JMI Polar scope on G11
|
Doug Culbertson
Here's what may be a silly question. I recently received my G11 and
bought the JMI version of the polar alignment scope for it since it was available now. Is anyone else using the JMI version? If so, what did you find as the most convenient place to put the Velcro tab to hang the illuminator control? Apparently the battery holder/controller can't be disconnected from the polar scope without voiding the warranty, if I read the paper that came with it correctly. Thanks! Doug Culbertson Midway, FL |

Is anyone else using the JMI version? If so, what did you find as theHi, I have no experience with the JMI version but my battery and cord is velcro'ed in place inside the semi-pier. I just let the cord hang down through the bottom of the pier then up behind the drive electronics. I just plug it in when needed. At some point I want to mount an on-off/dimmer switch but it will have to wait for a cloudy winter night. Cheers, Bill |

Doug,
I velcroed mine to the outside cover of my encoder. Use a tab of glue or something to hold the velcro in place. All of my velcro keeps coming off the back of my illuminator switch. You have a very good polar finder. It is roughly 6x in power. Take care, Gregory david Stempel FIREFRAME |

Thanks Gregory and Bill,
Both are good suggestions. I don't have the encoders, but I was leaning more toward mounting it on the head itself so it does not dangle or get in the way while putting the head on the tripod. I agree, it is a very nice polar scope. It was suggested that I go with the JMI for two reasons: 1. it works 2. it is available! Of course, it has been cloudy ever since I received it, so I may NEVER get to find out how good it is!

I think I missed part of this thread. Functionally what is the difference between the JMI Polar Scope and the Losmandy unit? Just curious... Thanks -David On 17 Aug 2000 16:42:19 -0000, Doug Culbertson wrote:

I just got a Losmandy Polar Scope, but was told by several suppliers, that they use the same optical system, but the JMI has better electronics (i.e. it _has some_ electronics) to control the brightness. (and it costs about $70 more...) Robert. -----Original Message----- |

From what I have been able to tell (I have never actually seen a
Losmandy polar scope) they do have the same reticle as the JMI unit, so functionally they should be the same. The illuminator seems to be more or less permanently attached on the JMI and, as I said earlier, the instructions say it will void the warranty if you remove it. That was the reason for my question as I had the impression that the illumination gizmo on the Losmandy version could be removed. The JMI illuminator dims on its own; that is, you press a buton which illuminates the reticle and over the next several seconds it slowly dims until it shuts off. It uses a rather expensive battery, but according to the literature that came with it, the battery should last something like 10 years under "normal use" (whatever that is!) Is it worth $70 more than the Losmandy unit? I don't know. All I know is that I was willing to pay that amount just to have the polar scope now after hearing instances of the Losmandy model taking up to 6 months to arrive.

I have been trying to get a polar alignment scope for my G11 for about 6 months but keep getting told they are not available. The JMI EZAlign for Losmandy looks really interesting but I can't find any info on it. The JMI page says, 'Attaches in the normal position'. Umm. Is that normal for a Losmandy mount or normal for a JMI polar scope? i.e Does it mount in the bore? Thanks Regards Eddie Trimarchi ~~~~~~~~~~~~~~~ -----Original Message-----

¿ªÔÆÌåÓýHi Eddie, The JMI EZAlign mounts in the same place and in the same manor as the Losmandy polar scope. We have sold many of them for both G-11¡¯s and GM-8¡¯s. From what our customers are telling us, they work great. Thank you! ? Ray York http://www.buytelescopes.com Anacortes Telescope and Wild Bird ? ? -----Original

Eddie,
The JMI will attach just like the Losmandy. Inserting it through the center of the RA shaft. It is a 6x finder, comes with a collar that allows it to be tightened into place using the threaded area available at the end of the RA shaft. A small nylon type led then screws into the finder. It allows focus with no problems associtated. The tightening collar then has it's own set screw. You can then turn the alignment finder to align the ecthings on Ursa Major and Cassiopeia before polar alignment. The vf is illuminated for 15 seconds starting with the brightest illumination and dimming over that period. Usually, it takes two to four pushes of the activation switch to get a good alignment. There are indicator etchings on the glass for epoch 2000 and 2010 as well as 1950. You can use two stars to aling on. There is an etchng to allow for a third, but my skies have never allowed me to see that one. After a maticulous alignment, my GM8 tracks very well. Take care, Gregory david Stempel FIREFRAME |

Thanks! I forgot we spoke of this briefly last time at Lake Sonoma. Sounds like a great alternative. -David On 18 Aug 2000 18:00:52 -0000, Robert Leyland wrote:

Hmmm - sounds like the illumnator is a bit fancier. I have an older Losmandy polar scope, the illumnator is detachable and the control box is heavy plastic with a rotary brightness control / switch, apparently they are not coming with this control unit anymore. -David On 18 Aug 2000 18:00:52 -0000, Doug Culbertson wrote:

But for me to align on Ursa Major, I would have to have a transparent floor, and a hole drilled through the planet. Too much effort for me. I think I'll just use Sigma Octanis :) Seriously though, I am planning on ordering one. Life is too short for drift aligning. Thanks Eddie Trimarchi ~~~~~~~~~~~~~~~ -----Original Message-----
