My f4 hardin (starhoc 8 ota) can do 160x on jupiter, maybe 200x if I get it collimated PERFECTLY, but f5 is more forgiving than f4, so I can see how this is...
Hello to all! I mentioned last month that I had some problems collimating my Coulter 13.1" Dob and was offered advice as to what to do. Turns out that teh...
Wally, If you are not noticing any difference in the views, from a known poorly collimated state to what you are seeing now, perhaps it is because the laser is...
Thank you, Phil, I also have a Nexstar 11 GPS and found the same phenomenon. If is is a bit out of collimation DSOs look the same as when it is collimated....
Wally, I also have an SCT. A C8. It, like the C11 is F/10. It is not nearly as sensitive to collimation errors as my F4.5 and F/5 Newts. I know what you mean...

Phil, I disagree about which instrument is more sensitive to mis-collimation. The secondary in a typical SCT magnifies 5 times and so the errors are...

Wally, I did some reading after seeing your note. It seems that many tend do agree with you that SCT collimation is critical (though not necessarily *more* ...

Well after cleaning some lenses and adjusting mirrors on my new used 4420 telescope, I took it out last night to have a look at the moon and what I believe is...
Sounds like you had a great time. With that scope you'll have many more. A barlow and maybe a 12.5mm eyepiece might give some great performance. Don't ...
Well I made my first attempts at digital astrophotography last night with the almost full moon. See "Edwin's Pictures" album in the photos section. It took 8...
Hi guys, IS it feasible to use a focal reducer with an F5 Newtonian. I have one I could borrow, so I might just try it, but at 0.5, it would give me F2.5 -...
HI Tom, F/5 is pretty fast for a newtonian. I would be happy with that. I am using an F/7. There are unfortunately no focal reducers I am aware of that are a...
Yes, and coma is bound to be a bigger problem as well. It did occur to me that while F2.5 is probably not practical, it might be possible for me to combine a...

Yes, I have seen some amazing shots with that little scope. I was thinking of trying the focal reducer anyway. But I probably won't. It's an awful lot of...

Those Stellafane pics are superb but for me the piece de resistance is the 12.5 inch Split ring mount Newtonian. I first saw this design when Joe Porter...
