I received my Moonlite CFL 2.5 focuser today. It was really easy to change out the stock focuser on the sw 150 ed. Four screws and you are done! The Moonlite sure looks good. Can't wait to try it out. However, I did notice that the Moonlite does not extend out as far as the stock focuser. I will probably have to get an extension.

This depends on how long the draw tube is on the ML compared to the OEM.  It might be shorter in overall length, but just as long once extended.

More info focusing on a distant tree: With a 24mm eyepiece (orion stratus) there is only about 1/4 of an inch of back travel left. With a 8mm ep (orion stratus) it comes to focus, but the draw tube is fully extended. The Moonlite comes with a 1.25 inch extender. Do you think changing it out with a 2.5 inch extender will be enough or not enough?

Try the extender it comes with before spending more on something you may not need.

If you find you need more back travel for 2" eyepieces there are cheap extenders available.-

Been wanting to change out my focucer, but couldn't find a frange on the web site. Which one did you use?

Just let Moonlite know your scope.

 

Before purchasing, you should check the focuser range of all of your eyepieces and barlows, then order the appropriate draw-tube length.

Moonlite has a large list of flanges on their page. However, my scope-the Evostar 150mm ed was not listed. I contacted Moonlite and within an hour Mr. Ron Newman got back to me and told me which flange to order for my scope. For the CFL 2.5 focuser I ordered there was only the 4.5 inch drawtube. The Moonlite is a nice piece of equipment. I know you will enjoy using it!

I don't see CA in my SW150ED. Try better eyepiece like TeleVue and ES also good diagonal.

I notice you have the SW 150ED and the Orion 180MM Mak-Cass. Ever do a shot out on planets? Which is better on planets?

Not yet! Jupiter and Saturn were so low now. I will do that next year! I did look at Jupiter and Saturn few months ago in my SW150 and I like it very much! Sharp and good details on good night and I use ES 100 degree 5.5mm eyepiece for 218X.

 

SW150 is big compare to 180mm Mak Cass but 180mm MakCass require much longer time to cooling time and its not good for get up early and grab it to look at stars also I remember that Planets look little soft at high power. That's why I want to test SW150 and Orion 180 Mak Cass next year but I will keep my SW150 for sure because its wonderful from low power up to around 250 power. Open Clusters and double stars is great in my SW150.... sharp pinpoint stars!

I obtained the 2.5 inch extender from Moonlite and stacked it onto the 1.25 inch that comes with the CFL 2.5 focuser. I haven't been able to try this combo yet, but the length of the focuser is now the same as that of the original. I am now in the process of swapping out the dovetail and rings as the ones provided by Sky-Watcher seem to be weak for such a long and heavy scope. More later!

I received the Parallax rings and Losmandy DUP14 plate today and got them installed. I think this will conclude my upgrades to the scope. The Moonlite focuser is very smooth with 360 degrees of rotation. Here are some pics of the upgrades.

Sky Watcher sales a version of this scope with an upgraded focuser and dovetail/rings combo already installed. Its called the DX model. The reason I didn't purchase this version is because I could find no information on the focuser they used. I didn't want to invest several hundred dollars more only to have to replace the focuser. You can't go wrong with Moonlite. The dovetail and rings for the DX model can be purchased separately, but not in the US at this time. At least this is what Sky Watcher told me when I asked.  

 

For those of you who own the 150mm ed Evostar scope and want to up-grade the dovetail and rings here are the parts I used. The team at High Point Scientific helped me out and were great to work with. The dovetail plate is the Losmandy 14" Universal Dovetail Plate for Refractors - DUP14. This plate is one inch longer than the original dovetail, which I like. The cost is $85.00 US. The rings are from Parallax and can also be purchased from High Point Scientific: Parallax Standard Tube Rings for 155mm (6.10") OD Tubes (Tak FS-152/TOA-130) - SR-155MM with a cost of $195.00 US. The rings have to be ordered as they are drilled and tapped to fit the plate you have so expect a two or three week turn-around time. They are well worth the wait!

One can also buy the upgraded Sky-Watcher rings and dovetail plate from First Light Optics in the U.K.  F.L.O. is easy and safe to deal with.

