Please forgive me if i'm missing something very obvious, but isn't the mount supposed to take the weight? and to do an exact polar alignment its best to have all the gear on and balanced beforehand
I always thought - and I could be wrong that the mount will disperse the weight of your scope, with some of it going to the bolts.
If you try to adjust the altitude under load the bolts will have to adjust the full weight and will be at risk of damage.
Thats why I never adjust my mounts loaded.

Hi David
Thanks?. I hope mine will be with me for as long as yours has been with you. I just can't wait to have a proper session with it.
I plan to keep the original focuser but will probably get a baader helical micro focuser to give that extra precision at very high powers.. I've used one before and they are very good. How high do you go with yours on very steady nights?
Dave
Hello Dave,
Just checked and my FS128 was made in 1997 - 20 years old and still going strong
Generally I use mine for the planets, typical observing powers are :
Jupiter : x148 to x225
Saturn : x173 to x235
Mars : x238 to x297

Hello Dave,
Only just found this thread....
Welcome to the FS128 club
MIne was made a year before yours and has given me 9 years of great views. I have replaced the original focuser with a Feathertouch which is a perfect match for the quality of the OTA.
Have fun with it - and never sell it.
Here is mine in action......

Thanks, it's good to hear from someone who has had both. In what ways was the 100ED better specifically? And do you feel it was £300 better?
Because the ED100 was easier to cool and could keep up with dropping temperatures through the night it gave sharper and more stable images quicker than the 127 Mak.
The clear aperture of the 127 Mak is actually 120mm, which means the 46mm secondary gives a 38% obstruction - this reduces planetary contrast to about the same as a 2.9" refractor, so a 100ED will have more contrast - vital on the planets IMO.
I have also compared the ED100 to my Takahashi TSA102. The ED100 gave embarrassingly close planetary views to the TSA102 !!!!
In my opinion the ED100 is superb value for money.

I've had both the scopes you mention.
The 100ED was the better of the two scopes on all the objects you mention and cooled down quicker than the Skymax 127.

How about sending the mirror to Orion Optics, asking them to re-figure it to 1/8th wave and then have them resilver and recoat it ?

Very nice APM152 Adam - that scope is on my wishlist.......

There's a 1/10th wave Orion Optics 10" dob on ukastrobuysell at the moment.....
I have no affiliation with the seller

I have two 26mm Celestron silvertops as in the photo above. Thay are used as a bino pair and are excellent.
I bought the first in 1986 and added the second a month ago.
Well recommended.

I have a Takahashi 102 and a 128 - the 128 shows much more planetary detail then the 102.
Had a Mewlon 210 but wasn't impressed when I put it up against the 128.
Olly has thrown a 140 into the equation - definitely worth considering.
As Peter says - aperture rules - A good 10" Newt will beat all of the above.

Thanks /p, it's definitely not metric, it could be UNF 8-32. It would be great if someone could confirm that .....
-
I would like to change the standard 6x30 finder bracket on my C8 to a Synta type shoe but need replacement screws.
I thought the screws were UNC 8-32 but I bought some of these and they do not fit.
Does anyone know what the size of these screws are please ???

Good thread this .... but the original poll suggests the answer to the OP's question is an 8" Newt. My experience despite owning a very good 5" Flourite APO backs that up.

To give you peace of mind I have purchased a lot of Astro gear from FLO and received excellent service. I only ever had one issue which FLO dealt with to my complete satisfaction.
Es Reid cleaned, collimated and star tested my 5” Takahashi - I was delighted with the results and his professional approach
