Thanks for an excellent presentation of our instrument Stewart. It
really nails how easy it is to use and the excellent result it gives.
There has been questions to if the instrument can be attached to
different sizes of adapters. Yes it can with additional adapters that
inserts into the instrument with different end size. We will offer
standard sizes like M68 and custom size. Our order site will be extended
with adapter selections. I assume that the cost for one adapter will be
approx. 25$.
Thanks Erik. 👍🏻
Great. Will be checking your site so I can order the adapter as well (M68). Thanks.
~$250 to fine tune $10K worth of astro gear is so worth it. Thanks for showing what it does and how it works, I would have never found it otherwise.
Thanks for the comment, much appreciated..and so true, we pay a lot in this hobby, for very small things, so it’s not expensive in the grand scheme of things..👍🏻
Great presentation! They’ve just sold one of these thanks to you!
Thanks very much, for the comment, truly appreciated, it’s a wonderful piece of engineering, and you will be happy with your purchase 👍🏻
Thanks for buying, Erik
Great video Stewart. Very useful device as chasing tilt can otherwise be a real pain. Clever little device. Clear skies
Thanks Logan, yes it’s an excellent little device and so simple to use 👍🏻
Excellent tutorial Stuart! A really useful tool. Looks relatively easy to use! Thanks for sharing 👍 CS
Cheers Simon, much appreciated, it is very easy and quick to use, it must be if I can do it..😂 clear skies mate 👍🏻
Thanks!
Thanks very much Erik, much appreciated 👍🏻
Another faultless vid Stew, nice one (Y) keep up the great work.
Thanks bud, much appreciated…👍🏻
Genius
Thanks for the comment, and yes I totally agree..👍🏻
brilliant!
Thanks for the comment, yes I think so too, it’s an excellent piece of kit..👍🏻
Thank you.
Cheers my friend..👍🏻
What a great bit of kit Stewart I've always held off adjusting tilt as it seems just such a faff unless of course you make up some sort of jig like you did in your earlier video, as far as I'm aware I've never come across much tilt when using the refractors but oh boy when I use the RASA 11 that's a whole different story so getting it just right is something I need to sort out especially when using the APSC sensor on my Altair 26C camera as that did show up some tilt. The only issue is finding a tilt adapter that's low profile as with the filter drawer & rotator already in situ I haven't got much left on my imaging train so I'll have to look into that. Other than that I'm definitely interested in this product, clear skies!!!!!
Thanks Tich, nice to hear from you hope the recovery is all good with you. Yea it’s a great bit of kit, very useful and simple to use indeed..
Clear skies bud 👍🏻
Yup I'm recovering nicely now glad all that hospital stuff is behind me, maybe I'll finally get out under the stars sometime soon hopefully.
That's an interesting piece of kit. I'd really like to see it have an M48 male threaded adapter, because as is it won't work with my imaging train. I have a Poseidon-M bolted to a Phoenix filter wheel, which is bolted to the OAG. That is 55mm and threads directly onto my 15028HNT, a fast f/2.8 newt. Most setups with a 55mm back focus requirement using an OAG are the same way - the OAG threads onto the scope directly. Believe me, I'd love a way to address the tilt of that setup other than the tedium of NINA's aberration inspector, CCDI and ASTAP analysis.
It looks like you're just sliding the device onto an extension ring, and it is resting against your tilt adjuster. The end ring of the device as well as the plate of the tilt adjuster it's resting against would have to be flat and level down to the micron, otherwise the device itself is introducing tilt. Further, the laser, prism and sensor all have to be precisely angled, or they, too would be introducing their own tilt.
Thanks for the comment, first of all why can’t you get an 55mm to M48 adapter, then an M48 tube ?
As for everything being perfectly flat, it does not matter, as long as it’s not altering during the rotation of the device and the test, the device could be tilted slightly, but as long s it stays on the same plane throughout the test, then all good.. 👍🏻
@@Astro_Shed why can't I get an adapter? Because that would not be part of my imaging train. I have plenty of extension tubes around and could easily thread an M48 one onto the OAG. However, in doing so, I'm adding a component that could itself be introducing tilt. So, I adjust the tilt using the device, then unscrew my M48 adapter, thread the camera/wheel/OAG back onto my scope and I'm tilted again.
As for the device and the laser/prism, does that need to be collimated (for lack of a better term)? For example, I have a Hotech collimating laser. The laser needs to be collimated, so when I rotate it around its axis, it isn't making a circle. Wouldn't the same apply here?
Don't get me wrong, I think the device is a brilliant tool and I've been fighting tilt with my 15028HNT for a few years. I'm asking these questions because I've got an f/2.8 system. The smallest amount of tilt becomes noticeable very quickly due to how narrow the CFZ is :). If this device could address that tilt? Then I could spend my nights imaging with that scope instead of trying to solve tilt problems, or being utterly disappointed by the results and tossing the data.
@@JonnyBravo0311 the adapter would only be there to hold the device in position, the device would be flat against the OAG, so it can’t introduce tilt.
As for collimating the device, it’s hard to explain, but no, it does not matter as long as the laser beam stays coming out at the same point throughout the test, then all good, it makes no odds if it’s coming out at a 45 degree angle, to the device, as as long as it hits the sensor of the camera and stays at that same angle throughout the test, then all good, it’s hard to explain via text, but the laser can be coming from any angle, it does not have to be directly parallel to the sensor, but it must remain at the same angle while testing.
@@JonnyBravo0311 Look at the top comment from me Erik, we can deliver adapters that fits into out instrument that can have both standard and custom size that will fit your attachment a. We have made prototypes that seems to be ok.
So will this work with my filter wheel attached (through the Luminance filter)?
