Hi, This is a video posted by Scott Manley. It's a 360° VR representation of a wormhole. Just pan the video if you don't have a VR headset.

After 12 minutes of examples of nothing being ordinary, I get the feeling that not being ordinary is quite ordinary.

Wonderful and they're 10x50 too! Happy observing.

Hi John,

Very excellent!

I think it's beautiful.

Amazing quality and quantity!

If you google for 'fungus on mirror' and you find that the images you get resemble what you see, then indeed, you probably got some fungus growing on your mirror. Keeping a mirror in a garage is probably a bad idea. Still, clean the mirror with a disinfecting agent (alcohol and propanol work - the two active ingredients of Baader's cleaning liquid). The spots may improve a bit and at least won't keep growing. After that, keep your mirror in a dry place and also avoid places that have a combination of (occasional) large temperature drops combined with (occasional) high humidity. It's also a good idea to use a hair dryer to warm up your lens, corrector plate or mirror after bringing it in.

Well done Craig! Excellent images!

Hi Syn,

You are probably right. There's also the possibility for a good Barlow to reveal the CA of a refractor (do you use a refractor?) but the way you describe your Barlow, I suppose it's the Barlow that is to blame.

Hi, welcome. What you saw was the shadow of the secondary mirror. That happens when you are way out of focus. You tried to use the focus knob as a zoom knob. It can't zoom though, only focus or blur. When you reach focus, blur is minimal and the planet will look as small as it gets through the telescope (same for stars: sharper is smaller). You'll see that Venus has a gibbous phase, slight more than half. --- The Moon was out. An easy way to test if you are focused properly is to have a look at the Moon: if that is sharp, the rest of the sky should be too. For practical purposes everything out there is at infinity.

Hi Sloo,

Bravo! It's a beauty.

Fabulous sketches, Mike!

Gee, that's a shame. Sorry that happened!

You probably tried the entire range of the focusing knob. Maybe the mirror came loose from its focusing mechanism.

To get to know the sky is a wonderful thing. Congratulations on your discovery! Do You already have Stellarium? It's a wonderful tool. It's free. Get it from Stellarium.org

Oh, the link is to a screenshot of your order. I know nothing of these things, but thought I'd show your order. Welcome to the site. There will be members along to have a look at your prospective items!

Fine weather on Mars allows a grand view of the planet. I'm so much looking forward to a good opposition. Excellent work, Avani!

For any given eye relief, with a larger apparent field of view you need a larger eye lens, and with a larger eye lens you get a bigger eyepiece. On top of that, large eye relief eyepieces often get longer with decreasing focal length. That is because they require a stronger first, negative group. --- The Delites are petite, the Morpheus are lightweight and the Delos are heavy. You found the XW. There's also Nagler type 4. That's about it for the top shelf long eye relief choices.

101? Well done! And thanks for the calculations. A lot depended on it.
