I bought my Vixen Polarie from OPT in the US, I am sorry to say, several (maybe two ? or more?) months ago, but haven't actually used it till today.
I have seen some discussion regarding this mount on IIS so maybe this report will be of interest
The reason I havent tested the Polaries is mainly because I also have an astrotrac-had that for over a year- and have been still fiddling with that to try and get my workflow optimised.
Obviously I am sucker for small portable mounts that track well and dont need autoguiding
having managed a decent (well I think so) image with the astrotrac a few weeks ago, today I took the Polarie out for a spin,
First power
I used rechargable eveready batteries which I got from Coles. I was expecting 2 hours. I got possibly 3 and a half or possibly four..the mount was stiil going when my camera battery gave up.
secondly tracking
obviously polar alignment is hit and miss. does Sigma Octans actually exist?
still sort of just pointed in the general direction, after finding Sigma Octans with binos. I used an inclinometer to set the latitude though.
I got 30 to 45 seconds without trailing.
I am sure it wont be too hard to push this up to a minute. You need some one to stand next to you with a green laser pointing at the SCP and you can set up in minutes.
Unfortunately tonight I was the only one from our club at the dark site.
So as far as the mount is concerned, I think it tracked exceptionally well despite the rough and ready polar alignment
I stuffed up as usual and didn't image in RAW but captured jpegs.. still trying to figure out how that happened :(
but I imaged for nearly an hour on a couple of targets, and the mount tracked really well.
here is one image-about 55 thirty second image stacked, and a bit of the normall processing in photoshop
overall: am I happy with this purchase?
You bet!
It weighs nothing, works really well, doesn't chew up battery..if I lived in the northern hemisphere and could polar align easily I wouldn't buy another mount !
oh of course it has limitations. It has a load limit-I used the stock canon 18-55 lens which it handled with ease. Big lenses? I don't know. (i don't have any fancy lenses, I use a Borg 45ED with the astrotrac..and I don't think the Polarie is capable of handling even this tiny telescope..got to try one day)
The attached image is with a Canon 550D (stock) with the stock 18-55mm lens. I think this image was at 55 mm at f5.6.
:)
Yep I am happy.
I used a tripod I already had, so didnt have to invest big bucks
I know what I am taking to Cairns in November. :);)
