Description/Uses:
- Set of four fixed length and one adjustable length M48x0.75 thread extension rings/barrel spacers
- Fixed length spacers: 5mm, 10mm, 20mm and 30mm
- Variable spacer can provide 0.35" (9mm) to 0.55" (14mm) of continuously variable spacing *
- Allows you to securely set or vary the spacing between M48 thread components such as cameras, reducers, correctors, filter wheels, etc. or control the orientation of your camera
- Spacers can be stacked together in various combinations to achieve just about any spacing between 0.35" - 3.11" (9mm - 79mm) and fine-tune the spacing to within a fraction of a millimeter
- Each spacer has 48mm threads (male on one side and female on the other)
Features:
- Precision machined from aluminum and black anodized
- Variable spacer consists of 2 parts:
- The first part is a fixed spacer tube with a barrel length of 6.1mm and a really long male M48 thread. This part can possibly be used by itself as a 6.1mm spacer*. It has an outside diameter of 2" so it can be used in 2" focuser tubes or eyepiece holders.
- The second part is a 1.6mm thick M48 threaded lock ring that slides over the male thread of the first part above. By moving the location of the lock ring over the male thread, you can adjust the total spacing of the combination.
Specifications:
All Spacers
- Thread Specification (External Thread) = M48x0.75 Male
- Thread Specification (Internal Thread) = M48x0.75 Female
- Clear Aperture = 1.79" (45.4mm)
- Maximum Outside Diameter of Barrel = 2.00" (50.7mm)
- Combined Weight of All Included Items = 2.2oz (64g)
Fixed Length Spacers
- Total Spacer Lengths = 0.39", 0.59", 0.98" and 1.38" (10mm, 15mm, 25mm and 35mm)
- Extensions Provided = 0.20", 0.39", 0.79" and 1.18" (5mm, 10mm, 20mm and 30mm)
- Length of External Male Thread = 0.20" (5mm)
- Lengths of Internal Female Thread = 0.18" (4mm) in the 5mm spacer and 0.33" (8.5mm) or longer in the other spacers.
- IMPORTANT NOTE: Since the female thread length of the 5mm spacer is shorter than the male thread lengths of the other fixed-length spacers by 1mm, the total extension provided will be longer by 1mm if you affix the 5mm spacer to the male thread of the others (i.e., the effective spacer length becomes 6mm). You can maintain its 5mm length by attaching the male end of the 5mm spacer into the female end of the others instead.
Adjustable Length Spacer
- Total Length = 0.63" (16.1mm)
- Extension Provided = Variable from 0.35" (9mm) to 0.55" (14mm) *
- Length of External Male Thread = 0.39" (10mm) total consisting of 2mm unthreaded undercut and 8mm threaded section
- Length of Internal Female Thread = 0.20" (5.1mm)
- Maximum Outside Diameter of Lock Ring = 2.21" (56.2mm)
- Length of Lock Ring = 0.06" (1.6mm)
Additional Information:
* To get a specific spacing within the 9mm - 14mm range of the adjustable spacer, your accessory threaded on to the male thread of this spacer must have a proportionately long female M48 thread. For example, at the minimum usable spacer length of 9mm, approx. 7.1mm of the male M48 thread is exposed. If your accessory's female thread is shorter than this, it will not thread on fully and the effective spacing you get will be longer than 9mm.
Also, at the maximum variable spacer setting of 14mm, you will be left with approx. 2mm of the male M48 thread length for attachment which will be sufficient for most applications.
