Reflectors Telescopes Forum / Re: Moonlite focuser vs GSO 2 speed
« on: February 09, 2018, 10:28:19 AM »
I have a Moonlite on my 16" and a GSO on my 8". The Moonlite is better and I will always choose to buy it over the GSO; however I wouldn't bother to replace the GSO with a Moonlite unless I had another use for the GSO.

for your budget, perhaps a Meade 32mm super plossl and an omni 2x barlow? It is a short style barlow so would work with your diagonal I hope.

Well my scope showed up today. Took about an hour to get it put together. I checked the collimation and it was not bad, but I thought I could get it closer. Besides I just received my Hotech SCA collimation laser and had to learn how to do it. I made it worse! Took a deep breath and started over. Then it went smooth and I got the laser dot centered on the primary. The primary went much smoother. I was pretty happy.

I took it out tonight. First I had to align the finder scope. Did this with Polaris in the eyepiece.this went pretty well. I didn't get a chance to read up on theIntelliScope Object Locator, so I thought I just play with it manually and get comfortable using it. Looked at a few stars and just scanned the sky. Very nice views with my Orion Ultrascopic 35 eyepiece. Then I decided to try star hopping. This would be my fits attempt at it, since I always had ETX 125 go to. Cassiopeia was looking good, so I thought I try for M52. So I Started at Cassaepia Caph then worked my way to some smaller stars and found it. Very nice cluster. Then I thought I try for M57. Got my scope lined up with Vega then worked my way to , from there it was easy to get to M57.

it was a great night out with new scope. Being able to use it manually was great fun and one of the reasons I bought it. I'll read up on the object locator and learn to use it, but it's nice knowing I dont have to rely on it. Thanks for listening.

ATM, Optics and DIY Forum / Re: Yellow coatings on mirror
« on: February 03, 2018, 02:19:11 AM »
If the mirror is overcoated with SiO then the thickness of SiO coating can cause the yellow tint. The coating acts like an interference filter and depending on it's exact thickness you can get interference at a specific wavelength. If you look at a different angle does the color change ?

Dave is right on.

You are doing a cold start to build the pointing model after you entered the basic setup info?

You said you have the date and time set correctly, just for grins try setting UTC offset to 0 hours, and set time and date to Greenwich, (UTC time) with your local lat and long as location. Just a check to eliminate any local time and offset error.

Have you viewed the Losmandy youtube videos on the basic setup functions, might be some thing that you missed:

Sequence: Cold Start _Modeling_Select East / West star_Goto_center the star_ Model_ Align_displays model errors_ Back_ repeat the sequence for as many stars as you wish.

When you start the alignment you mentioned "sync" on the first alignment star, you are not saying you are using the synchronize function in the hand control menu? That is used if you accidentally bump the mount when you are already up and running and need to correct it back to where it was pointing when it was disturbed.

I am a high school Physics/Engineering teacher at a small PBL based high school in Evansville, IN. (http://www.evansvill.../real-world-now) In my teaching experience of 31 years, I have introduced students to Astronomy with borrowed telescopes or telescopes that I have picked up at yard sales. ( http://www.cloudynig...-i-ever-spent/) That first year I showed students sunspots, and the rings of Saturn; one of those original students became a science teacher and is now my principal!

I got away from Astronomy for several years but got the bug again last summer after finding that RV-6 last summer. I have started an Astronomy club at our high school and have recently acquired a Celestron 8SE from a donor. The kids and I are very excited, but the weather has been rotten for some time. However, with the solar eclipse coming in August of 2017 we have a unique opportunity as we are only 70 miles from Hopkinsville or Princeton, KY which will have a 2:40 second duration of the eclipse. We plan to take all of our students to experience this once in a lifetime event, but I want to them to see this in a number of different ways. This is where I need your help, and the members of Cloudy Nights have been more than helpful on several occasions in the past.

I want to purchase a dedicated solar scope (Lunt or Coronado?) , tripod, a video camera, and a solar filter for the 8SE, along with several Sunspotter Solar Scopes. What equipment would you recommend for this? Is there anything that I should be considering?

