The Astronomik CLS CCD Filter IR Blocked has all the benefits of the standard CLS CCD filter but with IR blocking built in.
This broadband light pollution filter works on all objects and can be used visually and for imaging with CCD and plain glass (full spectrum) modded DSLR cameras.
QHY CS Mount Adapter for QHY5-ll and QHY5-III series cameras.
This adapter is 5mm long and is designed to replace the 10mm C mount, which some cameras were originally supplied with, to allow use of CS lenses.
At present we only have mounts with clear glass (not IR block), as they have the greatest compatibility.
Our Low Profile M48 to T Thread Adapter connects T thread cameras / accessories to any scope, lens or accessory with male M48 (2″ filter) threads. If threads are fully engaged this adds 3.5 mm to the light path.
The Low profile T Thread to 1.25″ Eyepiece Holder with Additional T Thread is a versatile adapter that converts any male or female T thread to a 1.25″ eyepiece holder or visual back. Can also be used as a 15mm T spacer.
The IR Pro (742nm) Filter pushes the passband of the Baader and Altair IR pass filters further into the Infra Red. At these longer wavelengths, planetary images are much less disturbed by distortions in the atmosphere.
This is the best “Planet Killer” filter, based on research by Astronomik to determine the optimal passband for enhanced Planetary Imaging, with most amateur equipment.
Sensitivity of most CCD cameras is still fairly high in this region so smaller scopes (>5″) can benefit.
The SkyWatcher 9×50 Straight Through Finder is a high quality 50mm optical finder fitted with cross-hairs and supplied with bracket. Compatible with most SkyWatcher, Orion USA and many Celestron Telescopes. Makes an effective & lightweight guidescope when used with our Finder Guider Adapter and a suitable C mount camera.
HEQ5Rail Kit is a revolutionary solution to an age old problem with HEQ5 mounts – Bent Latitude bolts.
Please note, this kit generally fits without problem, however due to slight variations in mount manufacture over the years it may sometimes be necessary to “fettle” an installation.
