Meade LX90 Advice

Hi again,
Acquired a Meade LX90 UHTC 8" F10 with heavy field tripod and autostar with a full set of series 5000 eyepieces some still in plastic for what I believe was the bargain price of $500 everything seems to work fine optics are pristine.

What would be a first good upgrade for the setup considering everything is stock, diagonal / spotting scope ect

would you go for a focal reducer first or upgrade the diagonal to a 2", interested to hear opinions, at the moment I will just be doing some casual observing, planets some DSO's hopefully.

TIA Gordo.

You got the scope AND the eyepieces for $500??? Or just the eyepieces? Either way, not a bad score.

Maybe just get familiar with the scope before accessorizing too much (I understand the temptation), although a decent narrowband filter will help you in your search for nebular DSOs.

You definitely picked up a bargain!

If you’re thinking of taking it to dark sky sites, consider a good external power supply.
A dew shield and possibly heaters are almost essential, depending on your location.

A great buy Gordon! Congratulations!

Regarding your query, I would add a GSO 2" quartz diagonal as a first upgrade. I found with both my Celestron CPC and a friend's LX90 that the star images immediately improved from fuzzy to text-book with the new diagonal.

I would wait until you have used it for a while before deciding on a focal reducer.

All the best, and happy observing!

Dean

Hi Gordo

As others have said great buy!

The best thing I think I have done for my LX90 is a red dot finder.

Makes getting the guide star into the finder scope much easier for alignment.

And you will probably need at least a dew shield, and probably heater. If nothing else, the dew shield helps keep out stray light.

Hi

I think the Telrads are good units, but, I REALLY don't like the look of them.

I went for this style, but, don't really remember where I actually bought it from. I think it was Bintel while they were still in Melbourne.

From memory, I think you need to be careful what 2” diagonal you choose, as some can be too long to fit under the base when the scope is near zenith. Otherwise a good choice.

Hi

I can testify that Brian is right. With my 2" diagonal, no zenith.

Depends on your budget. I have found the Meade 5000 series enhanced dielectric diagonal has worked well on my LX200 8". The Baader diagonals can be very nice and very expensive. I would check ebay and sometimes even places like Agena Astro in the US that have a good range and shipping cost is pretty good.

Bintel have a couple although their range is a lot smaller than I recall - https://www.bintel.com.au/product-ca...her/diagonals/

Or you could watch the accessories section of the classifieds as diagonals do come up from time to time (or put a wanted ad up). Sometimes a well cared for secondhand diagonal does just as well with the bonus of cheaper cost.
