Optical Tube Assembly
The new Skywatcher Explorer-250P DS has the same superb parabolic primary mirror as the original Explorer-250P but features a 1.25"/2" Dual-Speed 10:1 ratio focuser for enhanced focus control and a shorter tube length with the secondary mirror positioned closer to the primary mirror for more convenient prime-focus photography.
The Sky-Watcher Coma Corrector is also available for astro-photography.
Specification
This thing is a light bucket, I had been doing some astrophotography temporarily using a skywatcher 50ED when I realised that the Celestron 130EQ doesnt have the range of focus to work with a camera, I had some minor success with long exposures to get some detail of the Orion nebula.My first attempt with the 250PDS & guiding I didnt really know what I was doing and I thought I had a number of 2 minute long exposures, I turns out I messed it right up and what I had was a bunch of 1 second exposures. Those 1 second exposures showed a lot more detail than anything else I had been able to get just due to the amount of light it collects.It is a big heavy monster to move around but with the image quality I am getting I dont mind.The construction is solid but the instructions that come with it are totally useless & I havent tried the finder scope that comes with it as I have a 50ED.Very pleased with the scope and the service from FLO
Great service and speedy delivery from FLO, I haven't used the scope yet as I am making a Dob mount for it but it looks a great piece of kit, and I cant wait until its up and running.
