... I had seen that, but I was holding off installing it in the hope that the Sky's standard driver could be made to work. Plus I wasn't quite sure what had to...
... Ascom drivers will not interfer with Thesky's native ones. See http://ascom-standards.org for installation and other details. I also have an installer...
I read the review right after getting the magazine out of the mailbox. I found it strange that the reviewer didn't even mention the FSQ while comparing the...
Hi Rick, I have an NP101 and an E160 and I agree that the compression ring geometry of the Tak is far superior to that of TV. The Tak is more like a true...
Thanks for the report. Sounds like a great filter. Coronado used to be located on the Ilse of Man, where Solarview is made, didn't they? I've seen that...
Hi, I am contemplating getting a Mewlon 300. It would be a much better fit in my observatory than a large apo. refractor. However, the 29% central obsruction...
I have no idea where that 20% obstruction thing comes from, but it's simply not true. I have a theory, and it goes like this: * A few decades ago, there were...
Hi All, Does anyone know the current availiability of the FSQ-106? I have been told by a local retailer that they are not available until the first of June...
Hi Mark, I am no optical expert but I think the argument that a CO over 20% causes material damage to planetary performance is generally overstated. Here is my...

Marc, I'm a long-time planetary observer and imager. I have used (and still own) a 6-inch f/12 achromat (glass made for NASA) of outstanding quality, a Cave,...
I have an opportunity to buy a TOA and need to raise some funds to do it I have a pristine perfect FCT-76 system with helical focus for sale I have all the...
Hi B you buying another TOA, Guess the withdrawal symptoms setting in lol. Its the best scope ive ever used also. Rich [Non-text portions of this message have...
Good day to all, I am new to the group and will probably post regularly, as I am now buying an Tak FS128 (can't wait!!!!). I recently purchased a Takahashi...
I've seen an observable difference between a Takahashi TSC 225 (belonging to me) and an Astro-Physics 180mm f/9 refractor. It was a subtle difference that many...
Mark, The CO of the Mewlon will diminish contrast to the extent that it is detectable, compared to a comparable scope of same aperture. Comparing a 300mm...
Richard, I have one, it's a 40mm filter (module) that screws into the draw- tube. The module is threaded on the back end, and all Tak accessories can be...
... Ahem, Actually I just verified that Abberator does show the effects of varying central obstruction on the MTF plot (contrast) and the PSF/EE (similar to...
Robin, ... All of this makes perfect sense. The Tak did not have enough aperture advantage to overcome the unobstructed optics of the refractor. ... What was...
Hi Bill, You wrote "-I guess besides fitting in his observatory Mark has to worry about availability. As far as I know the only APOs available (except used) ...

I think the key is not to get to carried away with the effects of CO. It has an effect (has too unless the laws of physics go away), but the key factor is...
