Illuminated reticle crosshair eyepiece suggestions? was created by martinus
Hi guys. My current location doesn't allow me to see the pole star so I'm stuck with setting the mount up using a digital level and a compass. I've had moderate luck in the past with tracking but I really want to get longer exposures.
As such, I've done a lot of reading on drift alignment. A key piece of kit is the eyepiece so I was wondering if any of you could suggest good illuminated, cross-hair reticle eyepieces for the job?
Many thanks.

Wouldn't a good guider solve your problem?I am in a market for one myself and read that you have to do a rough alligment to pole star and the guider does all the work for you.
As at the moment I can only achieve a 3min unguidet shot with my neq6 and that's if I get 100% pole alligment...and it takes quite a while to get it.

From what I've read a guider isn't really aimed at making gross corrections. The point of a guider is to offset some of the periodic error innate to the mount. As such, a guider seems to need a moderately accurate polar alignment to do its job.
Please correct me if I'm mistaken in this, there are a lot of opinions on the matter.

Well i am after the LVI smartguider 2.At least this review sold it to me :
stargazerslounge.com/member-equipment-re...lvi-smartguider.html
The fella claims that he done just rough polar alligment with 1 star alligment and got good results...which will save time, and i read loads more happy stories about this product.The down side is that it costs around 500e new,and that kind of money i do not have.So trying to hunt it down second hand which is a real pain as the product is new....I am hoping that santa will be genorous this year
I presume older generation guiders require good polar alligment but i cant comment on that as i have used one before.

without good polar alignment you will still get image rotation with longer exposures, guided or not.
I use the celestron crosshair 10mm eye-piece. Just a 2 pairs of parellel lines orthoganal to eachother. It serves me very well when I get the chance to set-up around the weather.
Hope that helps some
