Rosette in ZS66

[ollypenrice]

Having spent so long getting the Ha for this, but being unhappy with it, I none the less had another look this afternoon and think this is a better one than I posted earlier. The earlier one used Luminance as well as Ha, this one Ha and RGB only.

Sorry about the username mixup, everyone.

Lovely Olly - what camera did you use on the 66?

Thanks,

Richie

[ollypenrice]

Thanks, Richie. I used an Atik 16HR mono, Baader's basic colour filters and an Astronomik Ha. The setup woud do a lot better but there was a fine high haze. I don't know what others think but this seems to clobber the green hardest of all. I had the dedicated FF-R in the 66. No darks or flats. I never take them but do use the hot pixel zapper in AstroArt.

Thats really nice Ollly.

So does this Hot pixel zapper eliminate noise, similar to taking lots of darks and subtracting them?

[ollypenrice]

Not quite that clever, Mick. You set a threshold and the programme recognizes what are probably rogue pixels and, I suppose, gives them an value like their neighbours. I use the default setting.

It stops the odd little run of hot pixels stacked up like a staircase on the frame. I don't often get that but it's tedious when I do. The hot pixel filter seems spot on for stopping this. You can get orgaized and create a hot pixel map, too, in AstroArt. I just haven't sorted one out.

Interesting.

I have seen that hot pixel ladder on a few photo's.

Thanks for explaining it

Excellent shot Olly. Loads of detail and the colours are very good, Trevor

Crikey Olly, is it ever cloudy at your place? That's an awesome image!

[Psychobilly]

Excelent shot Olly...

Still havent managed to get any decent data for this one I have got 2 hours of out of focus subs...

DSS also has setting for cleaning up hot and cold pixels in images... its in the satcking options cosmetic section.

Lovely image Olly, I'm collecting subs on the Rosette ATM and I hope my image turns out as good as yours

[ollypenrice]

Hi George,

I'm out there too, still with the ZS66 but on M42 and the Running Man. Good luck with the Rosette. What a lovely object. You can see it visually here but only the Genesis will fit it all in.

Which scope are you using?

Olly

PS Give my love to Stockport. I went to school in Bolton..some time ago!

[George]

I'm using the ED80 for imaging, just about squeeze the Rosette in the FOV....not a chance ever seeing it visually here

[Starjumper]

Nice capture Olly.

Great stuff Olly.

Interesting what you say about green being affected first by high haze.

Cheers

Very nice Rosette Olly, good to see the F.O.V. with the ZS66/0.8 flattener/285 CCD combo too.