I have a number of goals with the Astronomy club’s future:
1) To get my students comfortable enough with the telescopes so they can do outreach programs at other schools and with adults.
2) To build an observatory so the school can have access to the telescope from their computer at home. Our school is in the Career and Tech Center and the students have the ability to design and build the observatory under one roof. (http://www.edlinesit..._Programs/SICTC)

You guys both brought up binos, I have a decent pair of 10x50s, Should I just stick with those? They do fit all the criteria, I just thought a scope with my eyepieces might be better.

I don know. I think a pair of 15 X 70 binocs would do the trick. They meet ALL the requirements. Just my two cents...


Beginners Forum / Re: First Telescope? - Celestron Nexstar 8 Telescope
« on: January 31, 2018, 05:51:12 AM »

I'd get the motors and computer checked out thoroughly before getting a proprietary tripod for it. You may find that you'll need a whole other mount of some sort, a manual alt-azimuth or equatorial, and $200 can go a long way towards same.

...something to think about.

You would not use oil so much, but a good-quality grease, and sparingly...

Thanks, I will buy this grease and hope that it will make motor function a bit better.
Moving the telescope vertically is not smooth. I can also move it by hand but try not to.
Be sure to clean the old lubrication out thoroughly before applying the new, and it's the gears that usually need lubricating.

I would research that particular mount online and search for disassembly and cleaning articles. If it's an SE mount, no, you will not be able to move it by hand, and hope that no one else did either in the past.[/quote]
It looks like original mount but moving it by hand vertically is quite easy.
It's not an SE mount, it's previous generation mount.[/quote]
The manual...http://www.company7....ar_8_manual.pdf

"In case of a loss of power, the optical tube can be moved by hand. However, when powered on, the telescope should always be controlled via the hand control. The NexStar will lose its star alignment if moved by hand when powered on."

The SE allows for altitude(up and down) manual motion only. The older yet near-identical NexStar 8 mount may also only allow movement in the altitude as well. If it doesn't move in the azimuth, side to side, don't force it.

I've never had a problem with ADM and I've ordered several items from them over the last few years.

Reflectors Telescopes Forum / Re: M101
« on: January 31, 2018, 04:11:36 AM »
Ok I've been getting familiar with my Z8. Collimation, bobs knobs, stronger springs etc.
I can find M81/82, M13 and the usual suspects.
I'm going to vent my frustration at finding M101. I'm not a complete retard salad and can read star maps, star hop, the basics. Is M101 more diffuse than other galaxies? At magnitude 7.whatever I should be able to hunt the sucker down n hawkeye it. True, seeing has been iffy as of late but it's not a total soup sandwich. Any advice?

Have you found/seen M33?
It's about the same difficulty.
Use your lowest power to find.

I experimented at our dark site with an Orion UHC Filter on both M57 as well as M17 (probably not dark by the standards of some). If it did anything it made the object more dim. I donmt believe there was much of an improvement. The Orion may not be as hight quality as others, but if it were me I would get a nice 24 Panoptic or an Olivon 22mm and go that route


A real looking Ring nebula from my 80mm refractor.

There ya go... definitely not "all jazzed up".

I am going to take a hard look at the Baader Zoom sound like it may be just what I am looking for, thanks.

The thread of each screw extends below my pier mounting plate and I use nuts on each screw, and tighten them after the mount is level


Hi Bob,
Your comment about vibrations that can be caused by the levelling screws is valid.
That is why I made completely different ones with a locking system for the one I was trialling . These removed any movement in that department.
Thanks to both of you.
I'll modify the screws and add the thick plumber tape.

I also confirm, after a second test on my flat roof this afternoon, that hanging the counterweight with a short wire instead of screwing it on the bar greatly reduces vibrations.

Thanks for the tip Don. I have the color filters, although I don't use them very often because I've never seen any improvement from them. However, from what you say the Baader Contrast Booster filter sounds interesting. I may have to flex my Visa card again.

How does it work on Saturn and Jupiter?
