you could still play with the PST. Maybe the one you have is the one I used to have

Mine was sent to Meade to repair work.  I will start to use it now that the house is about all done.  All my free time has gone into fixing the house so the county won't take it away.

good thing they saved you from dying in a fire trap.  

 

cardboard is not allowed as a replacement for drywall in homes for wall finishes. While cardboard can be used for temporary patching or certain construction purposes, it is not a structurally sound or fire-safe alternative to drywall, according to InterNACHI®️ Forum and YouTube. Drywall is specifically designed to provide fire resistance, structural support, and a smooth finish for interior walls, whereas cardboard is more prone to damage and doesn't offer the same level of protection.
Why cardboard is not suitable:
Fire Safety:
Cardboard is highly flammable and doesn't offer the fire-retardant properties of gypsum-based drywall, according to Zehnder Clean Air Solutions and tytan.com.
Structural Integrity:
Cardboard is not strong enough to support wall loads or provide the necessary structural integrity for walls.
Moisture Resistance:
Cardboard is susceptible to moisture damage and can warp or deteriorate when exposed to humidity or water, 
Pest Resistance:
Cardboard can attract pests like termites, which are attracted to the cellulose it's made of.
Building Codes:
Building codes generally require the use of fire-resistant materials like drywall for interior wall finishes.
When cardboard might be used:
Temporary Patching:
Cardboard can be used for temporary patching of small holes or gaps in walls, but it's not a permanent solution.
Construction Forms:
Cardboard forms are sometimes used in construction for temporary purposes, like holding concrete in place during pouring, but they are removed before the building is occupied.
Cardboard is commonly used for shipping and packaging items, but it is not intended for use as a wall finish.

I just use it to cover up the studs bud and block walls jamal.  I would have never fixed up the house if the country did not force me.  Cat5 with gust over 200mph coming soon.

F/6 Nix.  No P needed.

 

Let's say a Paracorr was optimized to work at f/4. Then if you stopped the scope down to f/8, you'd still obviously have the same correction or better. So using a CC at f/8 will not cause any damage, other than subtraction and scattering of light because of a lot more glass. I think at f/6 it would start to get interesting.

Ok misread the post. I thought you were getting an F5 my mistake.

I am a one trick pony. Jupiter is about all i care about. All scopes are put away until Sept.

C'mon man you gotta turn your 8" Z onto Omega Centauri. Haul it down to a beach with a southern view. Look due south around 11 PM. Should be about 15 degrees up down there.

 

The most amazing thing I have ever seen in a telescope is Omega in a 10" f/4.5 from up here near Atlanta. You're way better off!

Chas, we still need to make that trip to the Keys for a Messier Marathon…I can still close my eyes and see my first view of Omega Centauri from there…deSitter is right.

 

Did you get your PiFinder to work on the PB?  A Messier Marathon with a clear night and the PiFinder would leave a lot of time after the first hour and before the last hour to catch up on some sleep!

I don't have a PI finder. I got turned off of all DSC's years ago and GO-TO and wires and drives of any kind. The Ball is so easy to use i am gonna sell the AP 900.  I just don't want anything bigger than 8" anymore.  I was heavy into all that jazz with the LX200's around 1997 till around 2003 and the Sky commander.  The ball is a little jerky perky at 450x and up.  I will wax it up next Sept when Jup is back. All my time has been put into the house and i am almost done.  I think it is time to give up and just keep the 110mm Tec by heck and the 8" Ball jamal.  I never really look at deep sky and what i do look at i can find faster than any GO-TO.  It is just a job getting the AP900 over the bumps in the door.
