...because it seems there is not alot of Nexstar SE Info out there

The idea for starting my own website/blog came to me when I was looking for information about the Nexstar SE series telescopes on the internet. There are a couple of amateur sites out there (check the list of sites on the left) as well as the official Celestron website but I found that most of these sites were sometimes catered to the seasoned amateur astronomer and were a little difficult for me to understand. So I decided to write down my experience with this telescope so that maybe someone else might benefit from it. Oh - and I don't have any connections to Celestron - I only chose the orange color for the blog since I thought it would go nice with all the pictures of an orange telescope ...

shake it baby !


"the tale of the vibrating garage"
After a couple of months of really cold weather it finally got a little warmer last night, so i decided to spend some time stargazing again. I set up the scope and used a quick SkyAlign to get going. I received an "alignment error" two times and by the third time i realized that i had not set the correc time nor the correct date.

The alignment process only asked me for my location but never asked for a date or time, so i wrongly thought that it was not needed. But really, how should the computer know what date it was ? It's not like i've been keeping the scope in hibernate mode since last november...stupid me.

Anyway, so i then used the two star auto align method and spent about 30 minutes looking at M42. WOW. The moon was quite bright so i guess seeing conditions were not optimal, but i still liked what i saw.

So i got out my Panasonic G1 and tried out my bathinov mask for the first time. I chose a nice bright star close to m42 and took a couple of pictures and while fiddling with the focus i finally got it to look just like it's supposed to. Below you can see the two images. The one on the left is out of focus and the one on the right is in focus - or at least that's the best i could do:


I used 2 second exposures for these images by the way. So far so good. I then moved the scope to M42 manually and started taking pictures. The first picture was really blurry. You could hardly see anything. The second one was crappy too.

Then i realized that the bathinov mask still hung over the dew shield..... Sometimes i defenitely feel my 41 years....

So off the mask went and i stared to take pictures. I started with 5 second exposures with 400 ISO and went up all the way to 25 seconds with 800 and 1600 ISO. From what i could see on the G1s viewfinder i was taking very nice images. I was starting to feel proud of myself.

But when i finally got inside and looked at my great images, all images looked like this:


You won't hurt my feelings if you're thinking: "That looks like crap". Indeed it does. So i went and did the whole bathinov focus thing again and still ended up with shaky pictures. I then realized that whenever i moved, the image started to shake really badly. Even the smallest movements created really bad vibrations. Of course this is what kept messing up my images.

As it turns out, the roof of my garage is supported by wooden beams that vibrate like the floor of a boxing ring whenever i take a breath..... . By the time i realized this, both my power tanks were giving me a nice yellow light, so i had to pack everything up.

GREAT. Another two hours spent outside with nothing to show. But it was still great fun seeing that the bathinov mask acutally works and M42 looked really nice !

Looks like I have a LONG way to go until i'll end up with decent astrophotography....

But at least i'm BACK and looking forward to try the whole shebang again from my driveway which will hopefully prove much less unstable : )
