Quote:I use a hand truck to move my AD10. Would I still be able to do that with the HALO installed? I can't tell if it extends down past the ground board enough to cause a problem with the hand truck blade getting under it. Probably not, but I will pose the question anyways.
Quote:Very nice product indeed! I was hoping someone would come out with a product like this with leveling feet.Someone should also come out with a dob mat degree circle with a beam of laser as pointer. Just a thought....

Quote:Price for a z10? I can't find it on your website.
Quote:David,I am the happy owner of a new AD12. If I may make a suggestion. You know those casters you can get at hardware stores that have three wheels and a nice little well in the center? If the wheels on those were locking, then you could offer them as another option for your Halo. There would be no redesign of the halo and then folks wanting the option to wheel their scopes out could simply set the feet into the casters and the levelers would still work. The Halo, while really cool, would not appeal to me personally, since I prefer to keep my AD12 on wheels. But, if it had the option to use wheels, it would be a leveling base, setting circle and scope dolly all rolled into one. Also, do you plan to sell angle finders for alt? If you could source something like the Wixey, but with a red backlight, many of us would buy it.
Quote: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.
Quote:this is a very specialized, practically a handmade product, which will keep the quality up!
Quote:Maybe CNC from a plastic material that can be recycled? 3d printer? Other production ideas anyone?
Quote:How do these DCircles work?
Quote:Another nice thing about these separate outboard degree circles is that both the degree circle base and the setting needle can be oriented almost anywhere depending on which side of the ota your eye piece is located, for instance. Some people even find having the setting needle at the front of the scope (under the belly of the scope) more comfortable as well.

Quote:Quote:How do these DCircles work?Basically, they help you find objects in the sky by allowing you to point your scope at the current azimuth of the object you want to observe. You also need a Digital Angle gauge like the Wixey (sold separately) to point your scope at the current altitude of the object you wish to observe.And to get the current Altitude and Azimuth of objects you want to observe, you can use an application on your phone, iPad, laptop computer, etc. Popular apps are SkySafari (my fav), Starwalk, and Stellarium.So, for example, if you're observing shortly before dawn in central Alabama, and if you look up the Orion Nebula (M42) in your app/computer program, it might show that M42 is currently (at the time you're observing) at an Azimuth of 193° and an altitude of 48°. You would simply rotate the scope until the HALO's pointer is pointing to 193°, then raise your scope's tube until the Wixey reads 48°. At that point, your scope should be pointed at the Orion Nebula and you should find it in the field of view of a low power/wide angle eyepiece.Let me know if that helps you understand the basic concept, or if you want more detailed info.David GilesOpticsmart.com
Quote:How does one ensure the scale is exactly concentric with the axis of rotation?
Quote:Thank you for clearing it out.
Quote:David; I'd like to see some sort of a red light on the pointer, to avoid using a light everytime one moves the base, that would be a great addition.
Quote:that if we DO offer a custom lighting solution for the HALO at some point, it will be an optional add-on.
Quote:David; nice idea! There's so many red lights avail, that I'm sure something will work for buyers. Quote:that if we DO offer a custom lighting solution for the HALO at some point, it will be an optional add-on. Absolutely! This is the best way to go!

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. I'm glad you like the HALO aznights, and thanks for spreading the word about it to your friends and colleagues! And I can understand wishing that the HALO was less expensive. I wish EVERYTHING I wanted to buy was less expensive. But the HALO isn't a mass produced product that can take advantage of huge economies of scale. All of the materials and parts that make up the HALO must be purchased in relatively small quantities (as compared to say the parts of a wheelbarrow that is made in China and sold by the millions in every Lowe's, Home Depot, and WalMart in America). And the HALO rings are CNC-machined out of 1-1/4" thick Extira (which isn't inexpensive, and because of the ring-shaped nature of the product, as you can imagine the material-yield isn't great). Then we have to do some hand-finishing work on the rings because they aren't ready for prime time right off the CNC bed. The degree circle inlays are also custom-made for us to perfectly fit the CNC'd Extira, and the leveling feet were special ordered as well. After finishing the Extira, we have to properly assemble everything and get it ready to ship.CNC-machining certainly isn't the least expensive way to produce a mass-produced product, and the truth is that if we thought we could sell TENS of thousands of HALOs in a reasonably short period of time, those quantities MIGHT justify investing in injection molds and manufacturing the rings out of plastic. With the cheap cost of raw material, and with the mold costs amortized over tens of thousands of HALOs, we could probably offer them at a significantly lower price. But injection molds are incredibly expensive, and we would need to invest in FOUR different molds just to cover the GSO-made 8", 10", 12" and 16" bases. Then we'd need several more molds to fit the different Orion bases.But even if I was 100% confident that we could recover the huge investment in injection molds in just 2-3 years, I still wouldn't go that route, because then if the Asian OEM base-makers changed the diameter of their Dob bases by just a little bit, our huge investment in molds would become instantly worthless. Instead, with CNC-machining, we can change the HALO dimensions to fit any change in bases with just a few keystrokes in Solidworks (the 3D CAD program used to design the HALOs).So yes, you are paying more for the HALO, which is a highly customized product available in several sizes for a low volume, niche market, than if it were a one-size-fits-all mass-produced product on the shelf of every WalMart in America.And believe me, I wish everyone in America wanted a HALO. But unless I'm completely wrong about the actual demand for HALOs, I suspect it will remain a very cool, albeit niche product which carries a price tag that is reflective of its production volume and production method, and is not unreasonable (IMHO) when compared to other niche products in this market.And by the way, aside from all the manufacturing issues, keep in mind that the prices do include custom-made shipping boxes as well as the cost of shipping the product to your front door. If you check the costs of purchasing 30"x30"x6" boxes in relatively small quantities from a box-supplier, and THEN check the cost of shipping that size box across the U.S. you'll find that those costs aren't insignificant....David GilesOpticsmart.com
