I get back from the star party to find this?

I thought the acrimony was in "refractor vs reflector", guess I'm wrong.

Please let me explain further about Gen-X Astronomy:

First I apologize to those who seem offended, please understand the site is "for", not "against" any person or group. I did not start this post to polarize the astro-community, or start a flame war.

"Under 40" is perhaps not the best terminology. It is simply my experience that *currently* most of the people in my age group are between 30 and 40.
Among the active observers in our area and age group, there are only two that I know of. One is me.

Gen-X Astronomy is just my tiny piece of the internet that I use to say "Here I am, this is what I do, if youre similar, speak up"

I dont understand some of the posts that are downright negative. I thank those that had something nice to say, its appreciated.

Try a Type 6 Nagler. They work good in every scope, even my 80mm f/4 and 50mm f/4 finderscopes.

I was able to see this wonderful event from a dark sky site near Midlothian, Virginia. Luckily I had a good western horizon. I watched the star for a few minutes until it disappeared. It stayed hidden for about 3 minutes, then appeared briefly for about 5 seconds. It stayed hidden again for about a minute. By this time Venus was behind the distant pine trees.

I have seen many thin crescent occultations of stars by chance, but I have never seen a graze. I deeply regret not having recording equipment. I was using a 6.5" f/5.5 scope at 50x.

From David Dunham's map the graze path went right thru central VA. To my best knowlege my position was
a few miles north of the graze path.

I also wish I had my moon map, I dont get many chances to view such a young moon. The earthshine was magnificent.

I have a Stellarvue clamshell for my 80mm scopes. I find it much preferable to the mounting options standard with these scopes. It has two large thumbscrews to loosen/tighten.

The Celestron scope's paint was damaged by the screws on its original rings.

For larger scopes I reccomend the Parallax rings or similar.

Look at this :

Celestron E-Lux 32mm 2" Eyepiece

[COLOR="Blue"]Good advice:[/COLOR]
A buddy has a similar ep and it works ok in an f/5 dob and its a bargain. Works "ok", not great.

[COLOR="Blue"]Best advice:[/COLOR] get the 35 or 27 Panoptic. You only really need one 2" low power ep and the Panoptics are the best. Telescopes come and go but good ep's are a lifetime investment. You have a large scope with decent optics you might as well make the most of it.

Good Luck,

Thats happened to me too. Check this guy out...I didnt get a rating from him. A little lopsided in the ratings???? I can understand one or two but this???

After a satifactory transaction I left the seller 5 stars.. down the road apiece I noticed I did not receive any stars whatsoever.. I left a memo in the "message box" as a reminder..still no response. Then I saw what I think is the reason why I probably won't get any acknowledgment.. this user has received over 130 rates and has given 60.. end of story.. JM

A trade is just like a deal, except you're exchanging goods for goods, instead of money for goods. You may get lucky and get a reply in 5 minutes. Same rules as any other deal, I believe.

My opinions on a good trade:

1. describe clearly what your looking for
Condition wanted: like new/ used/ some wear ok/ beat up ok
Made by:
When manufactured:
comes with:
Include photo.

2. Same applies to what you are offering in return trade. Honesty is the best policy.

3. Be ready to purchase outright if someone only wants to sell

4. Clearly state +/- cash if not equivalent value

5. "Each person responsible for own shipping" reccomended. Exchange of tracking # reccomended.

6. Dont deal with anyone who wont give you a firm commitment. Just politely say no.

7. Respond to every reply, especially after trade pending. Dont leave people hanging without a reply.

8. Update your ad immediately when "trade pending"

9. Dont forget to leave feedback. If they dont give you feedback in two weeks send a reminder email. If you dont get feedback after a month, go to your account and delete the good feedback you gave them. Its only fair.

Most Astromarters are good people. You wont have to search far to find what you want.

Good Luck,
John

I have bought and sold items on Astromart. I am considering offering an item for trade. Can someone point me to the rules regarding trading on Astromart? Thanks for your help.

... But I need to buy a telescope based on specs and without prior firsthand experience.

Jackie,
Do you buy a car without a test drive?
Buy a house without seeing the inside?
Marry without going on a date(s) first?

While Im here, can I borrow $10,000? It doesnt matter that you dont me and I dont know you, I'll pay you back, "promise".

1. See you local astronomy club for firsthand scope experience and free advice. Please dont be one of those people that shun astronomy clubs.
2. Read your "Starware" and "Backyard Astronomer's Guide" available at library and bookstores
3. Speak to one of the helpful people at Anacortes Telescope
& Wild Bird www.buytelescopes.com
4. A longer focal length will give higher magnifications than a shorter focal length. Look to achieve a high enough magnification for planetary study while using longer focal length eyepieces.

4" (100mm) f/6 refractor with 20mm ep =
[COLOR="Blue"](scope fl = 600mm / ep fl= 20mm) = 30x[/COLOR]

4" (100mm) f/12 refractor with 20mm ep =
[COLOR="Red"]1200 / 20 = 60x[/COLOR]

The focal ratio will help in dtermining the exit pupil with any given eyepiece. Generally useful exit pupils are between 5mm and 1mm. An f/12 scope with a 6mm ep gives a 0.5mm exit pupil, too small for some people. A f/6 scope with a 6mm ep gives a 1mm exit pupil.

An f/5 dob with a 40mm ep gives a 8mm exit pupil, too large for most applications, as the secondary abstruction will be visible, especially in ligh-polluted skies.

Its easier to get high magnifications with a longer scope, without resorting to barlow lenses and extremely short fl eyepieces. Hope this helps. Look into a Televue 102
