eq3-2 and guiding

[theghettostylus]

Hello everyone!!

I have an eq3-2 mount with the RA/Dec motor drive (none stepper) and was wondering if there is a mod to allow for auto guided imaging?

I've seen someone's post on here about it before but wanted it explained in layman terms as I'm still very new to astronomy and imaging. At the moment I can get up to about 50 second exposure with my rough polar alignment and would like to extend it to a couple of minutes maybe.

Thanks!

Something like this might be what you're after.

Worth checking with the retailer or your preferred astro-supplier before you spalsh the cash tho.

Was thinking more along the lines of guide scopes and modding my hand control to be able to run it through a computer along with the guide scope.

But thanks anyway dont really want to go with synscan and their rip off prices aha

Dependent on the type of hand controller you've got, but there are plenty of sites on-line that detail modifications that add an ST4 port to the hand controller. Then you can use a computer to drive the mount using PHD2 etc....

Can I use a nodded webcam for the guide camera or would I have to buy one?

This is the modification kit you need to convert the standard DA handset http://www.opticstar.com/Run/Astronomy/Astro-Accessories-Imagers-Shoestring.asp?p=0_10_5_0_5_5 and instructions  http://www.opticstar.com/download/Astro/Doc/imagers/Shoestring/eq_mod.pdf . You will also need an autoguider interface to connect the handset to your laptop, or a standalone guide camera http://www.firstlightoptics.com/guide-cameras/skywatcher-synguider-autoguider.html

A modified webcam will require an auto guide interface whilst a dedicated guide camera plugs into the laptop and ST4 port on the handset.