With the Moonlite focuser, Losmandy dovetail plate and the Parallax rings, you now have a scope that is the equivalent of the APM version in terms of optics, and mechanics (with the exception of the sliding dew shield and depending on one's taste, fit and finish, which IMO is better on the APM OTA and case).

 

I might also mention that with your upgrades, your SW 152 ED is also the equivalent of the APM in terms of price.

 

You now have a fine telescope for every type of observation that we amateurs are fond of pursuing and I hope you enjoy it for a very long time.

My only quibble is optical equivalence between the APM 152ED and the SW 150ED.  Did I miss the side-by-side comparisons by experienced observers?  Some Jupiter / Saturn imagery from the SW with notes on location, seeing, equipment, etc. are also needed in lieu of / supplementing SxS reports.

 

I'm not saying the SW is optically inferior or superior, I'd just like some objective reports.

 

(If you check my older posts, I've been a cheerleader for the SW 150 from the get-go.  We need multiple makers & vendors for these Big EDs -- competition benefits everyone.)

The 150ED was briefly on sale for AU$2000 recently - too hard to resist. I bought the basic version and added some parts from the spares drawer including a wide dovetail, handle and Baader 4-in-1 visual back.

 

The vixen dovetail is too weak too hold the scope steady when focusing, at least with the short vixen saddle I was using.

 

I haven't had it out in good conditions yet but collimation and optical quality look good.

Yes, my assumption of optical equivalence between the SW and the APM is founded mainly on the good reviews of the SW 100 and 120 ED's, although there have been some posts praising the optics of the SW 150 ED.  

 

I hope my point was not missed by those wishing to obtain a 6" ED for visual observing at a low price.  IOW, if you buy the SW use it as is and you will have saved yourself a few hundred bucks and have an excellent visual scope for the money.  But if you intend to upgrade the focuser (never mind the dovetail and rings) to APM quality, then buy the APM and get the sliding dew shield, more robust case and better fit and finish in addition.

The SW-150 looks awesome in Black. That's a great photo.

I have the 120ED and considered the SW150ED, but I wont fit across the back seat of my car, so I bought the APM 152 with the sliding dew shield ( Which I dont like but accept it as is ) and the 3.7" focuser. They are incredible instruments at any price. But under $3K is just excellent.

Or, if you don't want a sliding dew shield and plan to go with a Moonlite and parallax rings on any scope you purchase, buy the SW and change out parts all you want and get better fit and finish in addition. After all, it is a personal choice.

Thanks Tyson, could be a little while before I get to use it properly as the weather hasn't been kind. Tonight is looking clear but the Sharpstar is going out to finish a previous imaging project.

 

Fairly soon I'll have the AZ-EQ5 organised for imaging with the Sharpstar and the bigger mount will be free for the 150ED.

 

I'm getting bits and pieces together to sit the AZ-EQ6 on top of a Vixen half-pillar and Planet tripod - should be stable for the 150ED.

It's a mild steel, powder coated trailer grab handle I picked up off ebay. It does a fine job but If it hadn't already been in the drawer I would have bought one of these: https://williamoptic...le-bar-patented

(a cheap pedestal drill and DeWalt Pilot Point drill bits come in handy for drilling new holes in dovetail bars)

I thought about buying the SW, and doing the SxS comparisons myself, then keeping the one I found most preferable.  But... that's an expensive experiment -- especially if I had to greatly discount the loser to sell it.  (I hate using "loser" to describe either of these Big EDs.  When they perform at even average for a refractor, they're both good deals for their aperture, capabilities, and - yes - prices.)  In that scenario, it would be to my financial advantage to say both models are Outstanding, but I can't use two nearly identical Outstanding EDs -- but I definitely wouldn't do that -- even to save some bucks.

 

Anywho, IIRC, at least one CNer has performed a SxS, but I'm not sure if it was the current (corrected lens cell) version of the APM 152.  Which reminds me of this point...

 

Buyers of either brand:  If something doesn't look right, don't just accept it as the price for going economy rather than premium.  Unsure about defect vs. the kinds of things that can happen shipping a heavy lens around the world?  Ask the Forum!
