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.

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 passive tools are tried-and-true.

I went to my local hardware and got these socket-head bolts...

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?
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?
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.
