SGL is back online :)

Apparently 1000's of websites were affected. The data center is currently running from generator power so there is a chance of further downtime throughout the day.

Stargazerslounge down due to fire!

The Stargazerslounge astronomy forum is currently down due to a fire at the data centre. Coincidentally their sponsor's website First Light Optics is also down. (They are hosted on a different server but based at the same data centre). There are backups for both sites so they are safe. I will update...

Please get in touch Brian, we don't have your order on our system :? :?:

The Celestron C80 ED are in stock, delivery is overnight via Fedex so the postal strikes are not a problem.

Dielectric coatings were first developed for the US Army for mirrors used in desert warfare and muddy water so you should have no difficulties cleaning your diagonal, just use whatever method worked with your regular diagonal.

We're back!

We had a few hiccups but overall the move appears to have gone well.

We are currently working thorough emails, PMs and phone messages and expect to be back up to speed in 2-3 days.

Thank-you for your patience

Steve :)

Sincere apologies for having missed your email. FLO is in excellent health, despite the recession, but I personally went down for a few days with a lurgy, then an Easter break and now the SGL-4 Star Party so we have fallen behind with communications and will probably need a few more days before we a...

Re: Got my heart set on one of these...

I have my heart set on one of these... The argument for a truss-tube Dobsonian (portability) becomes stronger as the aperture size increases. A regular 8-inch solid-tube Dobsonian telescope will fit nicely across the back-seat of most cars with the base in the back. So, unless you really need porta...

Someone once showed me how to tell whether your home-made red-light torch actually is 'red'. If you project it off the shiny side of a CD then view the reflection, you should be able to see only red light. If you can see other colours in the reflection then it might affect your night vision. I am no...

7mm might be acceptable if you are you are young...but impossible to achieve if you are old ... And impossible to achieve in daylight... True, but there is one advantage to having a 7mm exit-pupil that benefits even us middle-aged astronomers with eye pupils that cannot achieve 7mm: It is easier to...

Hi William, We're back :-) We had a problem with our server recently which meant we had to go offline for a while. We are now safely installed on a new server with a shiny new helpdesk (our original one was damaged!). http://stargazerslounge.com/index.php/topic,37688.0.html Anyhow, we have found you...

I do think it'd be a good thing if telescope manufacturers made more use of aspheric lens elements. Aspheric elements can be used to increase optical performance and/or reduce the size of the optic. Aspherics are now routinely used in photo optics but other than the Celestron Omni XLT 120 and 102 th...
