A coloured rosette


Recommended Posts

Just got round to processing this one from early December.

Not the kind of image I specialise in, but it was a good subject for my recently-acquired 2nd hand Skywatcher ED80 plus 0.63 focal reducer. False-colour narrow/broadband with H alpha mapped to red, OIII mapped to green, and blue mapped to blue, with H alpha also used as the luminance.

Further details on image.

Welcome aboard SGL David.

That's an excellent false colour image of the Rosette. Plenty of exposure time and good processing.

The ED80 is certainly a good little imaging scope for the money.

What sort of images do you normally specialise in then ?

Thanks for the comments, and thanks for the welcome.

Yes, I have been really pleased with it. The only slight problem I have found is that the 2" drawtube is quite loose on most accessories, and the placing of the setscrew very close to the end doesn't "agree" with some adaptors with safety undercuts. Mine is the older type with the blue tube.

Planets in high-res, a lot of those on my website. Comets to some extent. The faint objects are a problem from my very light-polluted site. Narrowband images like this are probably the best method of dealing with this.

Wow, just checked out your webpage - there are some stunning images in there - I particuarly like the Saturn images (you sure you haven't got shares in Cassini).
