I collimated the scope last night but it might not be clear for a while so cant do a star test. Visually through the focuser it looks very good.
Any hints and tips greatly appreciated!!
Thanks

Now Tom, since you have a howie, do you have any of the addons for it? My retailer sells howies but with no addons, they do have a Barlow for it, woundering if it's worth getting a howie and finding the ring holographic addon overseas so I can use it to collimated my focuser onto the secondary of myUlteriorModem wrote: ↑Tue Oct 15, 2019 3:13 pm I collimate mine with a Howie Glatter laser focuser in the eyepiece holder. I look down the objective to where I can see the 'return' dot and center it with the secondary first then fine tune the main mirror.
But by far the best 'tool' is a star test. It might take a little guess work at first but a good star test and adjustment is the most accurate way.
You might even consider getting an artificial star. I have one but have a problem with not being able to get it far enough away from the scope to use it.
Here is a series of videos that may or may not help.
