Hi everyone

The EKOS scheduler did everything from starting by plate solving a reference frame and slewing to its centre 90 minutes before the meridian, guiding, the flip, re-centre and another 90 minutes after. Monitored via TeamViewer, we returned to find a neatly parked telescope with the job done. Recommended:)

Had a quick google image search for the colours but couldn't find consensus; it seems anything goes. Maybe it could stand sharpening...

Thanks for looking and any comments as always most welcome.

Nice. 😉

Very nice image there, always one of my favourite visual targets in the 18 inch. I keep thinking about this auto capture but feel I enjoy being outside, at least I can't hear my wife shouting at my son to go to bed.

Very clean, crisp image. Star colour looks credible, too. The nebulosity showing as green in this image comes from OIII which lies on the blue-green border (sometimes referred to as Teal blue) so you're probably on the green side if anything.

Hi

You still have the choice of being outside, just not necessarily next to the telescope;)

Have never had chance to look through a telescope of that size. Can you see colour?

Well you can by virtue of the Olll filter, about the only thing you can see real colour in is M42, I have never actually seen the Vail without a filter but understand it can be done.

Agreed. The OIII filter made it very clear and very green in our 20 inch but it was also visible without. No natural colour for me though, not even in M42.

Always feel I see a bit of bluey green in M42 Olly, which must be wrong judging by photo's even I have taken. Can't say I ever pick up the veil without filter, must try again with a lower magnification though on 1980mm X48 is about my lowest.

Hi everyone

We removed the fat star frames and in an effort to get more green blue, stacked what was left with 6 more 8 minute frames with a UHC filter. It's done little for the green-blue, but intensified the red quite a bit...
