OK, so an easy subject, but I was keen to see what the little refractor could do. About 5 minutes after this the clouds, and fog, rolled in. Maybe another night.
Zeiss ED80/840, with .75x Mewlon reducer (thought I would try it), Nikon D100 @ISO1600, one four minute shot. Minimal levels tweak in Photoshop, and downsized for posting.
I will try other targets once the weather comes right, and the moon naffs off.

Showed it to a newbie at our club night last night, high WOW factor, especially when you explain they are looking at 5 Mil stars !

There are constant debates about this versus 47 Tuc. This is my favourite as well, but both are wonderful.

Thats a beautiful image, I like the zoomed back view of this globular more so than the closer ones.

Thanks Andrew. It's a fact of life at 840mm reduced additionally by .75x. But it makes exposures a bit shorter, and guiding a little less critical.
I intend trying other targets with this wee scope as well.

One 4 minute shot you say Gary?At 1600 iso with minor processing?Thats a REAL nice shot. Did you get much noise or has processing gotten rid of most of it?

Thanks guys.
Robin.
The D100 (as you know) was used with the N/R setting, and no, all I did was resize it to fit, and also slightly levels it.
Louie, I did think to leave it just as "ED80" but after all the money I sepnt on this puppy I want to show it off. It normally gets left inside, as it is as heavy (almost) as the Mewlon, and only 80mm as opposed to 180mm. For CCD imaging though it is nice.

Nice shot Gary. Well centred. Just curious as to why your D100 always seems to produce blue white stars and my D70 seems to produce Yellow white stars. Very strange or is this just a result of processing?
thats a great shot. I too like the fack that its not a close up. looks nice and dense (like me :P)

Paul,
no idea, and I seriously doubt processing, as levels and minimal at that was all it got. Resized of course from a couple of mb.
I wonder if the white balance has anything to do with it.

Could be white balance Gary, Might have to check that my white balance is set correctly. That might account for the reason that my shots with lots of red like nebula have high red showing, which does not traditionally seem to be the case with the Nikons.
I get back to you when I know.

Very nice image. Kinda reminds me of Omega at 60x magnification in my C6 (only alot less bright..in my scope I mean). I just love this glob!
