Nice easy to read modeling. Thanks! Are you still looking up?

It would be helpful if you said that you are northern or southern hemisphere

I feel you man . I got these idiots across the street with a really bright porch light. It's a nuisance. I like to sit out on my porch at night with no lights on and enjoy the night . Now that they have put that light on it's really annoying. I'm about to put up porch blinds to block it out . I'm also going to do what you're doing for the yard. Either my neighbors have no consideration for other people or they are just paranoid and below average Intelligence. I can't stand them

How do I change the scale of size and maybe also the color of the comets? Thanks!!!

Thanking you ... sir ❤❤❤

1:29 - Why is East in California?

Thanks

Bet ya didn't wanna pay all that money for those 8 inch tube rings lol. Don't feel bad, I don't either. I just bought a new 8 inch Meade and I went online to look for a set and almost had a heart attack when I saw the prices that these companies are trying to charge for them. Most are $200+up. Talk about Corporate Greed. Thanks for the strap idea though, that's not a bad idea

This in the guidelines playlist of my uni's astro club

Amazing, and on point explanation, really easy to understand for a beginner like me. Thank you!

You need a video on what you put the deforked telescope on

When you filmed this, did you ever imagine you'd be helping brand new astronomers 12 years later? Just got my first telescope, your videos are so amazing. So much practical advice crammed into these intro videos. Going through your "what to see in X season" playlists too. Pure gold. You rock, man.

What do you think of a zoom eye peice in the astroscan and your got a choice with one eye peice.

New Moon last night and super clear but I couldn't find it after looking for an hour :( I passed over and not realized 8" dob

Sadly, Orion closed their store and laid everyone off.

Great vid! Curious if they are still begun made? (As this vid is 11 years old now) I wish I had found this sooner. I would love to find the accessories for it! I love using mine!

Those have spherical mirror, spherical abberation is more offensive than coma

*BATTERY Q FLASHBACKS* 💀💀💀

Wondering which side of magnetic north you move 4 degrees, the left or right ?

Is it true Orion is going out of business?

This series is really cool, exploring objects while pointing out things about light pollution. I guess I now have something to binge watch the video series while my photos are stacking :)

How about a vid on drift alignment?

It past 2022!

One of easy,s one tks

overall it's one of the objects where it's more interesting to know whan you're looking at than just the apearance of the object it's self something an armature astronomer probably should do with most of their targets

But people who spend 2-3k on an OTA spend 3-10k on a mount all the time :)

Since the expanse 6 and 9 use built in barlow lenses like the premium eyepieces, they also happen to work well in fast scopes. The 15 and 20mm are just like other budget wide fields and will suffer greatly at the edges in fast scopes. I started with 2 slow scopes, an 80mmf11 refractor goto, and then a 127mak on the skyview pro dual axis drive package, since my plan was to later add an 8" newtonian and use it on that mount with the 80mm refractor piggybacked as a manual guide scope, and do film astrophotography as a DSLR was out of my budget, and since they were relatively new, cheap used ones werent plentiful like they are now. Of course being heavily influenced and informed by the orion catalog, i was planning on an orion 8"f5 ota that was what also came on the SVP mount, it didnt come with rings, dovetail, finder or eyepieces, so I went with a hardin star-hoc 8-4 which came with rings, eyepieces and finder for the same, or slightly less money (it was 20 years ago, i forgot exactly but it was about $300). I figured the f4 ratio would be beneficial on that class of mount, being faster requiring shorter exposures than f5, and the added benefits of shorter focal length and a shorter tube length were appealing as well. What killed me was how poorly a the.cheap meade 18mm WA and the more expensive meade 13.8mm SWA (japan series 4000) performed at f4. The 18 was like a whirlpool effect, and the 13.8 was just very astigmatic in the outer 1/2 of the field, but cleaned up great with a barlow. Both were excellent at f11 and f12 in my other scopes. So I started buying older.nagler and UWA eyepieces, since they are a must at f4 if you want to use most or all of the field at 82-84 degrees. But the expanse 6/9, and the stratus/hyperion from 3.5-21mm as well as the planetary 58deg eyepieces based off of the tmb/burgess planetary, and all of those other long eye relief and flat field designs, offer acceptable performance in the more moderate 58-68deg range. This was before prices on celestron, meade and later explore scientific 82deg had come down to 100 bucks in the 1.25 sizes. Explore cut off meade and celestron, and went exclusive on the 68 and 82, and then doubled the price. Tip, used meade series5000 SWA is the same as es68, and the original lineup of 5000 UWA is the same as es82. Celestron axiom LX was also the same as es82

