Baby's first Polarie exposure

After finishing with a wedding tonight, I managed to get home and quickly set up the Polarie for the first time.

I have never used a polar scope before. But, I used the polar meter to point about south with magnetic declination in mind, and, accurately set the inclinometer to 35(.2) degrees.

I slid the polar scope in and by just moving the tripod head a little bit, I thought I saw the trapezium in Octans. Never seen it before! I rotated the polar scope and the stars were pretty much in the spots on the reticle where they should be. Great success!

I couldn't point at Crux as the body of the camera was hitting the Polarie unit. How have people got around this? I think I'll have to buy an extension arm.

Anyway, I saw Scorpius rising above the house, so, pointed at it and took an 8 minute exposure (with in camera noise reduction). Despite the light pollution and the 84.2% Moon.

This is the result. Very, very happy! Apologies for the JPG artifacts. I saved it as a 200 KB image for forum.

Canon EOS 5D Mark III, Canon EF 17-40mm f/4L USM
480 secs f/4.0 @ 40mm iso100

I simply can't wait for dark skies to play with this thing.

Cheers, all.

Mike, the Milky Way is easily visible on nights where there's no Moon or its phase is early/late. I'd imagine my backyard would be half-decent to image from.

I might get to start on a project I've wanted to do for a long time!

Very cool. You'll love it. I have mine running on the side everytime I'm out imaging. Always using it for something.

Yes, I remember when I lived in Karabah in 2003/4 for 9 months while we were building at Mt Cambell in Googong, the skies were quite good, especially to the East and south. I had the 12" LX200GPS setup semi permanently in the back yard and did plenty of imaging, the last two rows of thumbnails HERE were taken from there (I was a newbie CCD imager then )

Nah, no can do. I have all my gear semi-permanently installed at a friend's place, so, pulling it all down, packing it up and taking it up is a hassle.

Also, the skies are inky black at my mate's place.

What head are you using between the camera and the polarie? I use a manfrotto ballhead with a rotating base and I can aim the camera pretty much anywhere in the sky. The camera doesn't come anywhere near the polarie.

Cheers, Leon!

Lincoln, I'm just using the standard ball head that came extra in the starter road back. I think I will need to buy a bigger ball head. Or I'm just not rotating my current one properly!

Cheers.

If you have the camera upright you wont be able to aim above the scp with a ballhead. Using the base adjustment roll the camera to one side so its in portrait orientation, then use the ball adjustment to aim the camera up a bit to get crux.

Great shot Humi. Nice sharp stars.

Yes the camera can be a bit tricky to get above a certain angle before it hits the limit of the ballhead.

I rotate the ballhead so the indent is behind where I want angle the camera. That gives a bit more play.

Or I rotate the base around and try again and that sometimes gets extra elevation or I hang the camera upside down and I get any angle that way! It can be a chore to frame the image though! A tiltable LCD would help there. Otherwise its get on the ground and look up at the camera under the tripod. Oh well, whatever it takes to get the shot.

Greg.

Thanks Lincoln and Greg. That's what I did last night and I think I have the hang of it now. Cheers.

This thing has reinvigorated the spark. I want to make more award winning images.
