dawson Posted August 24, 2013 Share Posted August 24, 2013 (edited) Inspired by Felix [as always] (http://www.eastmidlandsstargazers.org.uk/topic/4108-right-angle-polar-scope-viewer/) and getting really hacked off the other night with wet knees, stiff neck and aching back, I've gone down the right angle polar viewer. First I got a right angle view finder off ebay (mine was £20 but you could find a suitable one cheaper if you looked hard I'm sure): Next I got a 32mm end plug (plumbing part) from B&Q (available at other hardware stores too): http://www.diy.com/nav/fix/plumbing/plumbing-supplies/waste___overflows/-specificproducttype-overflow_tubing/FloPlast-32mm-PP-Push-Fit-Waste-Access-Plug-Black-11478395?skuId=11989102 Astro Leigh got his tool out and some safety specs (his wife was watching from inside the house): Then I got Astro Leigh to drill my hole: As he'd drilled to just the right amount, the right angle viewer fitted in the hole just right (after we'd removed the square metal plate): And now the awfully positioned polar scope viewing hole: Has been put into a more comfortable position as the whole thing just pushed on to the polar viewer: Now all I need to work out is how to polar align now the image is flipped in various planes... Thanks Astro Leigh, and thanks Miranda for the tea Edited August 24, 2013 by dawson Link to comment Share on other sites More sharing options...
dawson Posted August 24, 2013 Author Share Posted August 24, 2013 (edited) Not sure how to make the images ust appear directly from photobucket; I tried the obvious options. James P.S. Just worked it out (get link codes) Edited August 24, 2013 by dawson Link to comment Share on other sites More sharing options...
+RonC Posted August 24, 2013 Share Posted August 24, 2013 Very good James, question; how did you remove the square bit off the end of the angled viewer?? Link to comment Share on other sites More sharing options...
dawson Posted August 24, 2013 Author Share Posted August 24, 2013 The one i got off ebay (carefully selected) had four very small screws which held the square plate onto a screw on ring. In fact, while i did remove the plate using the screws, in the final version of the device, the screw on ring wasn't used either, so i could have just unscrewed it all. That is why i used the words "suitable one" above, as i think working out how to attach the right angle viewer to the 32mm plug is key. Also on mine, i can screw the focus on the polar scope right inwards, and then use the focus on the right angle device itself, to alter focus (well i can in day light anyway).

+RonC Posted August 24, 2013 Share Posted August 24, 2013 I only asked because I have an Olympus one with a zoom on the square piece. I'll check it out! I do have a polar cam if I need one as well! Cheers Ron Link to comment Share on other sites More sharing options...

dawson Posted August 24, 2013 Author Share Posted August 24, 2013 I can't really take any credit for anything. Felix had the idea, I ordered the bits, Leigh did the handy work. Hopefully I'll reap the benefits (well my back anyway). JD Link to comment Share on other sites More sharing options...

Rock Doctor Posted August 27, 2013 Share Posted August 27, 2013 Felix, when I get chance I'll post some piccies of a polarscope illuminator that you might find useful to go with it. Link to comment Share on other sites More sharing options...
catman161 Posted August 27, 2013 Share Posted August 27, 2013 Ooh sounds cool Dave-would be interested to see that thanks Link to comment Share on other sites More sharing options...
Rock Doctor Posted August 29, 2013 Share Posted August 29, 2013 Felix, I tried but couldn't figure out how to attach a photo to this thread. In essence it's a white plastic tee (I think 18mm) used in plumbing that will fit in the hole of the mount. a plastic bottle cap is then used to hold a 12v red led in the arm of the tee that is at 90 degrees to the two arms that are straight through and a length of cable and a jack plug is attached to the led so that it can be powered from a dew heater controller or12v psu. One end of the straight through is then inserted in a cap or bung of some description to hold it in the exit hole of the polar scope. I use mine in one of the dew heater sockets so that I can use the pot as a dimmer. I have used an attachment for a fountain to make the bung with some rubber tape but I'm looking to improve this to give a better fitting in the mount Link to comment Share on other sites More sharing options...
catman161 Posted August 29, 2013 Share Posted August 29, 2013 You have to have a Flickr or photo bucket or other image hosting account and then you link the pics here in the forum. Thanks anyway Dave, the description is good Link to comment Share on other sites More sharing options...
Rock Doctor Posted August 29, 2013 Share Posted August 29, 2013 I'm trying to get across to EMS2 for one of the nights, either Fri or Sat. I'll bring it with me so if you're there you can have a look. Failing that I'll bring it with me when I next go over to Kims for a cuppa Link to comment Share on other sites More sharing options...
+RonC Posted August 29, 2013 Share Posted August 29, 2013 I've just re-adjusted my SW polar illuminator and used it to light the setting circle on the Dob!! Link to comment Share on other sites More sharing options...
Rock Doctor Posted August 29, 2013 Share Posted August 29, 2013 Felix, I based it on this http://www.cloudynights.com/ubbthreads/showflat.php/Cat/0/Number/4137245/page/2/view/collapsed/sb/5/o/all/fpart/1 Link to comment Share on other sites More sharing options...
catman161 Posted August 29, 2013 Share Posted August 29, 2013 Hey Dave, I see I think I got the wrong end of the stick. I though it was to attach to the right angle polar scope viewer. My polar scope reticule is already illuminated so I have no need for a secondary illumination device. Cool bit if DIY though Link to comment Share on other sites More sharing options...
