Recently, I've had the pleasure to enjoy a couple of neat ED doublets; A William Optics Megrez 110ED F/5.95 and a Sky-Watcher ED120 f/7.5. While the...
Since I've been using the WO Megrez 110ED, it's always had a TV Powermate 2.5x amplifier in the optical train. This results in 1637mm effective focal length...
clive ... out of curisiosity, what is the optical difference between the two barlows, other than magnification? thanks. -- michael On Thu, May 1, 2008 at 12:13...
Thanks Clive for that detailed report! I'm considering trying a 2x ED 2" Barlow of GSO manufacture on my M110 for imaging. The field of view is so big that my...
Hi Michael. The Powermate is a specialized Barlow, known as a "telecentric" type. It uses 4 lens elements (two groups of 2) and maintains the ocular's original...
Cheers, Sander. It'll be interesting to see how the Barlow affects the off-axis image for photography. Let us know the result. Thanks again! C. ... ED 2" ... ...
Hello, I am having problem adjusting my 66SD focuser. It is either to tight or to loose, If I barely loosen the under screw and turn the knob it doesn't seems...
Hi, first adventures with this combination weren't very encouraging. Here is a flat frame I just took: http://gallery.tungstentech.com/main.php?g2_itemId=617 I...
Sander, Why are you trying to use the Baader MPCC on a refractor? It is intended to correct comma on fast Newtonians. It is not intended to flatten the field...
Greg, it was suggested I try the MPCC instead of the FR-III which wasn't all the satisfactory. I'll admit I was surprised it was supposed to work but I'm no...
Sander, You should give the Televue Flattener/Reducer a try, it works great on the FLT132 and the Orion 80ED. Just get the one that matches the focal length of...
Matt, yes, I'm aware of the TV flatteners. In fact I talked to Mr Nagler himself at NEIAC about them. Unfortunately we couldn't narrow it down to a specific...
Renaud, On the underside of the focuser is a round "nut" with an allen key hole in the middle. Simply 1-rack the focuser out all the way. 2-loosen the nut as...
Read the "2-speed Microfocuser Retrofit.pdf" in the files section, to make sure you are adjusting the right screws properly. If you still have problems, email...
Hello All, Actually i am using an WO 80/480 Refractor. It is the Lomo Triplet. I am very happy with it and i will keep it. I want to complete my setup with a...
Hi, I'm using the Televue .8x reducer/flattener with the FLT132 and the ST2000XM. That puts the FLT132 at about 740mm and produces a nice flat field for the...
Thanks for your answer Matt. What model is the Televue focal reducer ? The TRF-2008 ? Georges http://www.photons.fr ... ST2000XM. That puts the FLT132 at about...
Thomas M. Back in one of his last forum posts reminded us that what is most important is being out under the night skies with whatever scope we have. I agree....
Matt Which Televue .8X reducer/flattener are you using. The one for the TV85 or the one for the 102 doublet? Also why are there four spikes on your bright...
Hi Georges, They make two. The TRF-2008 is for scopes with focal lengths from 500mm~700mm, I use this one with the Orion 80ED. The second is the REF-3007 for...
Hi Scott, The one for the 102, REF-3007 for 800~1000mm telescopes. I added the spikes to the brighter stars in post using the Carboni Photoshop actions to make...
Hi Matt, which T-ring extensions do you use? I have some rings from edmund optics and they're fine but are not knurled so they can be difficult to remove. I...
Hi Sander, With the ST2000XM & CFW8a I was right at 50mm from the chip. So I used a very narrow spacer that came with the MPCC that I have and that spaced it...
Hi Matt, thanks. I've only done visual inspection of my images so far to judge correction/coma in the corners. I'll have to give the AIP tool a try too. For my...
Thanks for the information. Scott Walker ... From: Matt Taylor To: William-Optics@yahoogroups.com Sent: Friday, May 02, 2008 11:23 AM Subject: Re: [William...
Yes it does, I just double checked. It says 500~700mm. I also saw the website says 400~600mm. No idea which is correct, maybe both? I do have a Series 5000...
Thanks Garry and Dan, That was easy, it is now working perfectly... I was surprised that such a quality oriented company would make this focuser so unusable......
When I got my M110 with diagonal and UWAN package the focuser couldn't hold its position when aimed at the zenith either. I don't think the focusers get...
