Yes, it's just a touch out, but I've found that "just a touch" can make the difference between nice sharp stars and a soft bloat.

Yes, I thought it was a good episode, the highlight being Dr Becky. I wonder if we'll be seeing more of her on S@N?

Nope, clouded out for the foreseeable.

First up, full disclosure: I am pretty much 100% imaging. I often read posts by the visual astronomers talking about the "thrill of the chase" when hunting down faint fuzzies which are only a fuzzy grey, but for me (And, I suspect, a lot of imagers) the "thrill of the chase" comes after the data is on the computer, calibrated and stacked, and trying to tease out and reveal some faint tidal tails around interacting galaxies that might be barely above the background, or diffuse nebulosity that is just barely there.

UFO / UAP could be these guys doing something practical at last.

Yep, I found it watchable too. Will be watching part 2.

I think the vignetting would be far too extreme for flats to correct. But try it and see.

Looking at the ad, he's including an LRGB filter set, so even more of a no-brainer.

Yep

Something like the Musha Jump Drive? Gotta love AstreronX. Mad as a box of frogs but entertaining, provided you don't take them too seriously!

I won't believe it's aliens until I see demonstrably alien technology and / or equally non terrestrial remains.

I measured the clear aperture of my Baader 1.25" filters at 28 mm, so too small. I would seriously consider going to 36 mm unmounted if you can.

I duuno... Had another play with this through PI and AA8. SCNR in PI, then DDP, residual magenta removal, and curves in AA8 Still not happy.

Thanks for taking the time and trouble over this. I'm going to take a pause, have a think, and come back with fresh eyes.

Hmm... I may have left too much green in the image when I was taking it out as I wanted to avoid sending it too red. I may have another go. I'll have a go with ABE to see how much vignetting there still is, I thought the Flats would have taken care of that. I ran NoiseX but kept the level to 60% as I didn't want the background to go too "plasticky".

No, I didn't try starless processing, as that's something for me still to get to grips with. I used several iterations of the "Attenuate One Colour" tool in AA8 with careful note of the processed areas, as the original image had both too much green in the target area and a huge magenta area around the outside, plus the usual magenta stars.

Toil and Trouble, much of both! This data was captured on 5 nights between the 22nd June and 19th July in 900 sec subs with the ODK 12 / G3 16200 combination with 3 nm Chroma SHO filters. 12 Hydrogen, 16 Oxygen, and 16 Sulphur subs made it into the stacks after chucking out the worst subs. Calibrated with Pre-calibrated Flats and Darks. Initial SHO combination and cropping in AstroArt 8, then into PI for BlurX and NoiseX, then back to AA8 for DDP and colour adjustment Saves as a JPEG I'm still not happy with it despite spending many hours bashing with the heavy hammer. Given that I'm out of practice with NB (Been concentrating on galaxies for the last year or so) any advice will be welcome. Thanks for looking.

As here. I joined Rory's Discord and tried to participate but it just got manic and I had to drop out as I couldn't keep up.

I'm lucky in that I'm a) retired, 2) an imager, and 3) have an automated obsy. So I can set up an imaging sequence, check that it's running, and then turn in. I may wake up to shut down the obsy after the run, but I have woken up at 6.30 in winter to shut down, which I can do from my tablet without having to get out of bed. Lazy? Yup 😂.

I'm in the Bride Valley not far from Bridport. I have Bortle 3 sky.

Hi Kriss and welcome to SGL from another Dorset astrophotographer.

I still remember one early December a couple of years ago when I went out at about 4 to lock up and the sky was pitch black and glittering, with the clusters in Auriga like gems. Triangulum and Andromeda were still quite high in the west. M31 was huge, and I noticed a faint grey fuzzy that I only later twigged as M33, seen directly without needing averted vision. But I was only wearing my dressing gown so didn't hang about too long.

It's a home built RoR that just looks like a shed. But it has automated roof opening and closing.

I have a completely automated obsy thanks to the ASA software. I can turn the power on remotely too, so I can set up a sequence and go to bed, closing down when the sequence is finished without even getting out of bed.

When Betelgeuse goes bang (Or rather when we see it go bang) two things can be guaranteed, a) it will happen in summer, and b) we'll be clouded out for months.
