8" Starfinder on Equitorial Mount new
      #6033944 - 08/19/13 03:38 AM

As in the title.. I recently purchased a new scope for about 100 bucks.. (USD) I want to know if anyone has done something with this scope to make it kick butt, No idea is too silly. I am open to everything and anything. To start with.. The reflective coating has some.. "Flaking" as far as I can tell.. It doesn't affect the quality of the image. Should I start by getting it resurfaced? Or is it not worth it?

Also, is there anything I can add to it.. or any accessories that might help?

It should be a very solid, competent scope. As with any new scope, the first order of business is posting some photos.

How are the views?

A dual speed focuser is a nice upgrade if it doesn't have one already.

Jon: Views are great. Using a modified camera for pictures. Moon looks great!!! So does Venus.. but pictures of Venus look like garbage. Lots of distortion that I CANNOT FIX. I plan on getting a webcam soon.

John: how much would a decent one cost?



Thank you so much

I've got MoonLite focuser on mine but they're fairly pricy at around $300 but excellent quality. I get a lot of use out of it and appreciated having the ability to use fine focus. I believe Orion sells more economical focusers at around $200. That's the thing with astronomy accessories and eye pieces. They can often cost more than your telescope.

I had the 10" version years ago. It was capable of great performance when it cooled down and sky's cooperated. I do however seem to recall finding out that the secondary was undersized, so that's maybe something you might want to check on your scope.

Are you solo or do you have others you can stargaze with? You will benefit from getting to look through other scopes and having others look through yours. Most amateur astronomers would allow you to try their EPs in your scope. This is also a great way to find out first hand about all the accessories you read about here like the Sky & Telescope Pocket Sky Atlas, Telrad finders, etc.

My whole family thinks I am looking for aliens. I still live at home. Can't get emancipated at 16 in MN. So I am by myself unless my friend from MPLS comes down. (I live about 115 miles away from the cities.) to be honest they shun me. But I like being alone. And what are EP'S?

How would I find out if my secondary is too small?

Well Here is my picture of Jupiter (I have everything figured out to fix it. Just haven't had a clear night and school is starting soon.)

The zoom is excellent. It's the camera cause the moon looks great!

Easiest way to check your secondary is just to measure the minor axis (the narrower width of the ellipse) with a tape measurer (careful to not scratch the mirror) and then use the online version of newt (just search newt on the web). Newt is a great program which is now hosted on the stellafane site and lets you plug in the particulars for your newtonian scope and figure out everything from how big of an illuminated field of view you'll get with a particular secondary to magnification and true FOV with any of your eyepieces (EPs). In your case you want to make sure that for your scope ( an 8" F6) with your secondary mirror size (that you measure), the 100% illuminated FOV is >0. If I remember correctly it was not for my old 10" but that was a bigger scope and F4.5 (so naturally needed a bigger diagonal). Don't be afraid to play around with it. It's fun (yes I'm a geek) and a great way to learn about newtonian scopes.

the secondary is about 1.8" if I remember correctly...

If that's the case then it should be fine... it is possible that my 10" also just had an out-of-spec secondary. I had bought it when I new little about scopes other than that bigger was better (and that was as big as I could afford). I remember being very surprised when I actually measured the secondary years later. At that point I was already in the process of building a custom scope and the meade got parted out so I wasn't that upset. It did give me some wonderful views over the years though the custom scope that followed it was much better
