I need some advice on Lenses I bought a Celestron Nexstar-8 it came with a

40mm lens what other size lens should I buy first.

A lot depends on what you are looking to see. I'd get something in the 12mm range and then maybe 20mm range too. 40 mm is nice and wide but not very powerful. If you are in town I think I have a 25 mm Plossl I could donate to you, and you would be more than welcome, if you bring your scope over, to use the better lens I have too. I have a pretty good selection you could pick through.

Hey if there was one and I found him I'd be pumped. Maybe he is just gone away and thats why there are no miracles anymore.

...and no Insane Clown Posse posts please and thank you :)

How much does a set like that cost?

My understanding was that the shots you are taking could only be seen through some sort of university or research project that would cost tens of thousands of dollars to put together.

Well his exposures are over 2 months time and yes that is what really tough about doing this. Usually you do 10 minute "subs" at a time then stack them in software to gather all the light from the different frames. If the scope varies by 1/32 of the width of a human hair anytime during the 10 minute subs the shot is ruined and you have to toss it out.

The mounts that guide the scopes for the pictures are insanely complex. And expensive for the really good ones.

I think used, if you aren't looking for REALLY distant galaxies you could put together a reasonable little setup for $2,000 - $3,000. $5K buys a nice setup. I've seen guys that do the top of the line shots spend $200k easy.

That's so much cheaper than I thought.

Thanks Dave, Trying to pick up some quality eye pieces on ebay.

I'm in Texas now other wise I'd like to meet you and learn more, maybe a rain

check when I get closer to KC.

Absolutely. I'd try to get a couple Naglers if you can swing them. Also get the 2" versions if you can do not buy the 1 1/4" unless you have to. Buy a 2" diagonal preferably 97% reflectivity and you should get some great views with your scope.

Also Google "SCT collimination" online to see if your scope is got its two mirrors centered and aligned. It makes a huge difference in your views.
