Collimation App?
I see all sorts of mounts to adapt a cell phone camera for astrophotography. Is there an app that also lets you use it for collimation? Seems like being able to sit comfortably and watch the screen while turning the adjustment screws would make the process pretty easy. Already checked the Android store with no luck.
Any metaphor will tear if stretched over too much reality.

Re: Collimation App?
Why not just defocus the star take a series of snaps and adjust the doughnut. Sounds easy but the star moves as you adjust the mirror tilt
But it can be done.

Re: Collimation App?
A laser collimator with the return crosshair target does pretty well ,What telescope are you using ?
I never have any much luck with software,ccd inspector and sharp cap are suppose to have collimation tools

Re: Collimation App?
Well my though was that you could have a right angle eyepiece oriented toward the rear of the scope, add the phone cradle, and that would give you a nice big picture to look at while you fiddle with those :flame: little screws.
I'm looking at a couple of collimation tools now but have not made the purchase. So the Newt's are getting dusty while the 'fracs are doing all the work.
I looked up this laser tool and it does look interesting. Might reduce my frustration level a tad.

Re: Collimation App?
FWIW, if you are looking to buy a piece of hardware, I've had a laser collimator for about a year -- never felt like I got consistent, good collimation. Bought a Cheshire about a month ago and feel like I get better, more consistent collimation with it. I would probably recommend the cheshire collimator over the laser collimator, since they tend to be similarly priced.
As far as turning it into anapp , you would just need to figure out how to get your camera to look down through that tiny hole in the Cheshire in a way that you can see the image from the mirror end of the telescope.

You may also want to get a set of Bob's knobs. These replace your nasty little allen screws that adjust your secondary mirror. No risk of dropping a tool right onto your primary mirror.

Re: Collimation App?
You don't want that Orion tool. You can get the same, or better even, without the brand-label, and for less...
https://www.ebay.com/itm/SVBONY-1-25-Ne ... 8632!US!-1
I have one of those. It sports a triplet-lens, and for a tighter laser-spot. With the Orion or the Svbony, you will need to check its collimation and correct it before using it to collimate the telescope. Collimating one of those tools will require a jig.
However, I don't use my own for my Newtonians. I use a Cheshire and a collimation-cap instead...

The socket-heads do allow for adjustment with just the fingers, although torquing them down in the end with a hex-key would be required. Still, I've found them to be most effective. Then, anything's better than the original head-less set-screws.

Re: Collimation App?
Ended up getting the next generation laser collimation tool for $24. I'll have to check my box of metric parts to see if I already have replacement screws that size. Otherwise I'll be using my Lowe's discount once again.
I also joined a nearby amateur astronomy club. They are having a telescope clinic next month so if I have too much trouble I can drag my gear to the meeting and get some hands on experience.

Re: Collimation App?
Just got back from the Tri State Astronomers http://www.tristateastronomers.org/ Telescope Clinic. First time I've met with them, super bunch of people.
They showed me how to use my collimation tool on one scope, and watched while I did the second one myself. Got other tips and learned about some local shops that carry gear.
