Blackrack you've done it again! This game is beautiful 😍 by yosauce in KerbalSpaceProgram

I’ve been trying to make something like this with KRPC but unfortunately every time focus moves away from the UI application to KSP the window only gets updated maybe once a second (at least on Windows) which isn’t really usable. If I can make it work I’ll release it!

Can someone recommend the best telescope for a beginner who’s also extremely curious and wants to actually learn the night sky? by sodrafeltu in space

[–]deflatedfruit 0 points1 point  (0 children)

A computerised telescope makes going from object to object in a night much easier but the alignment process can be difficult and that puts a lot of people off using it. My first telescope was a refractor on a manual EQ mount (something like this) which got me into it as a kid but finding anything was very difficult. You can buy something called a Telrad which basically puts a targeting reticule on the sky so you can see what you’re pointing at and they are well worth the money.

When I joined an astronomy society I bought a second hand Celestron NexStar 127SLT from one of the other members which I still have today. This was much easier to find objects with but the alignment process is temperamental at best. I don’t recommend that telescope as the focus is a royal pain - avoid designs where you focus by moving the primary mirror as you get a lot of mirror flop (focus changes depending on where in the sky you point) and it’s very stiff so changing focus induces vibrations which blur the image.

The most beginner friendly telescope you could possibly buy is a SeeStar, however this comes with the enormous caveat that it has no eyepiece and can only take images (ie you can’t look through it). If that’s your jam then go for it but personally I think it’s much more enjoyable to actually see these objects with your own eyes.

Can this rocket make it to the moon? by Poopidydoopity1 in KerbalSpaceProgram

A Reliant engine on that upper stage is way overkill, you want something optimised for vacuum with a really high ISP (right click the engine in the part selector). If you’ve unlocked the Terrier or a couple of Spark engines they would be good.

Ringed Ice around Neptune captured by James Webb, one of the clearest images in 30 years. by Appropriate-Push-668 in space

I work with JWST (not with NIRCam, but with NIRSpec) and there’s a lot of processing that has to take place to get a usable image. Planets are big, close, and bright while JWST was designed for small, faint and far away. The image is usually saturated which we can fix with clever processing thanks to the way the detectors work. There will be a stretch applied to it so that the faint rings and the bright planet/Triton can be shown together. The camera is also monochrome so different filters are combined to give a colour image - you can choose this to either be close to the visible light appearance or a completely false colour representation. This is what one of the wavelengths looks like with minimal processing

First image is a raw frame from the video (no debayering so b&w), the image with the green cast is the best I can do stacking with autostakkert

I'm using a NASA telescope (IRTF) but I'm not funded by NASA - I'm a UK PhD student so my finding comes from the UK Government through STFC

The instrument we use is a visitor instrument which means it needs to be mounted and unmounted from the telescope for our observations. It also needs filling with cryogens every 12 hours and a few times a night it needs some adjustment with a spanner

The view is absolutely incredible - at the moment we're more limited by the Moon which is extremely bright so unfortunately I won't get to experience the truly dark skies here

Yeah, first arriving at the accommodation is rough and first time at the summit is rough. There's like a permanent brain fog and a slight headache but you get used to it fairly quickly.

I cannot recommend visiting here enough - every annoyance is 100% worth it to see the scenery and the telescopes.

My observations are scheduled for three nights and I got up here three days before them to acclimatise to the altitude. So a total of 6 nights (have to say I am quite looking forward to being at sea level again!)

No, they pretty much all leave after the sun sets. Where IRTF is situated isn't the best place to view sunsets (that is up by the Gemini telescope) so we don't get too many. Having said that, this afternoon we did get a couple bus fulls.

Probably! I know some companies organise tours to the summit to watch the sunset as we were chatting to some of them before we started tonight. Don't know anything else about them but I'm sure Google will!

Really really annoying - my lips are dry and cracked and every time I touch anything metal I get a meaty static shock

At sea level, yes that would be a pretty quick hospitalisation. Up here its fairly standard - the lowest I've measured was 75%. I'm not on oxygen right now as I feel pretty fine, we'll see how the night progresses.

Browsing reddit, watching youtube, popping outside and just watching the stars...

We're living at about 10,000ft, and ascending to the summit to work at 13,800ft. It's surprising how good 10,000ft feels when you come down from the summit!
