Now the dark season has started for us who live in Sweden. Then we must have all our equipment in top condition. I have one mini mount, the Star Adventurer, I'm very satisfaid with it. But you can always get it a little bit better. One small problem I have is that the altitude lock of the wedge slips. Maybe others of you also have this problem? Here I have some photos and my attempt to get it better: http://www.astrofriend.eu/astronomy/projects/project-star-adventurer-modify-wedge/project-star-adventurer-modify-wedge.html I will test if my modifications work in reality next clear sky. /Lars
Took the bull by the horns and done the power modification on my Eq6 pro to connect via the 2pin connector , bit nerve racking haven’t really done much soldering before ,managed to do soldering without frying anything, used Blu-tac to isolate surrounding area so I didn’t solder anything I shouldn’t have , mount powered up checked slewing with handset , steady red light voltage reading 14v dropping to 13.9v slewing phew ?
Folks just a short note to share a modification which some of you may find useful. The standard Crayford has fairly poor focus accuracy as we all know. But rather than chuck it and buy the twin speed version at about 150 quid... try this first. Simply double the gearing ratio by reducing the dimaeter of the spindle. I used a 2.5mm screwdriver and a ball of tape to give me a handle. The original spindle is abour 5mm So in stead of 3 full turns to rack end-to-end, you get amnost 6 full turns of the spindle. here is a fairly crude yet very effective implementation using a precision scredriver. this has greatly improved my focus accuracy! ...and as a bonus it can how hold my DSLR without applying the focus lock! Hope you like it and give it a go! Cheers Ray
Hi guys, I've been looking at Genius Facecam 2000 webcam for astrophotography use and it seems intriguing. It has a 2-megapixel CMOS sensor and a manual focusing, which seems quite good for modding, but it's hard to tell if it's wort trying, I have found no reference to astrohptography modding of it anywhere on the internet. I was wondering if any of you have experience with this webcam for astrophotography use? If so, share your thoughts.
Phew! Finally finished off my az3 mod to add some weight/s to the front end of the scope. Just finished attaching it to the scope, and tested it out with my heaviest load with the 2" diagonal & the Meade 40mm EP which weighs a ton on it own (combined weight just over 1.7kg). Works even at the highest point the scope can go and winds down OK with two weights fitted. When the scope is horizontal the weights are clear of the legs still, so no issues to move it around left or right. For most EPs etc I think just one weight will suffice, but it is easy peasy to add the second one if needed. Now, bring on the clear skies!
I have a second (used) PST on its way to me, so before I get to the typical mods like replacing the objective, I was wondering if there was anything useful I can try with two PSTs first? The thought occurs, could I extract the etalon from the 2nd one and add it to the 1st? Double stack on the cheap. I'm not 100% sure on the threads but could it screw in series with the existing one? But would the positioning in the optical train be thrown out enough to make this unworkable? I'm not sure how much tolerance I have to work with here...
