Besides the RKE, what other 3 element eyepieces are out there that people like?

TMB Supermonocentrics & AP-SPLs.

Become a Farmer? No.

Instead I became a <strong class="bbc">S[/b]olar <strong class="bbc">L[/b]unar <strong class="bbc">a[/b]nd <strong class="bbc">P[/b]lanetary observer (SLAP).
And double stars. Does that make SLAPADS?

But seriously folks... I gave up on the faint fuzzies back in the 90's. Works for me!

Wow. This is a great time in your club.

Start out like you mentioned with a few pads. Most folks do like to use their own equipment.

Think about security - not a lot you can do to a concrete pad. :-) Think about parking. Think about building some wind breaks.

Maybe a storage building for a few things. If there's no one living on the site I don't know about a lot of expensive equipment unattended. Never underestimate the ability of man to do stupid things. Think about power. If there's not electricity nearby you'll need solar. A couple of solar cells and a few batteries will provide plenty of power. Nothing wrong with lugging those out with you on the weekends your club stays over for a couple of nights. Take them home for security if you feel the need. One of those quiet generators is a nice alternative. The 90/10 rule is real. 90% of the members will watch the other 10% do the work. Not a problem. The 10% love it and the 90% don't know what they're missing.

Dark is more important than fancy.

Our club has a 15X20 roll off roof building with a covered porch, 12 concrete pads and we just added a Sirius fully automated 7.5' dome ( donated!). We are located on a bluff around 50 miles NE of Birmingham and the owner of the property keeps an eye on things and farms the surrounding land. Honestly most folks use the pads. We require a check out on the scopes in the building and dome. We have detailed instructions and we have not had any conflicts with the scheduling. The dome and building are nice for the imagers.

Go get the land!

Lastly - think about personal security too. 4 legged and two legged. Some of you will be going out there by yourselves. Get to know the local sheriff and most deputies love to look through the scopes!

Let us know how it goes.


Doesn't begin to wash for me, Jim.

Planets from the backyard can put you in a frame of mind that "more magnification" is all that matters.

Since you like math, spend some time poking around for a list of objects you might want to look at, and compute the eyepiece focal length you'd need to fill the view. Little stuff is still going to be little -- it's not going to fill the view, even at high magnification. Medium and large objects are a different story -- it's not that difficult to bump the magnification up to a point where you're only seeing a small piece of the object. That's definitely interesting in and of itself, but give yourself a chance to see "the whole thing" with a longer eyepiece, too.

I myself would by the Zhumell Z10. Its a much better scope! Sadly it is not a intelliscope. But theirs is 599.00 and they have free shipping and they do send it out the same day. I just bought the Z8 from there and I love it. It comes with some nice accessories and when you create an account with them and buy stuff and leave product reviews you earn plus bucks which can be used to buy other stuff.

You get 10.00 for creating an account and 10.00 for every 200.00 you spend and 5.00 for leaving reviews on your products. I earned like 40.00 and turned around and bought the Zhumell eyepiece kit that cost 89.00 which cost me only 40.00 since I was able to use my plus bucks. So each time you spend money; you earn money.

However the scope is nice. I am sure it is a lot nicer than the Z8 I bought. If you have to end up paying shipping for the 10inch Orion Scope, you will pay close to 100.00 just for shipping alone. I looked over the site I buy from and they do not sell Orion brand scopes.

<a>https://www.binocula...ector-telescope[/url] this is what the Z8 looks like and the 10 is the same only 10 inch!

Here's a random thought: what if you mounted a laser pointer on your refractor, and use it to star hop to all your messier targets. Then just aim the C8 along the laser to complete the catalogue.

A Nexstar SE is obnoxious to manually drive around even if you know where your targets are. They are really not made for it.

I think you might be overstating things a bit given the context of this discussion. Every single person who owns an SE (including myself) has to manually slew to at least two targets (for alignment) every single observing session, and we all survive the experience. If the OP were to attempt 10 messier objects per session, I think that would be pretty manageable even with the hand controller.

It's not February 1st here yet. If you consider California time it looks to me like they have another 27 hours to make the deadline.

I acknowledge that. They are marketing worldwide however, and never specified that it would be that restrictive. I am ok to wait till the 2nd now, California time or mine, as long as there are no bugs in it.

I've had a 10" dob for a couple of years now and have really liked it. Very simple and fun to use. I did build a cart that helps a lot with getting it out of the house. The telescope is not super heavy, but awkward to carry, and the cart lets me go out in one trip. It's also got a wooden riser that brings the eyepiece up to eye level when I use it, or can be removed and used as a stool for kids.

Nice cart, is that Styrofoam on the back of it to keep it stable?
Thanks! The styrofoam is really just a spacer so the telescope doesn't move when I tilt the dolly up. I have a van and just throw everything in the back and buckle it in, haven't even really had any collimation problems. It's hard to tell, but the upper foam is firm, but softer than the construction foam on the lower part, so when the tie-downs are tightened, the OTA kind of squishes into it a little.

The filter feels like it wants to start cross threading about half way. Is this normal? It also will hit my baader prism so I had to 3d print a 7mm shim for it. CN won't let me upload STL files so here's a link to the 3d model if anyone wants it:

I found the 10 and 23 good to about 80 percent of the field at f 8 . With a 2x barlow, so working at f 16, good to the edge. The 4 is just bad. Some suspect the 4 is just the 10 with a bad barlow built in.


If it were me, I'd lean towards the 32 mm. The field of view is still very wide, 1.91 degrees, and the added magnification will be useful under dark skies.


I agree with those saying get a wider afov eyepiece. This is your perfect opportunity to do so.
Pan 24
Pan 22 (used)
Meade Series 5k 24/68 (used)
ES 24/68 (new or used)

good luck!

I wonder why we spent so much time inventing mounts that find/track, and so little on cloud control.....

Beginners Forum / Re: Orion Intelliscope option
« on: January 31, 2018, 12:06:04 AM »
I have the Orion XT8i and I love it. I use the computer about 50% of the time and manually the rest. When you consider an XT8 configured in a similar fashion to the XT8i the cost difference is about $110. Cheap insurance to see that you can find the things you want to see.

A good example is a comet that ispassing earth, comet Catalina. I looked it up on Stellarium and got the RA and DEC coordinates. Then I used the digital setting circles feature of the Intelliscope to target the comet. Worked great!The Intelliscope saves me time as my observation sessions tend to be short, usually about an hour. When I have waited out a week or more of clouds and have an hourto observe I want to spend it on the target not looking for it. And I don't always have the time to lay out star hopping charts and plans.When I do, I leave the computer off. When I don't, I turn it on and go to my targets with confidence.

I think you will love it!
