I still have my "Astroscan 2001" that I purchased for (if I remember correctly) $199 circa 1976, with the Edmund Scientific Company RKE 28 mm eyepiece. Great engineering, wonderful product. I'm going out tonight with it to see if I can still find that comet. It's been so long since I've done stargazing that when I took the eyepiece apart today to clean the optics I couldn't remember which direction to put the lenses back in, but when I called the Edmund engineering support line the tech guy quickly sent me a cross-sectional diagram showing how the lenses should be positioned within the eyepiece. Best customer service experience I’ve had in a long time, and this for a product made nearly 50 years ago! I see someone commented that one drawback is you can’t clean the inside of the Asctoscan. I recall that when it was about 30 years old the objective mirror looked a bit spotty and was very dirty, and the collimation seemed off, so Edmund told me to mail it in. They re-“silvered” (aluminized?) The objective mirror and collimated it, and sent it back - for free. Or so I thought. But after watching this buyers/collectors guide video and seeing that details of mine match what the video calls the “later models,” I think what they did was just replaced the old one and sent me an entirely new scope! They probably can’t do that for free anymore these days, just because of the way things are now in general, but who knows.

7:45 - I bought one of those self-stick flexible measuring "tapes" they sell at Lowe's-Depot-Menards to stick to the edge of your table saw, and stuck it on the counterweight tube of my Star Adventurer GTi. Et Voila! Now I can easily repeat my counterweight placement every time I take the rig out for a session. Beware, though: Some measuring tape stickers are not as thin as others, and depending on your mount's weight clearances you may need a *REAL THIN* sticker to let the weights slide on the tube without jamming up. Just a thought; worked for me. Thanks for the good solar tutorial, HTH, HAND, &c...

Seems redundant certainly. These things we’re selling like wild fire several years back unfortunately. There’s nothing more sad than someone getting duped into buying a telescope just for it to end up in a closet or yard-sale. Lots of potential astronomers lost to such garbage. Not everyone knows what to expect. You’re absolutely correct tho. I’d love to know how much the labor cost was in fact.

Initially yes but as your batteries approach depletion you’ll notice a lot of variation. Converting to AC also comes with issues. Irregular voltage seems to drive it off course. You absolutely have to check an alignment star and make corrections over time unfortunately

On a static tripod use the 500 rule and take some test photos. Look for chromatic aberrations and pay attention to how pinpoint you can make starlight. I’d use a UV filter if you have one.

Excellent video Garnett. Just a heads up (others have probably already said this in the comments) - the larger blocking filter means visual observing with an eyepiece will be more comfortable, especially if you wear glasses. Also, vignetting will be less of an issue with imaging. The larger blocking filter also gives you more room around the solar disc for proms...

Managed to eliminate most of image shift following your video!. Mirror is a solid piece of glass, not as delicate as what most people think. I put a “cover” on the mirror with soft material so I could work freely when doing the adjustment w/o any risk of damaging the mirror. My only mistake was not to properly clean the protective surface and I had to clean the mirror afterwards…not a big deal with alcohol and cotton.

Any tips on focussing? I really struggle to get a sharp image and any help would be much appreciated.
@GarnettLeary6 ай бұрын
That’s where most people struggle. Two of the easiest targets to acquire proper focus on are the termination line of the Moon and very bright stars such as Vega and Sirius. With the Moon it’s obvious where the sharpest point of focus is. Stars are a little more tricky but you want them as small as possible. Typically an optic will arrive at perfect focus on the inner or outer side more than the other. What I mean is the spot past perfect focus wether it’s going out or in towards it. Every scope and lens I’ve ever used seem to arrive sharp from one side or the other easier. You know how you’re there fiddling with it and it seems right until you take your hand off? If you can’t get to that sweet spot it could be in some cases that the focuser is too sensitive. If it’s a knob, like a Maksutov has, often people will attach a clothes pin or something similar to create a reduction or fine focus. Ultimately the easiest work around is a Batinov mask. So many people have 3D printers now so getting one cheap off Etsy is easy. With a Batinov mask there’s zero doubt that your focus is spot on. Just remember that most all optics will go out of focus under temperature changes. If you setup and say the temperature falls five degrees then you definitely need to check it again. I spent the better part of 15 years manually focusing. It’s something that remains difficult no matter what and ultimately nothing beats a good Batinov mask along side a star test.

I'm picking one of these up now. For $30 or $40 it seems like a great choice to take hiking or camping. Use a 1.25 upright diagonal and it's a spotting scope; a regular diagonal and eyepiece and it's a cheap 80-90mm telescope. Way cheaper than a C90; hopefully lightweight too. The one thing missing is a tripod collar, but you get what you pay for :-) If I wanted one, I'd go for a used Sigma or Nikon... or just get a C90.

I have a Celestron 80mm (f/5) refractor. I have found that a SvBony CLS light pollution filter eliminates all chromatic aberration by blocking the color blue entirely and it is cheap. I have also found that using narrow dual band filter eliminates all chromatic aberration and allows you to photograph on nights with a full moon, but only allows you to photograph emission nebulae.

@GarnettLeary7 ай бұрын
I think this scopes strengths exist more in its portability. Aperture is king in planetary and that’s where it falls short. This is a great scope for someone that likes to hike, camp, and travel. I feel like the focal length is a good all around number but that it may not be as suitable for someone not concerned with being on the go. If you’re trying to stay in this price range, and can give up portability, I’d recommend a Dobsonian 100% of the time. You’ll get way more speed and aperture which is more beneficial for photography and discerning details visually. In short, this product will exceed the purchase price but will be limited in it’s ability to see faint details because of its small aperture. As a generally accepted rule of thumb an 8” aperture is the go to for entry level planetary. That being said I’d place this scope at the top tier list for its aperture and price group. If you could toss a number up of roughly your maximum investment I would be glad to give you my recommendation. Most people will ask you the same thing. The first question is how much you want to invest in it. The second is what you aim to do with it, or expect out of it. Would be glad to advise. Clear skies.

You can also use the shadows from the sun. As the sun drifts across the sky the tip of a shadow such as your tripod will make a straight line East and West. Mark one Point and wait 10 minutes and then mark the other point. Draw a straight line between the two points and place two of your tripod legs directly on that line and the third leg will be pointing North or South as long as the legs are equally spaced out. Also, if you setup at Solar Noon the shadow will pointing directly north as well in the northern hemisphere.