Too bad those prices have gone up quite a bit, 100-200 more than they were prior to the shortages during covid

Refork, or better yet get some money back by selling to somone on a budget with an 8" meade tube. If I ever defork my 10, im definitely going to try to sell the forks wedge tripod, and original giant trunk case as a package

Looks like an old 70s celestron tripod under that wedge

Didn't age well, they are much closer to $300 now

Putting the barlow before the diagonal actually makes it more like a 3x. Not a good way to show beginners how to use a barlow

TFOV stands for true field of view

H and R are not good with fast telescooes, nor are kellners

H20mm is not an eyepiece, it is a dustcap

Remember folks, more light = more crime. In my neighborhood, everything is extremely dark. If you're going to be a prowler, or a burglar, you better bring a flashlight. Having any light source leave your own property is no different than cranking up rap music on a large outdoor speaker. Keep YOUR light on YOUR property. It's very easy to know if you are doing things right. The light source should only be visible from your property. Once off of your property, only reflected light is acceptable.

Mira means wonderful star like Jesus son wonderful counceller

There's no real need to level an EQ mount although it's still good practice to do so.

Been awhile seeing a new video from you David. Wishing you well as always wherever you are.

Could you use the iPhone compass?

Thanks! Wife and me made one for my 6" dobsonian and it works great!!

How do I actually aim the telescope?

Just bought a Celestron model with a wrap of the Moon on it. Really cool looking. Will use it with some higher end oculars. Just for the Moon.

Two of the brightest stars known in the Milky Way are in Cepheus, Mu Cephei and VV Cephei. Both are Supergiant red stars and Mu Cephei would reach to Jupiter's orbit. VV Cephei would reach beyond Jupiter. VV Cephei is about halfway between NGC 7160 and Xi Cephei. As Red Supergiants they are of course variable and if either one was as close as Betelgeuse they would far outshine it. VV Cephei is approx. 5,000 ly and Mu Cephei is 940 parsecs* or 3,064 ly and Betelgeuse is 600-700 ly from the Sun. The 2nd link below has a photo of Mu Cephei and an outdated chart showing relative stellar objects sizes. In the IC 1396 Nebula next to Mu Cephei and next to the Elephant Trunk Nebula is HD 206267 a quintuple star, but only 4 are visible, it is the brightest star in the Nebula at 5.7 magnitude you'd need dark skies to see it without magnification, but a decent size scope can make out the multiple stars except one, you'd need at least a six inch scope to see it at 13.3 magnitude. Alfirk the right corner of the roof of Cepheus is also a visual double star, it's actually a triple star, but one is too close to Alfirk to see in what is called a spectroscopic binary. Spectroscopic binary stars are quite common and they're called that because it often takes a spectroscope to pick them up and/or an observatory class telescope to see them. I enjoy studying double/multiple stars and my back porch faces North by Northwest so I often look at the circumpolar constellations like Cepheus in the evening when I don't want to go out to my son's house or out to Bortle two dark skies about 30 minutes out of town. *A parsec is 3.26 light years. en.wikipedia.org/wiki/Parsec en.wikipedia.org/wiki/Mu_Cephei

According to some authors, Meade's ACF telescopes are long-lasting, but the electronics in the base are not: they wear out faster--and likewise for Celestron. For that reason, I like the idea of mounting a 10-12 inch Meade ACF on an equatorial mount that I use with different OTAs. My Meade 8 inch LX2 was an excellent introduction to deep sky observing, so I am inclined to go further with a larger and more recent version. Thanks for the video and I hope you adopt Buy Me a Coffee and/or Patreon.

Thank you so much for the video! What program did you use to record Stellarium while you speak? Thanks a lot

Just start calling it by the original name Ur-ann. Anus obviously doesn't work.

I saw this star outside today walking inside my apartment. Sometimes you gotta just look around and appreciate the things that are out in this world and universe. It’s astonishing. That star is extremely bright and flairs every second it sticks out from every other star. Idontknow for sure what we are living in but it sure is beautiful

I didn't think about the fact that you could line up the telescope with the shadow on the ground. My brain wasn't thinking three-dimensionally. Thank you.
