I've got one and that works fine. I use an 18m mains extension reel with an RCD on the mains plug itself. There's only a tiny bit of reel left when unwound. AFAIK because we live in the UK, I doubt it'll ever overheat, I had that worry but I found even when it was inside and I was taking dark frames for hours in a room that was about 15 degrees, it never got that warm at all, although saying that, not everything was running, just camera and RPi. I guess it depends a lot on how much power you pull

Had another shot at this data. Tried to not go so hard on the saturation this time and tone down the Ha a little as not to overpower the image. Zooming in really shows off the core and I focused on the dust lanes more as well. Workflow all done in PixInsight. RGB and Ha: Crop - RGB Combine with Ha - DBE - PMCC - 0.5x SCNR - TGV - ArcSinStretch Lum: Crop - DBE - Decon - TGV - ArcSinStretch - Starnet - Curves - LocalHistogramEqualisation - UnsharpMask LRGB: Linear fit Lum with RGB - Combine - Curves - Saturation - Export Edit: Brightened background slightly and galaxy

There's not much noise at all but mure denoise works with the sensor's characteristics to perform noise reduction using sample flats and dark frames. It can often give nice results if used correctly.

I think a great idea for those who want to use MureDenoise in PixInsight for linear noise reduction would be to provide the stats by taking a flat and a dark for each filter then using MureDenoiseDetectorSettings script

Cheers, Grant. Seems much better now, no need to apologise Matt

Second full attempt at the data which I've just finished. May edit when I do incremental upgrades Matt

First attempt at this data. Again, really clean so thank you FLO and IKI. I did have a slight issue with the Ha in that I couldn't get rid of a gradient that's faintly present in the image. Things to work on next is trying to not destroy the star colour but I'm happy with the rest Good luck everyone!

Just wondering if anyone else is getting issues with a radial Ha gradient? I can't seem to get rid of it in DBE at all

Someone's selling one on a Facebook group if you have it

The Soul Nebula in HOO Acquisition: Ha: 48x300" @ 139 Gain 21 Offset OIII: 57x300" @ 139 Gain 21 Offset Edited in PI

Do you dither?

Thanks, everyone!

It isn't actually, just one whole frame! Thank you! I live in a bortle 5 although there are quite a few LED streetlights around and yes, I'll certainly be adding OIII and SII once the Moon finally disappears

How does all of this sound? https://www.rothervalleyoptics.co.uk/mercury-138v-15a-bench-top-power-supply-unit.html https://www.firstlightoptics.com/astronomy-cables-leads-accessories/lynx-astro-silicone-power-cable-25mm-dc-jack.html (Ring tongue variant) https://www.amazon.co.uk/Dri-Box-FL-1859-285-Weatherproof-Black-Medium/dp/B00D7DU6YW/ref=sr_1_5?crid=17J8AUOD94C5W&dchild=1&keywords=ip55%2Bweatherproof%2Bbox&qid=1608636293&sprefix=ip55%2Caps%2C160&sr=8-5&th=1 Mains extension plugged into an RCD plug reeled up the garden to the PSU in this IP55 box and outputted through the 2.5mm cable into the DCHub 2

That'd be great if I could take a look. And my extension is almost fully unwound, I think about a meter just maybe 2 is left over

My issue is that I have to image further up in my garden and then I'm not close to any sockets. My mains extension runs about 16m to the equipment as to why I need such a long cable but if I can have the PSU in a box outside, with the mains extension running to it so I can have a shorter cable and not have significant voltage drop, that would be great. Of course, the scope would never be outside when it's about to rain and it takes me around 15 mins to pack everything up. My main concern I guess would be moisture and how that could affect the PSU, as well as heating issues being inside a box Matt

Thank you all for your input. How unrecommended is it to put the psu in a box outside with the equipment connected to a mains extension lead and have a 2-3m wire to the DSD DCHub? Matt

The cable needs to be about 16-17m. I have the HEQ5 running at 12v 3A max, 1600mm at the same I think, raspberry pi 4 and a dew heater. It has the black and red terminals. I can power the dew heater separately if necessary Matt

I'm basically a dummy when it comes to electronics and because I'm having communication issues due to a power brick, I'm wanting to get a 13.8v bench supply but I have no idea how to get from the black and red terminals into a DC cable for my power hub. Can anyone help with this? I was particularly looking at a mercury 13.8v 15A supply Also the power hub I have is 12v 10A rated. Does it only pull however much it needs and 15A won't be too much for it? Matt

My best guess would be to extract the green from every single one using a program then using AIJ with those? I saw your other post, maybe I can look at your csv just after your multi aperture and see what I can come up with? Also I could look at all of your data myself if you upload the files?

I'm having this exact issue. Did you ever solve it blinky? I'm running it headless on a RPi 4 so I'm not sure how to change usb port settings on Linux

Congrats to all the winners! Fantastic job

Last attempt(s) before it ends

Why would they bin it in the first place?
