If it is about the weather then you all should shut up, here in my country the summer starting by May, sometimes earlier by late of April, and about humidity also shut up, i am inside my room and i must put my air condition at full speed or maximum cold to feel nice.

Degrees in C during summer in my country as about 32C degree during the night and 45-50C during the day time, humidity is around 70-90% during the summer, i think above 40 degree is something like 100 F and above? and i can't see stars good enough same as where you are, so no great view, light pollution, HELL HEAT and humidity, i think my big mistake is that i got the equipment and trying to start AP in summer, maybe i should rest for about 3-4 months then i will go out for AP for sure.

This link showing the temp in my city nowadays, and the summer just started, you can't imagine how it will be by July and August

No i don't live in a desert, but UAE was a desert 95% and few mountains around, we built about 30% of UAE area and the rest is still desert, but i will tell you something, the temp in desert may be very hot but not very humid, while we live along the coast so the humidity is so high, and the areas around the mount is fine mostly those far from the sea, but the big cities from Abu Dhabi to RAK are mostly next to the sea level, so the humidity in the city is worse than the desert to be honest.

Martin,

I will try your technique next time I am doing high power viewing of the planets and moon. You got me curious to see if it will work for me!

I want to try it too but I'm afraid that if I keep my eyes perfectly still they will tear up. 3-5 seconds should be manageable though.

It's lubed up pretty good now, but yeah, the RA axis will probably come back apart soon. Dec is really free now, but the RA is probably about the same as it was before the tear-down. The bearings themselves felt nice unloaded, but I didn't mess with the seals to look inside the non-tapered ones. It was stiff before I adjusted and snugged up the worm housing.

Hi all,

Resurrecting this thread only to say I have finished my project. Thanks to everyone who provided guidance. In the end I drew inspiration from Howard's Springsonian design (thanks Howard!). I also referenced this website, which shows the configuration used to provide telescope access to the handicapped. (http://www.dalekohle.../vozickari.html)

It's a 10-inch f/3.8, which I made on my own with sonotube and plywood. My workmanship is very poor, but the motions are smooth and it balances nicely. The bottom white part is your standard dobsonian azimuth box, to which I bolt black plywood side walls in an attempt to make the mount portable. RFP and teflon for altitude & azimuth. The stringer is made from a metal broom handle into which I inserted star nuts. The counterweight arm is 2"x2" wood attached to the cradle with bolts and t-nuts. I strapped an iron bar to it, and use standard barbell weights attached to a bolt which slides into an aluminum channel so the counterweight could be easily adjusted to find the right balance.

With a Paracorr and a 31mm Nagler it is 35x and a 2.3 degree TFOV -- not quite as wide as 25x100 binoculars but with plenty more light gathering and far more comfortable to use. With an adjustable observing chair, young persons and adults of just about any height can find a comfortable position to sit and view. I use it as a companion to my 20-inch for wide views and "resting" from being up on the ladder.

The mount proved its utility the first night I had it out. It was a public event with a local club the night of the recent Jupiter / Venus conjunction. While other scopes needed the viewers to crouch or kneel on the ground (the dob) or get on a step stool and crane their necks (the SCT), I could track it all the way until it disappeared at the horizon while sitting.

I had the telescope out to a dark sky this weekend. The dark nebulae were breathtaking. M31 stretched well beyond the FOV but I was able to track the M31 IFN "shelf" Mel Bartels describes extending below M110. I was noticing the foggy IFN a lot around many targets in the Milky Way. I had an amazing view of Mars on one end of the FOV, with M8 on the other, with a globular and an open cluster in the field too. When I returned to it the next night, Mars had moved out of the view -- astonishing to me that it moved so quickly. The California Nebula, half of it in a FOV, contrasted with the dark sky background and with wisps and tendrils throughout... M42 showing its complete bubble form... It's a wonderful scope.

Now I need to get out and find me a comet!

General Astronomy & Observing / Re: Observing vs imaging existential crisis

Well, somebody's got to say it.
A simple first world, rich peoples' quandary over which is the preferred outlet for excess income hardly rises to the level of an existential crisis.
And yes, we all have to pick. Some between G5/G6, some between bread/meds.

Yes. Thank you for this correction. Sometimes it is good to step back and try to observe ourselves objectively.

