My best guess is something in the EQ6 - GM11 category, i.e 50-75lb load capacity
作者对比,DIY的赤道仪有EQ6, GM11级别,50-75磅载重。

作者买的材料: [*]2x 30mm ID 62mm OD twin row angular contact bearings (SKF) about £20 each.[*]2x 30mm ID 62mm OD twin row self aligning bearings (SKF) about £15 each.[*]1m 30mm OD shaft steel from RS about £50[*]About a dozen 10mm Oilite bronze bushes, about a quid each.[*]Meade DS motor kit with Autostar control.er (about £50 from a friend)[*]4 timing pulleys and 2 timing belts for drive transmission ・about £30[*]A large number of M16, M12, M10 , M8 and M5 nuts, bolts, washers, fixings, studding etc. There are several hundred such items, so it adds up. (no idea £30 ???)[*]Lots of tins of paint (£25)[*]Red anodising dye (£10)[*]Various lubricants (£10)[*]8 shaft collars ・about £25[*]Metal stock, aluminium bar and plate, silver steel round bar etc (no idea, c. £150)[*]Lots of sanding, polishing and lapping materials (£20)[*]Many bits items have been begged, borrowed, donated, pinched or scavenged. E.g. the 120mm OD bearing upon which the whole thing sits.[*]Two sandwich cake tins. £5 (since you ask, also known as prefabricated worm wheel covers).


这是在英国的买的成本£350-£500,作者不在乎省钱,而满足于DIY过程,
对于结果是更好还是更糟,作者开工前没有考虑。
但结果还是出乎意料的,30分钟不拉线,,周期误差20角秒,以前作者未尝试过。

Camera: Artemis 285 (Sony ICX285). 8寸F5牛反+彗差改正镜,
拍摄Pelican region星云,30分钟Ha
Optics: 8 inch F5 Newtonian with Coma Corrector..
Not calibration and only a quick stretch to process. Astrodon 6nm Ha Filter
