    Keele Observatory

    My son is a student at Keele. Visited the observatory on several occasions, enthusiastic staff, impressive telescopes, especially the refractor. Unfortunately, I've only managed one clear Tuesday night that coincided with my visits. I had a superb view of Jupiter at 200x through the Grubb, earlier this year. Plenty of fine detail visible in the belts. Well worth a visit, solar viewing on Saturday afternoons. Best of luck with the weather though!

    UK astronomical component suppliers

    You could try : Emerson Optical Co. Ltd., Unit 4, Oxgate Centre, Brent, London NW2 7JA. Tel 0208 208 1599. They have made 4 inch and 6 inch achromatic objectives. Alan Montague was the person to contact. Jonathan Owen based in Longsight, Manchester ( may have moved ) made objectives, achromatic and apochromatic. Don't know if he is still in business. HTH

    Making a dew shield, what do I need?

    You can use cardboard to make a dew shield. Cut to size, you can use cardboard from a strong box, corrugated type is best. Glue along the overlap and to maintain rigidity and shape glue strips of cardboard to the outside edges of the tube ends, Flock the inside and paint the outside of the tube with oil based paint to waterproof, especially at the material edges . Ensure shield is of adequate length, 2xtube dia minimum. I've got cardboard dew shields that have lasted for decades.HTH

    Mars: Syrtis Major on show

    I observed Mars on Friday and Sunday nights. Syrtis Major was on the meridian and despite Mars getting noticeably smaller was easily seen. The northern pole cap is now small and dim. Hellas above Syrtis Major (southern limb) was very bright on both nights. Gives the appearance of being able to see both pole caps.

    My 4" refractor is an Irving?

    I may be able to add some information about your telescope. I have a 3 inch refractor which is identical to the one shown in your pictures, even has an Irving focusser. I bought it new in late 1979 from a Mr Wood who lived in Welwyn Garden City and traded from his home. He used to advertise 3 inch and 4 inch refractors in the Exchange and Mart. I believe he was still advertising in the late 1980s to early 1990s. I think he or an associate assembled the telescopes from parts. My telescope has an uncoated cemented doublet which he told me was made by Bausch and Lomb in Mill Hill. I also have a 4inch Irving refractor which looks very different and is in a different class.
