FI092 Screw-on Solar Filter 70 Ref: BCF-FI092
These solar filters have been designed to allow direct viewing or photography of broadband solar phenomena (sunspots, faculae etc). The filter is manufactured from glass and has a multi-layered metalised coating applied by a process of evaporation in a vacuum chamber. For safe and secure observation the glass filter is sealed in a high precision black anodised aluminium cell that screws directly onto the thread on the front of the telescope tube. For safety the glass filter is held in the cell with precision machined screws and not glue (or tape!) as in some competitor products. Solar observation can be dangerous but can be carried out quite safely by following simple precautions – please read and follow the instructions carefully.

Focus Master Information
Great astro-photography depends heavily on perfect focus. The Focus-Master is essentially a lens cap with three holes that simply fits over the end of the telescope and helps you achieve perfect focus in seconds. At first glance the Focus-Master is just a focussing aid based on the tried and tested principle of the three-hole mask. Now we have refined this idea and created a mask that not only offers the standard three-hole focusing feature, but by removing the special threaded cap you have a perfect off-axis aperture which has been matched to the useful viewing area between the secondary and the maximum diameter of the corrector lens of popular sizes of SCT. The result is a powerful and versatile accessory that has uses in focusing (photo and visual), lunar and planetary viewing, double star observation and collimation adjustment.
The Focus-Master has the additional benefit that it can be used as an off-axis filter holder for white light and H-alpha Solar filters by BC&F Astro Engineering & Coronado.
Focusing with the Focus-Master: Simply remove the three black plastic plugs (they just pop out by pressing from the rear) and attach the mask to the front of the telescope. If you observe a star of moderate brightness you will see that at an out of focus position you will be presented with an image not of one star but three. Adjust the focuser in the direction that causes the stars to move together and keep adjusting until the three stars merge into just one perfect image – and the scope is now focused. It really is that simple.
This process will work just as well with lunar and planetary targets and will allow you to focus the instrument perfectly even when the seeing is poor or on a dim camera focusing screen or CCD monitor. In these situations it can be difficult to tell the difference between one focus position and another. With the Focus-Master attached there is no uncertainty: if the image is out of focus you will see not one but three images. Adjust the focus and make the three images merge into one and the instrument is focused. Simply remove the mask and you are ready to begin imaging.
But the story doesn’t end here. One aperture of the Focus-Master has a special threaded rim that enables our range of precision-mounted glass solar filters to be screwed into place for off-axis viewing (see solar filters for more info). If this isn’t enough, the Focus-Master also provides a good method of checking and adjusting collimation. Still not convinced? The Focus-Master has three large plastic plugs for it’s holes so it makes a perfect replacement dust cover as well!

PH024 Tiltable Piggy-Back Bracket Ref: BCF-PH024
Tiltable camera mounting to fit the LX 10” SCT telescopes with tube mounting rings. Take perfectly tracked astro-photos with your Meade, Helios, Sky-Watcher, Celestron and many other tube ring mounted telescopes. Camera head tilts to allow camera to point in different attitude to telescope. This very rigid mounting is a major improvement over ball-and-socket type attachments. Locking grub screws prevent sudden camera rotations and slips. A comprehensive bolt-kit is supplied to allow fitting to most ring mount telescopes. If you have a threaded hole or a threaded stud (often with metal or plastic hand-wheel fitted) on the top of the telescope tube mounting rings then this camera mounting will fit your instrument.

PH047 Ultra Standard afocal camera support Ref: BCF-PH047a
The easiest way to get into astro-photography! The Ultra Standard is a simple and lightweight way to mount any camera onto to any telescope with a 1.25” eyepiece holder, and take pictures through the instrument’s eyepiece. The Ultra does not use your camera’s filter ring (as this risks damaging your camera and invalidating the warranty), instead the tripod socket carries the camera’s weight, just as the camera manufacturer intended. Clever design allows the Ultra to fit virtually every camera available. Fits directly onto any 1.25” fitting eyepiece.
