Does this look collimated to you?

[cuivenion]

First time collimating with a cheshire. What do you reckon? The dark area on the right hand edge is a chip on the secondary.

[cuivenion]

No one? I could do with some help on this as I've not used a cheshire before.

[Nillchill]

doesn't look right to me , you have the cross hairs central, but the whole view seems offset towards the right . check that you're focuser tube is perpendicular in both axis to the tube then recheck it 

cheers

Agree with Nillchill - that dark patch looks a lot like a mirror holder, which would back up the comment about the whole view being offset. May not be the focuser tube, though - could be the secondary is aligned correctly but offset slightly to far down and right in relation to this pic.

Tbh, the image could show one of several things - any chance of a bit more detail if you can get another shot?

[Moonshane]

it's not far out from the looks of things but I cannot tell what is what.

it looks to me like the secondary might want to go up and right a bit which will mean redoing stage 2 and 3. this assumes the bright ring is the end of the Cheshire

[cuivenion]

Yeah the camera on my phone isn't the best. I've started from scratch and done it again I'll try to get some better pics.

Apologies, too down and LEFT, not right.

As per Shane's comments, really (least that means I am doing something right!!!)

Good luck with it and do post back if you are not sure next time.

Take your time, it can be a bit daunting at first and you've identified part of the problem yourself anyway, which always makes finding the solution easier!

You should see the same amount (or none) of each clip around the image.

[ScottS]

That looks alright to me. I think the camera just isn't pointing exactly down the centre of the focuser.

There's a job somewhere here for me?  I wish!.....  Cruising  the UK on my Goldwing, meeting new friends and Collimating Newtonian telescopes, a small fee to cover my costs?

Thing is, I'm not sure there would be any repeat business?  I find the task straightforward and simple, but not everyone does, there lies the deal, but before I leave your residence, you too would be accomplished at collimating your own telescope.

I believe, once you have been shown how, and what to do,  twice at the most, you will wonder what all the fuss was about,  This is where I put myself out of business. There's no justice?

Hi Ya cuivenion, seems to be too much of the shadow "around" the primary(or is that the secondary ?) running from about 10 o'clock to about 5 o'clock I think you need to tweak the main mirror towards the 2 o'clock position and then the shadow will be more concentric - I think anyway - or is it the secondary that needs a tilt ? - great thing about the collimating of an SCT only 1 mirror to move!!

Paul.

For observing, i'd say that it will be ok. If you want to do imaging then it is off by a bit. 

[cuivenion]

Second attempt, 1st to last photo, secondary aligned under focuser, secondary aligned to primary with cap and primary alignment with cheshire. I'm struggling to get a perfect circle under the focuser, is it possible the secondary is slightly misshapen making this more difficult.

[cuivenion]

Thanks for the replies by the way. Paul it is mainly observing at the moment. Been getting into planetary webcam imaging as well.

[jetstream]

Lookin good..... both offsets look very close, once again a pic borrowed from Khadder,Menard- this is the goal.

[cuivenion]

I reckon thats pretty close then, cheers for the help.
