On Friday night (May 19, 2017) the ETX-125 and I had a late date with some sky objects.
I was able to quickly align the scope and when I punched in Jupiter, I found the planet sitting a little below center. I was using the 32mm Plossl which gives me about 60 power. After trying to define the various bands (I could make out the two major bands) on the planet, I decided I would try again to photograph the monster planet.
My previous attempt and only my second time trying astrophotography, was a total failure. This time I was able to produce an image which didn't look like a blurry blob on my monitor. That image is below:
I think it is a rather good image considering this was my third time imaging. If you are wondering why there aren't any of the Galilean moons visible, the reason is simple. The planet requires one exposure, the moons require a different exposure. In order to to have both in an image, I would need to expose the planet, then expose the moons, then superimpose the planet on the moon image. There might be a way to obtain an image of both at the same time, but I haven't figured it out yet.
By the way, if you are wondering what I used to make the image above, it was MalliCam's SkyRaider AG1.2c camera. I shot a 30-second video and when processing the file, I ran it through Registax 6 to obtain the final image. Most of process was automatic, but I was able to tweak the settings before I saved the image.
One thing I liked about the tracking of the Meade was I went inside after acquiring Jupiter to prep the camera. I was inside for five or ten minutes and when I came back out, a look through the eyepiece showed Jupiter still in view. It was barely moved from center.
After I finished with Jupiter, I input M13 into the control pad and the telescope found its way there and when I peered through the eyepiece, I noticed a nice grayish ball slightly above center and looking about half as much bigger than Jupiter did at 60 power. I thought I could make out individual stars on the periphery of the dim ball, but I just wasn't sure.
My next target has been something I have tried to see for years...M101. I punched M101 in the Autostar hand controller and hit GOTO and the telescope moved for a moment or two, then stopped. I looked in the eyepiece and nothing. Well, nothing isn't quite right. There was stars visible, but in the central area there was nothing. It may have been M101, but all I saw was blackness.
My next target was M82. After a short period of movement the scope beeped telling me it is pointed to where M82 should be and when I looked, I could see a nice sliver of light pointed diagonally to the lower right of the view and the upper left of the view. I admired the view for a few minutes and decided I would attempt to image M82 also.
And then my power tank died. I had forgotten to make sure it had a good charge. Wishing I could kick myself, I came in the house to get batteries for the battery pack of the ETX and realized I didn't have the correct size of batteries.
The moral of this post...always check your power supplies!
