I've been thinking (always dangerous they tell me...)

 

Instead of making a table tripod, has anyone attempted mounting some heavy duty foldable legs directly to the base? Similar to the below but heavy duty...

 

Yes, I hear you now, that's wobbly, too much weight, it may not fit well...

 

Just wondering what y'all thought?

Those legs may not be stable enough but the idea is a great one. I attached legs right to the bottom of mine.  they don't fold but I don't need them to,.This setup has worked very well for me.,and the OneSky.,

I have the tube covered with nice black light-absorbing flockboard. I think it helps. (I do not know about a baffle on the OneSky, I will search this forum for that.) https://www.fpi-prot.../flockboard.htm

 

However, I still cannot find the Ring Nebula. Maybe I need darker skies? I am in the San Francisco Bay area. I tried in San Mateo and in Santa Clara. Places with too much light pollution?

 

Or am I looking in the wrong place in the sky? Sky Safari shows a triangle of Vega at the top, Cygnus lower left, and Vulpecula lower right, with the Ring Nebula slightly below and to the right of Vega. Is that the right spot?

 

I have a nebula filter which works great, but only after I find the nebula in the first place.

 

When the SF Bay area astronomer club was meeting in the hills in San Carlos, I was able to spot the Ring Nebula, with a little help from other star gazers.

 

I will keep trying for the Ring Nebula. And I will look up more stuff per your advice. But it seems that when I look up the best deep sky objects in Sky Safari, the majority are just barely above the horizon.

I looked at the ring nebula the other night from suburban Chicago - probably bortle 8/9 and with haze.  At lower magnification it was barely there - just at the edge of seeing.  Even at higher magnification, there was not enough contrast to see it as a ring.  Probably would have helped to put the UHC filter on it.  The point being that enough light pollution and haze will kill it.  I haven't seen squat from my driveway since they opened up two new car dealers down the road last year.  Lot easier in a dark spot.  You will just have to get back in the hills.

I saw your setup earlier and that inspired me to see if I could find 3 identical crutches, but the thrift shop had 2 pair and they didn't match close enough to satisfy my OCD.

 

Those are crutches aren't they?

It sounds like you may need to refine your search a bit. Look carefully for the Ring Nebula about midway between the stars beta and gamma in Lyra. It will appear small and dim.

 

I used to spot the Ring from Redwood City with the three-inch reflector listed in my signature. That was decades ago, though, and I imagine light pollution has increased since then.

I was able to add two encoders to an AWB OneSky and I now have a wonderfully simple push-to system. See the details in the post here

https://www.cloudyni...ers/?p=11235454, and read the entire message stream for lots of tips and help

 

Don't want to double-post, but I'm quite frankly amazed how well this works, and how simple it is to build. No soldering required

 

Very nice job!

Yes they are,.I had the same problem with the different sizes but didn't notice till I was home.,It was with these aluminum ones and I was able to "fix" the short one.,

(EDIT: I searched the forum, and I think the baffle refers to extending a little light-blocking at the front of the tube. I used a little flockboard to do just that because at a star party at a San Jose school, sometimes light would peep into the eyepiece from street lamps.)

 

However, I still cannot find the Ring Nebula. Maybe I need darker skies? I am in the San Francisco Bay area. I tried in San Mateo and in Santa Clara. Places with too much light pollution?

 

Or am I looking in the wrong place in the sky? Sky Safari shows a triangle of Vega at the top, Cygnus lower left, and Vulpecula lower right, with the Ring Nebula slightly below and to the right of Vega. Is that the right spot?

I can see it in my One Sky and I am a real novice. It is actually one of the easier Messier objects to center in the eyepiece. I have a RACI which helps a lot. There are two bright stars that form the bottom of the parallelogram of Lyra, Sulafat and Sheliak. The nebula is on a line between them, a bit closer to Sheliak. I can easily fit them both in the finder  eyepiece and center the crosshairs on this spot.

San Mateo and Santa Clara might have too much light pollution, they are right there in the thick of things. From here in Almaden Valley the sky toward downtown San Jose looks almost like the fires of hell (except that it's white instead of red). If you could find a location west of 280 and 85 that would help a lot.

 

WillR posted a nice chart of where to look. At low power the nebula looks more like a star, so it has to be more precise than "to the right of Vega". Sheliak and Sulafat are nice references because they have a very unique recognizable pattern of other pretty bright stars next to them, so they are easy to identify. Again, at a low power you'll be using for initial aiming you are not looking for a nebula, you are looking for a star. Once you find it, you'll notice it has a bit of a fuzz to it. That's the time to up the power and add the nebula filter.

