| hello Stevemg
Lookin to take some pictures.
Well if its a single arm GOTO you have , good luck...you are going to need it.
Im not telling you this to bum you out.
You need to get control of the tracking , and with experience with a single arm GOTO ...Exposures for doing Comets, galaxies and nebulae are very, very challenging .
The Best way to take quality shots with a single arm GOTO is to get a wedge and polar align .
This way you are basically using one servo motor...more stable and less streaking of stars. You will notice the stability right away.
Most of the better quality guiding programs are for GEMS(german equatorial mounts) and tie in to a computer and hub and feed back to the auxillary input of the scope for tracking....programs like this a example being ..(maxim DL)
And lets not forget about the cash....ching ching.
You can take your OTA and put it on a good GEM, a good GEM is about 3 000 to 5000 dollars .
I have a CPC 1100 fork mount, its very good for viewing and it does okay for shots , but still no comparison to my buddies GEMS .
IF YOU WANT TAKE SERIOUS PHOTOS GEMS are the WAY...period ... otherwise be happy and settle for what you get.
For imaging using my single arm GOTO I use a program called guidedog ...
It produces a set of cross hairs with a hollow middle and you can click and drag the crosshairs onto a star in a CCD image and manually track and keep the star centered for the duration of the photo...this program is very helpful. and only 20 bucks not 600.
I have and use... 2 different webcams for planetary imaging , a CCD deep sky imager , the Meade deep sky imager is flexible enough to do multiple stuff with , but its monochrome so will require filters, and I also have a Canon Rebel XT , I take the family cam and do use it for Galaxies and nebulae this very good but its a ***** peeking thru the little focuser.
I also have a focal reducer and barlows.
