its called Angle Meter by Jin Jeon .....its free.
- Rotate the camera by hand to any angle that you choose. I had to rotate so my FW and OAG would not crash into the mount when it was slewing around.
- Once you rotate the camera by HAND, open up that free app and just place your iphone against the side of the camera or your FW (we have the same setup I believe) of course this will not be a 90 degree angle because you just rotated the camera by hand ..........make sure the entire mount is LEVEL FIRST. What is cool also is that the CHIP is oriented perfectly to reflect the camera angle automatically , that is why if you plate solve is should show the same angle as your iphone !! OK, so now your iphone free app should tell you the angle of the camera, which should be the same , or really close to the same, if you took an image and plate solved it ....it doesn't really matter if you use the iphone app or not , its the plate solve that will tell you what angle you are at ........ok , now for the fun part.....
- Lets say you figured out your camera is at 28 degrees (iphone says so and so does the plate solve of any random image you just took).........ready ??
- Open New Sequence with Profile (I assume you have setup a profile of your equipment ).
- Open Framing and Mosaic Wizard.....the camera info will automatically fill the necessary fields under Camera Data.
- Just for practice, enter M42 in the Object window under Fetch the Target Area. then click on FETCH .
- Now the magic begins, you should see a nice pic of M42 on the screen. You can adjust the brightness using the historgram stretch window in SGP....move the black point to the right till you can see M42 clearly.
- Now in the Framing and Mosaic window find the Rotate selection slider under number 3 Define the Target. Make sure draw the target rectangle is ticked. OK, mess around with the rotate slider until it matches the angle of your camera !!! . If it won't match exactly start using your left and right arrow keys on your computer keyboard !!
- Next Draw the Target rectangle , click on M42 and drag the box so it surrounds M42 and release !! BAM,....now you should see a number of panels with an OVERLAP !! You can adjust the overlap back in the Mosaic Wizard to anything you want, but at 20% to be safe so you have enough stars included in the overlap , heck, I use like 30 or 40% sometimes. You can grab that rectangle and move it around all you want , check out number 4 on the Mosaic Wizard, you can adjust the number of panels (tiles) also.
- When you get M42 framed just the way you like it (do NOT change the rotation ) just click "Create Sequence", a window will pop open titled Mosaic Sequence ( you could UNcheck the auto rotate or validate rotation on mosaic start, that will save you some hassle )make sure Precision centering with Plate Solve is checked....... then click OK on that window and watch it fill in all the needed info for the Sequence !!!.
All that is left is to choose the filters and exposures you want for each Event .
Best part is you can do ALL of this during the daytime over and over and over just for practice and SAVE the sequence for your night run !!
Cool , don't ya think ???
p.s. hope I didnt' make any mistakes along the way. Let me know how you made out .......any questions don't hesitate to ask....we are all in the learning mode ...
