OK, yes I got your point. But mine would be, if you're an imager, and you don't have a calibrated monitor (Wide gamut optional), then why not?

I have a calibrated wide-gamut monitor and see the outer shells just fine.

Thanks Olly. Done a google search (D'oh) the nearest to me is Poole Islands, so Bournemouth way. A bit far to just drop in "on spec".

Hmm.... never heard of Decathlon outside the Olympics.

I've had astro darkness since the 17th

And on This page is the ASA information.

There you go again Rob. No reputable imager will ever "doctor" their images. They will, however spend many hours patiently teasing out the information contained in their data, often collected over 20-30 hours (Been there, done that) over many nights, sometimes even over more than one year (Done that too). In addition to the hours taken capturing and processing their data they will often have spent many years learning and refining their processing skills.

I'll watch it tomorrow, as I'm for bed.

OK, not in depth science, but not bad for a "Horizon" Did anyone else notice the PI desktop when they were combining filters. It was only a brief glimpse.

More in depth on Thursday

I seem to remember when I was looking at the Liverpool Telescope that they has several "H-alpha" filters with wavelengths adjusted for different redshifts.

Could have got Maggie and Chris to do it.

This an image from a few years ago. 2 mins each RGB with the Liverpool Telescope on La Palma

Maybe an IDAS D3 ?

I see that site lists the West Bexington car park. I can vouch for the darkness of the sky here BUT. I was talking to a couple of residents after a parish meeting and they said the restaurant has a bad habit of leaving lights on all night, so may not be as good as expected. Gorselands caravan site a hit higher up might be an idea.

It's a Horizon Which means about 15 mins of dumbed down drivel for the hard of thinking, repeated over and over. I think Dr Becky will have something more substantial.

You haven't said anything about guiding, that should be your number one priority.

Oh, and he's coming over here in September for a major tour, including Spaceport Cornwall

What I find really sad is that we have to find out about what we're doing in space from an anglophile American. We barely hear anything from our own press, even the Beeb.

10 pm, BBC 4 The sky at day, mostly about solar and what can be seen during the day. Also a piece about the Parker Solar Probe.

My plan is to start with 15 sec subs, then keep doubling until the histogram shows saturation, then dial the exposure back until I have bright stars (So the background stars show up) .

Possibly. I noticed a little elongation too. I may try another stack with more stringent limits for elongation, see how many subs are rejected. There shouldn't be any cable drag as all the power and data cables are routed through the axes, this is the most likely cause of trailing with ASA mounts. The PA is a bit further out than I'm really happy with, but I want to wait until I can start earlier in the night, as trying to deal with technical issues when I want to turn in isn't conducive to good outcomes.

Thanks Carole. There may be a clear night tonight, if so I will try a few single subs to see how the histogram looks. probably start at 15 sec and double it until I get saturation, then dial it back a bit.
