hi,

I am unable to wind in the focus on my skywatcher 200 to achieve focus when a standard barlow is between tube and camera.  I am seeking recommendations on a shorter version Barlow (with t ring) so that I can gain focus on Jupiter, Saturn on the camera. As far as I can see it would appear that longer barlows are around 5-6 inches and the shorter units are 2-3 inches. This reduced length would likely deliver the space I need to gain a focus.

Appreciate any advice on others who've no doubt overcome this issue. 

Neil

Does your telescope have a 2"/1.25" Crayford focuser ?

I have the standard focuser on the 200P. The 200 PDS comes with the low profile unit.

An upgrade to the low profile Crayford is an option, however, a little pricier.

      This is NGC3603 and NGC3576 (AKA The "Statue of Liberty" nebula), a massive H-Alpha region containing a very compact open cluster, located in the constellation "Carina" about 20,000LY away.
      I took this photo during two nights, 14th and 15th March 2021. Imaged using a active cooled and full spectrum modded Canon 40D DSLR attached to a 80mm f6.25 refractor on a CGEM equatorial mount.
      Total exposure time was 3 Hours and 31 minutes in natural color through UV/IR Cut filtered subs from a semi rural sky.
      RGB: 19x60s, 19x120s, 18x180s and 20x300s subs @ ISO1600.
