Question on the Pan 41mm.

Posted By Randy Roy
Hi John,

I had the 41mm Pan and really liked it for my Nexstar 11 (F10) and TOA130 (F7.7) and before that my FS128 (F8). It was not useful for my F4.3 dob. I think it is a great eyepiece but would not consider it for anything less than about F7 personally. Also, take a look at the Paragon 40mm. It gives pretty much the same optical quality as the 41 Pan or a lot less money. I am a Televue eyepiece bigot and do not make this claim lightly.

BTW--I had the Nagler 31 and while it is a beautiful performer, the weight and balance issues were too much for me. I now have the 35 Panoptic and love it in my F10 and F6 scopes.

Best wishes,

My Scope

Posted By Randy Roy
My wife and I just built a new house and I am fortunate to have a nice observing deck with lots of decent sky (when it's not cloudy smile ). Here is my CPC9.25. I also have a new Starmaster 10" Hybrid.

Should all telescopes be gold?

Posted By Randy Roy
I'm no physicist, but black body radiation really doesn't have anything to do with the color black, does it?

I like white telescopes, too.

FYI there is a Dobsonian Forum

Posted By Randy Roy
Yeah, but I heard it was run by one of those "Obsession-compulsive" types. That can be intimidating for those of us who've "Mastered the Stars."

Dave,

This is definitely a keeper scope. It may be the ultimate in quality and portability for a dob.

Parracor effect?

Posted By Randy Roy
It will increase it by a factor of 15% making it an F4.95

Just how big are those Deep Sky Objects?

Posted By Randy Roy
Peter,

Thanks for a most useful piece of work! I hope you don't mind if I include this image in with a talk I am giving later this year to my local Astronomical Society on "Astronomical Scale". Is there any chance that you have a higher res image available that could be emailed?

dob to a cpc

Posted By Randy Roy
I love my CPC9.25 and personally prefer it over the C11's and NS11GPS I've owned, but I also have a 10" Starmaster with a ZOC mirror. The Starmaster is a big leap ahead of the CPC9.25 (or any C11 I have owned) optically and I reserve it for the nights at dark sites when I want to indulge myself observing planets and DSOs.

The CPC, OTOH, makes a great second scope. I keep in on wheely bars and roll it out for quick peeks and it is a crowd pleaser at public events. But it comes in a distant second to the dob.

If you can keep the dob, go for the CPC9.25. It is an incredible deal. If you can only have one scope, you will probably be disappointed visually in the SCT.

Just my opinion.

Using a reducer/corrector with my 9.25" SCT

Posted By Randy Roy
I use the new Antares reducer. It is pretty much identical to the Celestron. I use a shorty 2" visual back and a shorty diagonal and it brings all my TV eyepieces to focus easily. It has about 41mm clear aperture and the vignetting with my 35mm Panoptic is only slightly noticeable as a fuzzy ring around the very last degree or so of the edge of field. I've measure via star drift the field at 1.4°. You can get 1.12° without a reducer using a 41 Pan or 55 plossl, so the extra field is worth it on a few large objects. All in all, I would agree with the others and spend my money on a good eyepiece with a 46mm field stop.