I know for that i had a orion xt10i and had to clean the mirror and there was wiggle rm with that one to it actually had Teflon screws that tightened against the edge of the mirror held it in place instead of clips

I just ordered a Celestron RDF from Amazon, so hopefully that will help.

I bought the SkySafari Plus app, hoping it would help, but it has some issues: I don't have a convenient way to mount my phone in the plane of the mirror. I was thinking that the telescope align thing could let me mount the phone perpendicular to the mirror, and then I could align on some known stars, but I guess that's not how it's done. Also, the accuracy of the compass is pretty lousy, so it's pretty far off.

Eyepieces Questions & Recommendations / Re: Eyepiece upgrade time

I'm about to upgrade from stock. I have a nexstar SLT 130. It comes with a 25 and a 9. I've done a lot of research and going to go with the celestron xcel lx series. Wish I could afford more expensive, but 65 a piece sounds pretty good.
Should I stick with 25 and 9 or go for different size.
Also going to get a 3x barlow of same. Already have a 2x omni barlow.
I'm not opposed to going with a different brand. Just can't spend too much.
Thanks, and cLear skies to all.
OK, it's a 130mm 650mm focal length.
Seeing as how you already have a barlow, I'd say:
Get an 18mm and a 12mm.  With the Barlow, that gives you a 9mm and a 6mm
So a set of 18, 12, 9, and 6mm, for 36x, 54x, 72x, 108x
All are very usable magnifications in that scope.  And all would be 60°.
If they're too heavy, try the Astrotech/Starguider eyepieces, which are a little lighter and have the same AFOV.
Or the TMB Planetary clones (many different brands).
I'm familiar with your scope, and the X-Cel LX shouldn't be a problem for that scope.
The 130SLT focuser is not going to handle X-Cel LX eyepieces too well........ Neither is the SLT mount.. Tried them at SCAE, I didn't trust the focuser enough.
I never would have considered the X-Cel to be heavyweight in any sense ... but then I've never seen the focuser on an SLT 130.

Jonathan don't think like that! "I had it kind of coming..." is not where your mind should be. You are the paying customer and deserve a working product. As a Senior Director of a software support operation my team understands that the customers expectations must be met and that losing one customer due to poor support and service is unacceptable. In this thread alone I see 2 people who have abandoned Celestron mounts. No doubt that the US support team at Celestron is under pressure due to the use of sub-standard parts in the electronics. It only takes one component that is outside of the specified parameters to cause these types of problems.
But, that is not your concern, it is theirs. If they want to maintain a faithful customer base then they must provide you with excellent service. Hopefully, they read these forums and report back to the powers that be. Of course support will put you through the mill on your power supply, HC and all the rest. Be patient, prove your position as you have, and keep posting progress in here and if they get difficult let them know that you are discussing progress in this forum.
Good luck, and don't give up.Phil

I <em class="bbc">would become a hermit, if I had enough dough to buy a big swath of land in the NM mountains, plus enough to get by thereafter. (not going to happen, but it's a nice thought)

I collimate indoors with a laser. Indoors it is hard to reach focus, so it is hard to tell if collimation is off without any tools. You can get a rough idea just by looking into the focuser. If there is a bright object out the window, like someone's porch light, you could try that.

Hello and welcome from a fellow Mainer.,I'm up near Farmington.,with pretty dark skies. A planisphere is a great tool for learning the way the constellations move across the sky.,and to show what part of the sky is going to be viewable for each night. Learning the constellations is key to helping you to find all the faint fuzzies. Using bino's through the window is how I started to learn to star hop.,my 7x35x bino matched the charts just about right for what stars I could see with them.,and it's fun not to freeze.,Good luck.,,stay warm.,get to a club meeting if you can.,

So, where canwe move that still has Bortle 1, Dark Site Finder “Black” skies in the continental US? If not in CONUS, any place that’s within striking distance of the continental US? [Couple hour flight to a major US airport as I don’t do long flights well anymore. ]
We’re considering looking at Eastern Nicaragua. Costa Rica was nice but not any better than a DSF “Blue”.


The only thing you'll find within a 2 hour flight from the US, is an international airport, which means a large city.

A little farther away (one extra connection) is Galapagos islands. Perhaps too remote, but look for "Puerto chino" beach on dark site finder, and imagine that place in the dry season.

That place is in my bucket list for vacations
