Grant and Paul,
Its a Paramount MX with a 70 star T point model.
I use http://www.thinkman.com/dimension4/default.htm to set the clock.
Question for Grant: Are you saying that if I change my lat lon location in TheSkyX I have to do another T point run?
Regards,
Jack

[Mr Jack Martin]

Grant,
I can’t see your post?
Regards,
Jack

A conundrum Google Earth says 51.59 36 0.60 77 The SkyX X says 51.37 45 0.36 27.
Question: If TheSkyX co ordinates are wrong would that explain why the target is not dead centre in the field of view.
It has a T point model.
Which one is correct?
Jack

[Mr Jack Martin]

Awesome spectrum Bill.
What software do you use to reduce it?
Regards,
Jack

[Mr Jack Martin]

All,
THANK YOU for your inputs I will use Google Earth.
Jack

[Mr Jack Martin]

All, I have acquired a Rainbow Optics star spectroscope its primarily to view the spectra of bright stars and general observing no imaging.

Sheridan,
A later version 10.2.0 or newer SkyX software needs to be installed this works with Windows 7 or 10.

Andy and Robin,
I have 2 slits and slot supports and changed from the 35 to the 23 micron slit.

It appears the latter is faulty.

Question, Would the wide slits be useful?

Peter and William,
Because the computer was displaying a black background, I could not see the text in the status bar.
So, in Personalisation settings change to a standard Microsoft picture.
All working.
Thanks for you help.
Jack

[Mr Jack Martin]

William,
I have installed the Ascom platform.

Jack

[Mr Jack Martin]

William,
Thanks for the pointers I am installing on a ‘new’ Windows 10 system.

Peter and William,
I should have explained I am installing Maxim on a new computer.
I followed your instructions but don’t see any numbers or i value?
Thanks for your inputs,
Jack

[Mr Jack Martin]

Peter,
Thanks for your input.

Robin,
‘I recall you have a remote adjustment, could this have been preloading it causing premature wear’?

Are you advising against motorising the micrometer ?

Regards,
Jack

[Mr Jack Martin]

Robin,
I have released the collar. When tightened then slackened a fraction of a turn the micrometer is easier to turn.
It may be worth an overhaul as you suggest.
Thanks for your advices,
Jack

[Mr Jack Martin]

Robin,
It became increasingly tight over time.
From your photos and comparing with the other Lhires the collar looks engaged.
I will overhaul it as you suggest.
Question 1; What lubricant should be used and is there a risk of it getting on the grating?
The remote adjustment is the motorised collimating lens.
Regards,
Jack

[Mr Jack Martin]

Robin,
I loosened the grub screw but can’t turn the locking collar.
Regards,
Jack

[Mr Jack Martin]

Robin,
Thanks for the photos.
I will have another go at removing the grub screw.
I have another Lhires could swap micrometer shafts see if that works.
Regards,
Jack

[Mr Jack Martin]

Robin,
I can’t loosen the tiny crosshead grub screw which must be very tight.
Is there a particular type of screwdriver or extractor?
Regards,
Jack
