I am associated with a college who had purchased a Celestron EDGE HD14 two years ago. Due to the high humidity of the place, there has been quite a bit of fungus which has grown on both the front corretor plate and the rear coma corrector lens which is inbuilt into the central hole. If anyone would know how to disassemble the EDGE HD 14 from the front and rear end it would be very beneficial. 

TIA

If you're going to attempt to remove the corrector plate fro the front of the SCT, remember to mark at which orientation the plate was in, this is very important, because it is calibrated to your telescopes optical system. If the corrector goes on in the wrong orientation that you will never reach full focus.

The back coma corrector, try to spray it with Isopropanyl 100% alcohol than distilled water, repeat and let it dry, see if that removes the fungus.... this is my touchless cleaning method and it works very well.... the distilled water dries streak free and being touch less, there is less chance of damaging the mirrors, lenses or coatings.

Given that it's an expensive scope and belongs to a college, I'd advise that they use a professional repairer.  Otherwise you could land yourself with liability for accidental damage.

      Hi. Just starting to use autofocus with the Celestron motor focus and SGP. Can anyone give me some starting points for step size, backlash etc. I’m getting there but wasting a lot of imaging time just trying to get this to work accurately. I’m currently trying a step size of 75 and a backlash of 50. Any tips most appreciated.

      I'm having a bit of a clearout to make way for a new project.  For sale here are a couple of items that have seen very litle use:
      1) Celestron Omni CG-4 GEM Mount + Tripod - £125 *** SOLD ***
      This is in generally very good condition.  There are a few marks, and scuffs consistent with normal use.  There are also a couple of minor (small) patches of surface rust on a few of the bolts and steel legs.  It has seen very litle use, and has been in storage for the past few years so it is time to find it a good home.  The small rubber tips that go on the very end of the feet have perished, so these won't be included.
      It includes tubular steel tripod, 2 counterweights, built in polar scope, built in bubble level and slow motion controls.
      Due to size and weight, collection would be preferred from the RG27 area.  If you are reasonably local, I would also consider delivering.
      Price: £125, but I am open to offers.  Payment can be made via Bank Transfer (preferred), Paypal or cash on collection
      2) ***SOLD*** Celestron Omni XLT 127mm Telescope ***SOLD ***
      Again this is in very good condition, and has been in storage for the past few years and has had very little overall use.  A few marks on the dovetail as is to be expected.
      It includes a small finderscope, diagonal and a 25mm eyepiece
      Can be collected from the RG27 area, I could deliver if you are reasonably local, or can be posted for an additional £8.
      Price: £110, but am open to offers.  Payment can be made via Bank Transfer (preferred), Paypal or cash on collection *** NOW SOLD ***
      Any questions please do let me know.

      Hi SGL
      I popped this topic on CN too but noone seems to know anything.

      I came by an old Celestron Ultima 8 pre-PEC. I really like the scope and the mount it may be that I have read too much of Uncle Rod's and other's praise that I feel this scope has some intangible personality and charm.
      Anyway...
      Circuitry in the base seems to work fine even though the batteries don't hold charge but drive the Ra axis . I have 2 replacement on its way to me.
      Now my issue: It didn't come with a hand controller. I know it is not needed for tracking, and I don't have a Dec motor but I find it would be useful for centering in RA and D.A.R.V. method drift alignment.
      I was on the verge of making a crude controller out of veroboard and 4 momentary switches that I thought to be correct from the info on various sites, but then I came across an Ultima 8 project that clearly showed the hand controller for my scope.
      The pic attached is the one.
       
      I am looking for help on how the dial and buttons are wired in and/or photos of the innards of the hand controller or if anyone knows what else is inside the handbox.
      The sources I was going on so far is a combination of the following 3 links:
      https://www.cloudyni...ding/?p=8015749
      https://onstep.group...in/message/6300
      https://github.com/garlick/ultima8/blob/master/base/README.md
       
      These of course don't include drive rate rotary switch in the middle and if I could I would really like to to restore the full ability of this mount without spending too much  on electronics. Plus I don't want to spend time and effort on wiring something that doesn't work.
       
      Oh and lastly I have no background  or experience in electronics just own a soldering station and a whole lot of determination.
       
      Thanks in advance
      Greg

      Hi all, looking for some help please! 🙏 I have a wedge for my 8SE and when using EQ North to align it, it says it is slewing to Vega but ends up all the way over at Polaris!?  Any ideas? 🤞🏻 Thanks in advance! 😊
       
      I have updated the firmware, Mount is pointing at north, have inputted my latitude and longitude, I have tried picking the nearest city too and nothing seems to work! 😟

      Has anyone used the celestron lithium powertank (the small one, not the pro version) with a skywatcher HEQ5?
      It looks like it should be perfect but that is coming from someone who is relatively clueless
      From the skywatcher specs, it looks like the mount needs 2 amps of current, and the powertank supplies 3, so that should be good?
      It also looks like the power cable is a double-ended tip-positive 2.1 mm plug, so i assume that even though it doesn't have one of those 12V car battery inputs, it shouldn't matter right?
      (just to save people some time, i'm not going to bother with a lead battery / leisure battery / jump-start pack / etc)
