New Losmandy polarscope illuminator?
Posted 03 March 2010 - 07:27 AM
Anyone know if it's dimmable (like the Tak illuminators), or does it just have an on/off switch?

I was disappointed that, with the GM-8 anyway, the illuminator is long enough to bump into the mount base. So this means at some times of the year there would be interference getting the star map rotated to the right position. Not that huge a deal, but should have been avoidable by picking a different keychain flashlight design.
Overall it's not a bad solution, but I keep it off the mount most of the time.

I've got an AP600, but it looks like it might hit the altitude adjustment knob when pointed straight down. Still, I only use that mount during the summer, so hopefully it won't be an issue.
My existing illuminator has a flaky connection so it needs to be replaced with something.

I just got a new GM-8 mount with the new illuminator. Tried it last night for the first time. I found the new illuminator was too dim. It didn't light up the reticle enough for me to see it. Anyone else find this is true? Admittedly, this was from my backyard which is not exactly a dark sky site. Perhaps at a truly dark site the reticle would be more visible.

Please look two messages up from yours.

The length of the flashlight body does allow for damage from a good bump so I prefer to have it in place only when actually using it, which for me as a visual non-goto user is not that often. Besides which it looks sort of goofy.
I like it better than any of the wired solutions I've seen so the cost was worth it to me. If I had a more permanent photographic setup I might prefer something else though.

I compared the Losmandy illuminator to two other illuminators that I use with my finder scope and reticle eyepiece and the losmandy is much dimmer. Again TOO DIM.
It will have to go back unless I can find a way of getting it brighter.

I think the new RAPAS finder from A-P is great but it does use what looks like the same Chinese-sourced illuminator that came with a 20mm reticle EP I bought from Orion a while back. While it is one of the better built illuminators I've used the dimmer often doesn't work properly and is almost always too bright (maybe A-P fived this?). If the Pulseguide fits the RAPAS (haven't tried yet), I'm going that route.
A while ago I went through a frustrating search for a replacement polarscope dimmer (for both PASILL and Astrotrac scopes) that lead me to the Pulseguide. You'd think it wouldn't be so tough to design a quality illuminator with a decent pot switch that works....? Well, at least there is the Pulseguide.
BTW, I just checked the specs and the Pulseguide uses 8mm threads but there are 10 and 14mm set-screw adapters available, so maybe it can be made to work on non-standard thread holes?

I'm not sure about the thread size and fit but you might want to consider the Rigel Pulseguide.
There's a variety of such illuminators out for finders and what not unfortunately they won't work on a Losmandy polar scope. GN

I don't, even with bright lights around. Did you click the button 5-6 times to increase the brightness?
I too find the new Losmandy polarscope illuminator TOO DIM.

Contrary to what was answered on the CN forum the new Losmandy polar scope illuminator can be dimmed. In fact it has six different brightness steady on settings and six different pulsing brightness settings.
I will write the actual direction for use on the forum.
Hope this helps!

"When the button is held dow the PSI will sequence through six levels of constant and then six levels of flashing illumination. Releasing the button at any time will maintain that setting for two minutes before automatic shut-off.
To re-activate the PSI, press the button until the LED comes back on and release. The PSI will awaken at the last setting and remain on again for another two minutes. Holding the button down will step through the sequence of increasing intensitites."
The PSI uses one CR2032 coin type lithium battery.
Hope this helps for those of you who are wondering how this new Losmandy product functions.

I applaud the illuminator from Losmandy. It is functional, simple and virtually foolproof (unless you don't read the instructions!). I believe it is priced too high for what we get but I was willing to pay this just to be rid of the older version. (edit: Please understand that the sky is so dark where I live that an illuminator is only necessary when there is a bit of moonlight - on dark sky nights the reticle in the GM-8 polar scope can be seen without any need for an illuminator!)
The other illuminator I bought recently was the one orion uses on their 20mm centering eyepiece. Can't remember where I got it from, but it works pretty well and seems to hold up okay for now. It's the one that has a funnel-shaped section in the middle. I use it with my Meade 9mm to drift align.
I have spent countless hours fiddling and messing with illuminators, trying to get the light to stay on, trying to get the batteries to make contact, etc. This accessory has generally been the most frustrating failure to date of any of my astronomical equipment. And Meade should just quit selling the ones they use with their reticle eyepieces- Just awful.
Buy the Losmandy for your Losmandy polar scope, there aren't any others that fit. All the others are a gamble. Of course there is the Takahashi version for $175

I had to take out the illuminator, turn the polar scope to position then screw illuminator back in. bob
