PEC is the poor man's tracking system. It can't compensate for things that an autoguider can. Things like mirror shift, focuser/camera sag, optical train...
... Most of those can only be handled by an autoguider if you use an off-axis guider rather than a guidescope. And only a dual chip camera can deal with ...
Hey Warp I'm probably not the best guy to answer this.I just got my second DSI. The Meade software can handle both at the same time. You can guide with one if ...
<SNIP> ... It depends where the sag is happening. If it is happening after the off-axis guider then true. If it is after the focuser but before the off-axis...
Your Discovery Store must be different from the one I see on Internet. The only DSI camera is $499 and there are no closeout sales. ... illuminated reticle ...
No internet sales. Only the stores that are closing all over the country. Got mine from the Austin, Texas store. $65, including shipping. ... From: "Gregg"...
... I disagree. Since they are both attempting to command the same motor in every current commercial scope control system I have seen, it can NEVER improve...
... Hi: I have never read a definitive statement about turning PEC off and letting an autoguider do 100% of the correcting during an imaging session. I have...
Speaking specifically to PEC in the Autostar 497, which is similar to most other GOTO systems, PEC is a software subroutine in the Autostar and so is the...
Gday Christopher Just a few interspersed points ... Not quite, they cohabitate. The std LXDs have a PEC period of about 4 clock seconds. Ie, when PEC is ON,...
Well, I had the altitude clutch break on my ETX-125 (old style mounting) and sent it back for repair. I seem to remember it was gone about 2 - 3 weeks,...

A couple more observations for the discussion. PEC training is done with a temporarily closed loop system that might be done entirely by computer or it might...
Can you tell us who you talked too and what store (phone #)? I called several in the Texas area and they said they would not ship and yet you indicated - that...
... However, Meade's implementation of PEC does make it somewhat proactive. During training, you're telling it the error at the -end- of a PEC segment. During...
Gday Chistopher ... I never said it did. In fact i stressed you still need a guider to allow for imperfections in the worm wheel. Sorry to have upset yr day. ...
The Austin store has closed, at least as far as Discovery Store Customer Service rep says. The Austin phone # is now routed to above. Short of cruising any...
Hi guys, I am new to the group. Most of my astro interest is in imaging but I am doing more visual stuff lately. I posted the message below on the SCT group...
I think the 200R's have better contrast and a flatter field but what the heck, that's just an opinion. If this scope is for visual only use, have you...
Hi all! First of all, I would like to say to all of you thank you. Thank you to give me some advices Thank you to help me Thank you to answer to my questions ...
Thanks Christopher. I am considering the 16" Lightbridge as well. In that regard, I am still evaluating the choice of a 12" or 14" sct. I'm not sure there is...
Hey Bill I don't follow what you're saying. You say your past interest has mainly been photographic, but now you want to upgrade ONLY based on visual? I don't ...
Thanks Joe. Sorry to not be clear. I have a house in the mountains with a dedicated roll-off observatory. Skies are about mag 5.5+ on a good night. I have a...
When the R series first came out, there was an article about it in Sky and Telescope. It was a side-by-side comparison of the regular LX200 with the new type...
Maybe not from Discovery stores, but Meade has been closing out the old generation DSI cameras. Many dealers have them for as little as $99, depending on the...
Some posts have indicated that the monochrome version of the DSI (DSI Pro) is a better choice to use as a guider than the Color version. Can anyone confirm...
Can't comment on the autofocus as I don't use one... The cameras: The basic difference between the mono and colour is that the mono camera uses the entire ccd...
