Hi gang I need some very small diameter 2-core black/red figure of 8 cable for my 3D printer - the sort of size that the small 40mm x 40mm x 10mm cooling fan needs. As far as I can make out, the external diameter is 1.1/1.2mm, which I think equates to a 0.2mm2 per core. No more than 1 amp rating - it is only running the small fan after all. Like this https://www.3dprinterspares.co.uk/2-pin-jst-to-2-pin-dupont-fan-extender-cable-90cm-133-p.asp but after a long length so I can make my cable to fit... I can't seem to get the right search spec into eBay or Google to find a supplier! Anybody have a link? I could ask the above supplier to see if they have a reel, but I suspect they just buy them as pre-made.. Thnaks!

Came across this thread while investigating exactly the issue the OP had, after ABE. Turns out the rear element on my flattener has come loose and had clearly shifted between taking the lights and flats! The flattener is now off for fixing, but wanted to give a shout to @Oddsocks and for a 3 year old thread!!

Wow, that's lovely Peter! I like the IC2574 (swirly galaxy, left of the blue star, to the left of M81) - but there's lots to look at in there!!

Excellent!!

Thanks Mark! I'm certainly interested in contributing data for this project! Perhaps we could organise a Zoom call to go into more of the details of actually contributing?

Thank you both! Found this interesting discussion - https://www.aavso.org/use-baader-rgb-non-photometric-filters as well. So, at least I can start measurements and keep the kidney! Thanks again!!

That is very very nice!!

So, starting to take steps in to variable star measurements,... I have downloaded the AAVSO CCD guide and will be working through that to measure my systems parameters (gain, e/adu, etc) and it comes to the question of filters... The Photometric filters are expensive, but also seem to be rarer then rocking horse poop.... It seems Baader have stopped making all their Johnson -type filters and are working on a set of sloan filters, but I can't see any info on when they might be available. So, is there an alternative to the V filter I can use while I sell my remaining kidney and good eye to pay for one?? I have the standard RGB/Ha/Hb/O3/S2 filters for astro-imaging at present... Cheers!

So, the flattener on the Sky-watcher ED72 has a male M48 thread. My Atik One OAG has a female T2 (M42?) thread. So far so good... What I am after is an adapter that will thread on the INSIDE of the flattener (i.e. a male thread) and then a male thread on the T2 side. Why, I hear you ask... It's the old 55mm problem. The flattener has a back focus of 55mm. My Atik One CCD sits ~28mm from the front of the case, and the OAG is 24mm deep - giving 52mm. If I use the M48-T2 adapter from FLO, it adds 10mm to the train i.e. 62mm. Which I'm pretty sure will be too much. So, me and my tiny brain think I need some sort of adapter that threads on the inside of the M48 thread of the flattener - but I don't know what size that is! Does any know what this may be - or have another suggestion??

That was brilliant - really interesting @tomato! Many thanks again!!

That was a great talk!! Just amazing to see and understand some of the unknown stories!

Three excellent images indeed! I bet that was a fun conversation at FLO!!

EQMod (EQASCOM) gives you the ability to set multiple park positions, set up different locations (e.g. home, observatory) with different lat/lon settings, set up a game-pad controller, play sounds when you slew/change rate/etc. It is a 'driver' - so the planetarium (e.f. Carte Du Ciel) uses this to communicate with the telescope.. You configure the driver to use the correct USB-SERIAL port, and then select the HEQ5/6 driver in the planetarium. Once connected, you can click and slew the telescope to any part of the sky, or manually drive it with a game-pad. Many of us with the Skywatcher mounts use it, so always plenty of advice here!

Just back from a different Kelling! Still enjoyable though, and good to catch up with people - suitably distanced of course! The 'party' aspect was certainly much reduced, but of course, understandable! Fingers crossed we'll get back to a bit more normally next year.... The skies on the Tuesday night were very nice - certainly darker than at home, and a short burst on Friday was showing promise but alas it was not to be! Still deciding on WinterFest, and possibly Spring.....

👍 Certainly is Carole!

We're here, and so far no issues. As you come in the main drive, there is a 'Security' chap who will tell you about the Check In Kiosk! On the layby, next to the car park, there are two Check In huts and someone will check you in there. Saves you going to Reception. Toilets and showers are cleaned more often, the main doors are left open and windows are also open a small amount, so we'll see how that affects LP during the week. The site was busy with non-astronomers but they are starting to clear out now. Not been to the shop or Forge yet, so can't report on those yet. Safe travels everyone!

@Tim - looking forward to catching up at a safe distance matey! If you're passing 351, say Hi!

That was great - really enjoyed that! And I forgot to say - if anyone is at Kelling for the Star Party, drop by 351 on the Red field and say 'Hi' (socially distant, of course!)

Also, try downloading USBDVIEW - https://www.nirsoft.net/utils/usb_devices_view.html - and completely clear down the instances of your camera's and try again.

Try Atik's own software - you can install as part of the Atik driver installation

From memory - it has been a while since I used mine - you don't set the guide rate, at least I don't ever remember doing so (but again, it has been a while since I used mine!) The exposure time is the exposure time of the guide star. The longer this exposure, the brighter the stars will be but the risk is that your target has drifted too far. MX RA = Max RA - the maximum correction that PHD2 will send to the mount - even if the calculated time is more than 2500ms (2.5s), it will be capped to this. I came across this wile trying to remember about the guide rate... http://www.octanslab.com/2018/09/01/phd2-guiding-with-star-adventurer-mount/ Will be useful for myself too!!

Grabbing the PI file now

That's awesome Michael!!!

Hi all On 15th July, I'll do a session on Sequence Generator Pro - predominantly aimed at new users for this first session, but if you have any specific questions you'd like me to look at and cover, I'd be happy to... I'll aim to do: Overview of the interface / menu options Profiles - User and Equipment Connecting equipment Set up a basic sequence But happy to be steered by you all! I'll then aim to do a 2nd session where we can look at things like plate solving, auto-focusing, framing and mosaic wizard, multiple targets etc. - or again, whatever you you would like! Wednesday 15th July 2020 7:30 PM BST. As usual it will be recorded!
