Daylight saving help - what to do with scope & pc?

rogerg (Roger) · #1 26-10-2008, 07:31 PM

G'day all,

A question for those more experienced with daylight saving than us here in WA.

Daylight Saving started in WA last night. I'm a bit confused about what to do to the clocks/time-zones of my scope and PC software.

I have a LX200 classic and run TheSky6 to control it. Running on XP.

1) XP has automatically adjusted it's clock to the correct time.
2) I have changed TheSky6 to timezone +9 instead of +8, correct?? (it does not have daylight saving settings for WA in its configuration)
3) I have not changed anything on the LX200, do I need to??

I'm a bit confused as to if I need to change TheSky or the LX200. Right now, with the configuration above, It looks like the scope knows it's in the correct place, but I'm not sure if there will be a problem and I needto adjust the timezone and time on the LX200?

Thanks!

Roger.

PS. I can't remember what I did last year!

Roger I adjust nothing daylight saving or not, my Gemini controller has no idea that some one decided to call a certain part of the day by a different time.

I makes no difference at all, as the stars sill rise at the same time as they have always done, and I just go out imaging a bit later.

yes you do have to change them Roger, both the time and time zone.

Why is that Mick, I can't see the point, if I was imaging at 8pm one day before daylight saving began, and then went out the next night, I would just go out at 9pm, the scope and mount don't know any difference, and the stars would still be in the same place.

l see your point Leon. however it doesn't seem to work that way, if l go out after daylight savings starts and do not re-time the scope even though l do a one star alignment and sync when l slew to an object it will be out by the factor of the time difference, adjust the time and re-sync, goto is spot on.

I think (but am not sure) some adjustment is required, so I'm included to agree with Mick, but don't understand fully why.

The reason I think some adjustment is required is because I'm pretty sure I've had odd situations when syncing/goto via PC etc, it gets out of sync by an hour? Go to accuracy goes way off.

Wouldn't it be easier to tell the PC not to use daylight savings. XP does have that option. Saves stuffing around with the scope and mount.

I dont even bother to change it - it will be right in a few months time.

Leaving the PC and LX200 at proper time is an option but it just makes my life a little more complicated so I would choose to have them set at "current time" if easy.

Thanks,
Roger.

Good one Phil, but it is not a problem, well not for me that is, I have never changed anything and when I fire up the mount and tell Gemini to go to the star I have selected, it hits it, daylight saving or not.

I still have to disagree, it makes no difference,

I reckon if one starts to change things, then they are for ever changing things when the occasions arise.

If I changed the times in Gemini by one hour, today, and then fired up the scope, it would miss it's target, for sure.

believe me Leon l have the same scope as Roger and if you do not change the time and daylight savings time setting it will be out when a go-to is instituted. if it made no difference there would be no need for the inbuilt clock in the first place, it would only rely on your star alignment.

Hmmmmm. I will ponder on this Mick.

I ended up configuring both TheSky & the LX200 timezone's by one hour and adjusting the time by an hour on the telescope. This way the scope and TheSky have everything matching up and I am able to set the 'scope's time from TheSky at any time without worrying about messing something up (I do this regularly to keep the telescope's time as accurate as possible).

Thanks,
Roger.