@@j.s.3407 thanks for the comment, absolutely yes, I had my filter wheel on in the video, and should be fine with an L filter 👍
this is genius
Thanks for the comment, yes I totally agree 👍🏻
Nice work stu
Thanks very much..👍🏻
Very nice device! Does it also support tilters with four screws rather than only three? My PlayerOne Artemis-M has four.
Thanks for the comment, yes you have the option to choose in the profile, if 4 screws than you would make 4 sample points..👍🏻

That looks like a fantastic product! I'm curious though, what if you have a larger reducer/flattener like the E.S. 3" 0.7x?
Also, since the vendor is here... Your website doesn't look right on Windows using Chrome in dark mode. Most of the text is unreadable.
Thanks for the comment, so if you have a 0.7x reducer, then in the profile you would put 0.7 in the relevant box, it does not matter what size the reducer is, the reducing factor is the only metric it needs, and that is just to work out the critical focus zones, you can still adjust for tilt regardless.
I will let them know about the website issues, thanks 👍🏻
Looks fine with dark theme on Google chrome on my PC and on my iPad Pro.
Hi I am Erik one from Astro Precision, we will offer adapters to both standard and custom sizes. I will present on hopefully tomorrow which I will use on my Esprit 150 0.77 reducer which is 74mm.
Hi, adapters can now be ordered at out website
nice
@@CDigata thanks for the comment, much appreciated 👍
Hi Stewart! That is really cool. Nice demo. Does the software support a camera with 4 tilt adjustment points? I’d like to get in touch with them to see how it does on my style camera tilt plate.
Cheers!
Doug
Hi Doug, thanks for the comment, yes mate you can choose 3 or 4 point tilt adjuster in the profile settings page 👍🏻
Nice. How precise is the fit between the TiltPrecision and the imaging train? If there is any slop, won't that impact tilt measurements as you rotate?
Thanks for the comment, probably best to watch all of the video to see how accurate it is, as I show that, and I also show how well it fits, I adjusted my tilt in the video down to 4 microns very easily, so pretty accurate. 👍🏻
It does not matter what you do when you rotate, it only matters when you take the sample point.
Then I imagine it will also depend on how flat the end of the tube of the TiltPrecision is as well. Hmm trying to think about this. But still very interested.
@@edwyun1004 actually no, that makes not difference at all, the angle of the laser does not matter at all as long as it does not change during the test, it really is that simple. It’s just looking at the reflected dot, so even if the laser was coming in from a 45 degree angle it would still be fine, as long as that angle does not change during the test.
Interesting! I’m guessing software is Windows only?
Thanks for the comment, hmm, yes as far as I know, but maybe ask the developers, all I know is it started from a simple python script 👍🏻
I am interested in getting one. Is this device only looking to remove tilt caused by mechanical devices being machined slightly out of true, I am concerned that it will miss tilt caused by sag in the imaging train. For you it was ideal as the tilt was not load dependent but by your sensor. In my case I have and ASI2600MM, 2" filter wheel, off axis guider, tilt adjuster, M54 to M48 adapter, Takahashi SKY 90 that connects to my Takahashi QB 0.73 reducer and that attaches to my Primalucelab Esatto focusser. The reducer does have a 64mm unthreaded nose that normally slides inside the focusser. Would I order an adapter that would fit over the 64mm nose? If I were to guess I would say that half the cases of tilt would come from the focusser itself (which is why I replaced my stock focusser).
Thanks for the comment.
Yes this device is for your complete imaging train off the telescope, so if you get rid of my tilt from your train, and then you still have tilt, when imaging then you know for sure it’s coming from your focuser, as you have the essato I doubt that will introduce any tilt, but I may be wrong. If it is coming from the focuser it’s a difficult one as the tilt will move when imaging in different parts of the sky, due to weight shift, so if you adjust it out in one position, it can be worse in another. 🤔
adapters can be ordered from them see link in description, I think they will make them to order, but check with them.
Hope that helps 👍🏻
Adapters can now be ordered at our website
Interesting device, but is using a 3d printed plastic nosepiece connection solid enough for this kind of measuring ??
Because the device slips over the M48 adapter, that alone can cause some tilt, it would be better to make a solid connection with a m48 rotator for example
Thanks for the comment, I thought that too at first, but it’s pretty darn solid when it’s fully over a 2” Nosepiece, there will always be some movement as we are dealing in single figure microns, but to be able to adjust to within 5 microns is excellent in my opinion, the secret is to make it a pretty tight fit, if too loose then that could cause issues, I used an M48 extension tube rather than an M48 nosepiece, as the extension tubes seem to be a bit thicker. Hope that helps..👍🏻
Who makes this and do they have a website?
Thanks for the comment, all the information is in the video and links in the description 👍🏻
Where does the tilt come from. You have me puzzled as to why you adjust tilt.
Thanks for the comment, tilt can come from anywhere in the imaging train, which means the camera sensor is not parallel to the incoming light from the telescope, and so can produce poor shaped stars in the image, the tilt on my set up is from the sensor not being fitted into the camera perfectly level, which is more and more common nowadays, and is from poor manufacturing and bad QC. This is what having a tilt adjuster in your imaging train is a must and why they are sold now.
You are actually adjusting the tilt out of the system.
@@Astro_Shed thanks for the reply. I had never heard of tilt. I have an Altair Astro hypercam 269 c pro tec on an AA 115 mm refractor. I have never seen any indication of a problem. Fingers crossed I never do.
@@steveg4iwr Add a filterwheel, OAG, flattener and then put it on a system like a fast newtonian and you will get to know tilt all too well. 😆
@ sounds like a combination to avoid lol.