I have observed the ring many times and never felt the need for a filter of any kind.,It sticks out quite well as is once you know where to look and what it looks like.,At low power you can see it as an unfocused looking star.,If your scope is focused it is easy to see the fuzzy looking star in the  middle of the two bottom stars in Lyra.,

  I will  say this.,My daughter could see it easy.,her husband couldn't see it at all even after I centered it for him so it could be a matter of the observers eyesight as much as anything else.,

That is the joy of living under dark skies.  Unfortunately, those of us in Bortle 8 or brighter skies have a much harder time and a UHC filter actually does help a bit.  I can still pick out the ring, but ever since they opened up a couple more car dealerships down the street I need the filter if I want to see dumbell.

Light pollution is certainly a huge factor with the Ring, but it also takes practice to observe it.  Our brains fill in visual details that aren't necessarily there.  The Ring looks like a dim star, so our brain sees it as a star in a field of stars.  It's only when we look at each individual object one by one that we see it for what it is.   It's the same principle that causes socks to get lost in the laundry.  We look into the the round drum of the washer or dryer and our brain fills in the details of a round structure, but the sock isn't observed because it isn't an expected part of the pattern.

 

Take your time and look carefully at each bright spot in the field

I hardly believe darker skies are needed to spot M57 (Ring Nebula).

 

Earlier I posted my hometown. It’s Bortle 9 (SQM 17.6 or so). Even I can find M57 quite easily. However, under darker skies, more details are visible (a ring structure instead of a blob.

Thanks to everyone replying and helping me out with my Ring Nebula troubles. (I'll get that wascowy wabbit!)

 

One takeaway is that I am likely to buy a finderscope. I lean toward the Orion 6x30 RACI because I'd want the widest field possible, and fairly low weight. I currently use the supplied red dot finder, and I expect to keep using it. (Advice here is, of course, welcome, but I have posted about finderscopes before.)

 

A sad note that those of you in the SF bay area know: Orion Telescope in Cupertino is closed. I had hoped to buy it there, it was a great store with great geeks running it. Sigh. Guess I'm going online again.

Be sure to buy a new mounting shoe with any finder you are adding. You will need to drill (2) holes in the steel tube in order to mounts this. Be careful doing this to ensure you don’t get any filings on the primary mirror. I suggest masking tape on both sides of the tube, and a new drill bit. You can mount a finder at the mid-point of balance, and it won’t through the tube off.

davstrom - I also live in the Bay Area (south bay), and as you can see in post #5195 in this thread, I've just installed a push-to system on my OneSky. Tell you what - I'll take mine out tonight or tomorrow, weather permitting, and try for the Ring. If I get it, I'd be more than happy to meet you somewhere on the Peninsula or South Bay and we can try together (because, as you know, it took a double-barrel to get the wabbit)

Update on my finder scope decision process.

 

I remembered that I have old 8x21, 8.2 degree field-of-view binoculars. I took them out tonight, and I was able to see lots more stars than with my naked eyes, and get a nice wide field of view. So I think the Orion 6x30, 7 degree FOV finder scope will do the job for me, having twice the light gathering power of the 8x21 and nearly the same field-of-view. And it will be lighter and have a wider field of view than a 9x50.

 

The difference between the Orion 6x30 RACI and the 9x50 is a puny $20. If someone thinks the 9x50 would be worth the extra $20, the extra weight and bulk, and the narrower field-of-view, I'd be happy to hear it.

Interesting, I will be adding a green laser soon. I was thinking about a RACI of some type. We'll see how this works out.

Hello all:

 

I am wondering if a ES Twilight 1 tripod  and it's mount would be appropriate to mount a OneSky on?  I looked around a bit on here and didn't see anything that would make me think it wouldn't, but then again as you can see by my post count I'm a rank beginner. Just got my OneSky less than a month ago :-).  Is there anything about this tripod / mount that would make it a poor candidate to mount a OneSky on?

 

Thank you all in advance!

   The ES Twilight is expensive to use just for the One Sky. You can make a simple wooden tripod, for about $20.00-$30.00. 

AWB 130 complete

You can can get the plans from "eyesonthesky.com". It is a very simple tripod to construct.

Thank you for reminding me about the home grown possibilities for a tripod. I have gathered most of the materials and intend to build one to use around my home and property.

I have also been to a few locations where having a tripod, with independently adjustable legs would be wonderful due to the irregular ground, and that's why I am now interested in a proper tripod and mount. I already own a nice, albeit ancient Leitz Tiltall that I have used with my regular photo camera, but understand that it's not suitable to attach an Alt-Azi mount to.

As a newbie, it's very likely that I have some of this wrong, so please steer me in the right direction if that's the case.

Thank you

.,The T1 wouldn't be good enough for the scope IMHO.,You would find it far to shakey to focus at higher powers and settle time would be long enough for a nap.,build yourself something sturdy and stable and bring some blocks to level up with .,

What Dave said. You can easily level the tripod. I do it all the time.

 

It's easy to get caught up with improving the OneSky. The secret is not to spend a lot of money doing it. Save your money, and enjoy your time under the skies!laugh.gif
