I really don't think the HALO would look very classy up on blocks.




I shudder at the thought!

Seriously though, if your floor is flat and level, we could simply send you a HALO without feet, and you could remove the rubber feet from the bottom of your Dob's base. Then just set the HALO flat on the floor, get it oriented perfectly north, set the Dob in it and you're good to go.

Might there be a way she could lock the Halo to the floor so the alignment doesn't drift over time?

She could absolutely do that if she wanted to. If we send the HALO without feet installed, she could simply drill holes in her concrete floor (with the appropriate drill bit) and install concrete anchors at the positions where the leveling feet would normally be on the HALO. Then use long bolts to run through the HALO's leg-holes and into the anchors. Of course when screwing into the concrete anchors she'd have to be careful not to crank down on them TOO hard (as with any MDF/wood product) so as not to damage the HALO.

David, I'm very tempted to just plunk down the credit card! However, I have to hold off for the time being, at least until the funds become available. But I'll tell you, I really want to see this for myself. Despite everything I said, I really like the thinking behind it, and hope to get one sooner than later!

Do the leg holes have tapped metal sleeves that the threaded rods screw into?

Believe me Bob, I understand about funds being unavailable.

We install threaded metal inserts into both sides of the Extira before installing the leveling feet.

Thanks! If you were to leave the inserts in Carol's Halo, could they prevent the concrete anchoring screws from damaging the Halo while at the same time providing a bearing surface for the anchors to be torqued against? Or, would it preferable to leave the inserts out, and just torque the screws against a flat washer?

I would probably recommend leaving the metal threaded inserts out, and using a large flat washer on top of the HALO.

I seriously doubt that the Halo will shift to a point where you had to make constant re-alignment of the pointer. A thin rubber pad or felt paper underneath should prevent it from shifting with all that weight on top. I can understand locking down the mount for EQ mounts, but for setting circles I don't think it's that critical.

I would tend to agree. Just the friction between the concrete and the bottom of the HALO would probably be enough to keep it perfectly still.

Wow, that 10" Orion base board sure looks familiar to me...

The picture of my Halo is awesome!!

Great job,

Please dont get me wrong, I really like this idea, and I'm very excited about this product announcement. I've even shared about this idea on reddit.com/r/astronomy and to some of my colleagues. But I have to be honest, I feel like price on this is a little high.



Well aznights, if you wanna play you gotta pay and it has been my experience in astronomy as well as in everything else you get what you pay for. The Halo is a simple solution to a complex problem. If you do not have the means or the ability to build your own setting circle with leveling and azimuth aligning capabilities it would seem as if Dave's Halo is one very good solution to the common problem of finding and viewing celestial objects.
Of course that is simply my opinion so please take it for what it might be worth...

Thanks for your comments Bill! But just for the record, aznights did go ahead and order the HALO. He's paid, so he can play.

Ahhh....the joys of manufacturing.....

Anyone who has followed this thread closely may remember me saying that I wouldn't dare make the huge investment in injection molds for the HALO because the Asian OEMs could at any time make a very small change to the groundboard diameters and totally ruin our day. Well, that comment was more applicable (and timely) than I ever would have guessed….

Much to our dismay, we’ve recently discovered that in just the past few months GSO made a minor change to the bases that they supply with their scopes. All they did was change the rubber “bumper” that goes around the perimeter of the groundboard to a flatter, less rounded shape. The change is completely inconsequential with respect to the functionality, usability, quality, and durability of the product. BUT, the newer bumper style does reduce the outside diameter of the newer groundboards by approximately .16”, which means that HALOs designed for GSO bases with the older bumper style won’t be a good fit for bases with the newer bumper style.




There are thousands of GSO-made bases out there with the older bumper style, so we will of course continue to stock the current HALO sizes. But we are also working on HALOs for the newer GSO-made bases and will stock them as well. It’ll make inventory a bit more complex (and costly), and we’ll have to communicate well with customers to make SURE they order the appropriately sized HALO for THEIR particular base. But hey, that’s all just part of the fun right?

Hmmmmm, self adhesive shims so you can use one base for both, or a peg that the user can tap in (or leave out) depending on the size of base.

You'd think that something so inconsequential as a rubber bumper would be the last thing you'd change! Then again, maybe their supplier dropped out and they had to go with someone else.

Anyway, I have a couple of questions:

How thick is the shelf that the edge of the groundboard sits on?

How tall are the feet on the end of the leveling screws?

I'm curious about the minimum amount the threaded rods would need to be extended before the feet on my telescope's groundboard start to lift off the floor.

Oops, I gotta remember to check out all the pages on a topic in this forum before I make a post! I hope aznights is as excited regarding the acquisition of a HALO for his Z10 as I am for the HALO for my XT10. And aznights I truly apologize for having spoken out of turn.
…now we both can play.
Clear skies,
Bill

Yeah we've considered shims, but I just don't like the idea of some customers getting perfectly dimensioned HALOs while others have to live with a less optimal workaround. And I suspect that engineering and procuring customized shims that are durable, look good, and REALLY fit well, would probably take more effort/investment than simply making HALOs that are properly dimensioned to begin with.

Yeah I suspect it was a supplier issue.

Approx. 1.5". Or to be more precise:

Unless your Dob's feet are taller than the standard rubber feet that are supplied with most Asian Dobs (which are typically .95"-1" tall), then your Dob's feet WILL be off the floor by at least an inch (at the HALO's minimum height setting). I think this image has the info you're looking for:

Thanks, Dave. Especially for taking the time to enclose those photos. Especially for then doing the math for me! You're easing my worried mind.

What did you use to seal the machined surfaces on the Halo?

We don't apply any sealer. The HALO will withstand far more exposure to moisture un-sealed than your Dob base ever could. As I said you could leave the HALO out in the rain overnight. And eventually I'm sure someone will.
