Hi All,

I've acquired a Skywatcher Heritage 130p second hand and would like to get a barlow that can be used with this scope as well as my future purchase, which is most likely to be a 10" Dob, probably of the Skywatcher FlexTube variety.

I understand that the little dob doesn't have much in-focus travel and hence probably need a shorty barlow for this one, which may not necessarily work in the 10" dob. For using the 15mm Bintel/GSO SuperView eyepiece I have had to shorten the focal length of the scope by about 1cm using the storage rods to allow me to focus on astronomical objects.. Interestingly it can focus just fine on terrestrial objects that are several hundred meters away without requiring adjustment to the storage rods.

I am having to return the Bintel/GSO 15mm to Bintel this week due to particles trapped inside the eyepiece, so would appreciate if anyone knows if the standard TeleVue 1.25" Barlow or the Bintel/GSO 1.25" Barlow in either 2x or approximate 1.5x mode will work with the little SW 130?

Eyepieces I currently have are:
25mm Super (inc with 130p)
10mm Super (inc with 130p)
15mm Bintel/GSO SuperView
6.7mm Explore Scientific 82deg

Thanks in advance
