Help needed with focus/collimation

Recommended Posts

Hi guys, I have just collimated my scope and everything is lined up fine. The problem I have is this.

When I look through the eye piece. I am unable to get good focus any more.

I also need to look right in the centre of the eye piece in order to see anything, If i move my head at all, part of the image is getting cut.

Any info to assist would be magic.

My scope is identical to this one.

Thanks

the fact you say you cant get focus surgets your collimation is as good as you think. as for the latter sounds like kidney beaning, some eyepiece dont suit some peoples eyes, my mate has a 32mm panaveiw he swears by yet i get bad kidney beaning when i look through it

I'm assuming here your scope has given decent views in the past.

When collimating, what adjustments did you make?

Yes the views were not bad before but the mirrors were really dirty and have been removed and cleaned. a few scratches on both (not me)

not sure if the focus tube is out of line and that may be part of the problem. the spider is centred but i can not get a centred focus in sharpcap the image is to one side

even then the secondary is pretty central to the focus tube.

Here is a picture taken with sharpcap. As you can see the image is off centre. although collimation is pretty good.

Hope this helps understand my problem.

Thanks
