Up until now I was learning the sky using Fujinon 7x50 FMT SX binoculars.
Then I decided to up magnification a little and got
9x63 Celestron Ultima ones - what a disappointment:
- no individual adjustments like on Fuji - as I prefer not to wear glasses,

Some of my more offen used EP's are starting to get a bit in need of clean
ups, what with fingers, ladys eyelash's,etc. I've notice a bit of film
starting to show up. In the past what little I needed to do I used camera
lens wipes for it, mostly dust. But I'm thinking of distilled ...

Trying to decide between a 1.25" focuser or a 2" for my 8" f/6 dob.  Price
is a concern, but hopefully, someday I'll be able to afford a Nagler or 2.
Right now, all I have are 1.25" plossls.
Don't most Naglers work in a 1.25" or a 2" focuser?  Is there any downside

Curious as to how the scopetronix digital camera adapters handle the various
EP relief distances between different EPs.
Or is this taken up in the focusing.

Last night while observing the moon my youngest daughter who is 13 came out
to have a peek, she asked if there was anything to look at other than the
moon. I asked her if she would like to see a double star in the big dippers

I am in the process of putting together a digital slideshow comprised
of h-alpha images of the Sun that I have taken and simulated images to
scale of other stars.  The simulated images are being made from solar
images I have taken that are scaled up or down as appropriate and

Can anyone recomend  good lnar atlas and observing guidebook?  I know Rukyl
is supposed to be the best, but its out of print & I can;t afford it at the
prices its going for.  Whats the next best atlas?  What is a good
guidebook, that lists things to look at, and describes their ...

Good day,
I am after some thoughts on star diagonals for a C11 SCT.
The included piece has begun to deteriorate after only three years, and I
suspect it was always the weak link in the chain anyway.  Given these

Hi Gang,

Has anyone played with one

I am considering the construction of my own 10" Newtonian/Dobsonian
telescope. Do any of you have any experience with or knowledge of the
following kits? If yes, would you send your opinions? Recommendations on
other kits would also be appreciated.

As a newcomer to the hobby I have recently purchased a celstron 114GT.
It arrived with 2 eye pieces 10mm and 25mm.
Iam thinking of buying a 4mm would this be alright for this  4.5" telescope?
Many Thanks,
