Looking forward to trying out that Idas Hutech filter you recommended this winter from Home.

Thanks for the tutorial Roberto.  there was at least one aspect of that which I wasn't doing which will help and that is reducing the whiteness of the NB stars before adding the RGB stars and this explains why blend mode lighten wasn't working.  Another tutorial I got was to use a clipping mask and blend mode colour to blend the RGB stars.

Will plug away at this and hopefully eventually will get something that works well.
