Setting up my new HEQ5. The same issues are present (by design) on RA setting circles on the other mounts?
Instructions missing for RA setting circle thumbscrew
Can the RA setting circle actually be used as a normal setting circle - it seems just "cosmetic". It's either locked or slips when free to rotate.
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)
I am trying to plan out my longer term equipment strategy, rather than go for impulse purchases and would like some advice on dual mounting scopes.
At present I have a roll-off shed with steel pier in concrete block. The mount is an HEQ5-Pro, stellar tuned and belt driven which is supposed to have an astrophotography payload of around 11Kg. My main camera is an ASI294MC. Guide camera Lodestar x2.
I switch between two scope set ups. (Weight for both includes cameras and filter draw.)
• ES102 with 50mm guide scope, FL=714, weight is 7.5 Kg
• C8 (not edge) with 6.3 FR and OAG, FL = 1260, Weight is 8kg
So clearly I cannot mount both on my HEQ5 Pro.
One of the reasons for going with a fixed pier in a shed is that once set up and aligned, I can just push back the roof, align, focus and get imaging in 5 mins. However as targets change I need to swap scopes, rebalance, rewire etc. Not a massive effort but I am wondering if I could dual these scopes and perhaps eventually add something like a WO GT71 FL= 420, weight 2.93 for the wide stuff. So total weight around 19kg. Then maybe in the future go for a Mono camera and filter wheel and even perhaps an C9.25 Edge pushing the weight to around 23kg.
To do this I would plan to buy a CEM 60 mount that claims a payload of 27.2 kg, although it is not clear if this is imaging, although I can’t see why anyone would buy one just for visual. I would then just guide with the OAG.
So I have two questions:
Is this a realistic strategy or would I loose guiding accuracy by loading the mount in this way. Perhaps even compared to keeping the HEQ5-Pro and swapping when necessary. Or maybe just forget the GT71 and C9.25
If I do go down this route, what is the best way of dual or triple mounting? I have read that mounting two dissimilar scopes side by side risks unbalancing the setup, but also that mounting the ES102 on ADM rings risks flexure.
Any other advice or observations most welcome.
I was hesitant to write this earlier, but I wanted to try all possible ways to get my new SkyWatcher 250P GOTO allgined, but to no avail.
I have followed the instruction manuals of both the synscan and SW, and managed to get the message "alignment successful" multiple times on the handset or the app. The closest I got when I tried to dial a different star was a 20 to 25 degrees off on the azimth axis. Most times it's off by a margin on both axes.
I have tried aligning around 30 times on more than 5 diffrenet occasions, different locations as well. I end up ignoring the thing and switch to navigating manually as the eager friends want to observe instantly, but we ran out of objectes and the planets are not close anymore, so I figured it's time to get deeper DSO's and sort out the GOTO.
Here is what I do:
• I level the scope to the zero reading on top of the base
• I make sure the base is level with a spirit level I bought recently
• I point the scope northish, but latley I bought compass to pinpoint north
• I plug all equipments in and then switch on the power from a lead acid battery
• I enter the date ( US fromat, month before day 😕 )
• enter correct time zone obviously
• the coordinates in the format of E 000 00 , N 00 00
• As for elevation I use "my elevation" app, not sure if it's accurate. Does this entry have to be that accurate?
• I tried both brightest star and the 2 star align methods on the handset (which seems to be the same thing apart from the brightest method having an extra menu asking for which direction you are pointing at)
I even used the synscan app and the synscan pro, and tried the 3 star align method. The app uses location and enters all data automatically
•I use the top and right arrows as the last press before centring the star in the eyepiece as recommended by the manual
These are the steps I follow when I align , is there anythung I missed? Your kind help is much appreciated.
Update: issue solved, check the reply in the second page
I tested the tracer polymer battery over a six hour period and although the red light on the HEQ5 flashed most of the time, and more rapidly as time went on, the mount moved so that the time on setting circles changed by six hours, suggesting the mount will track OK. (the test was carried out during the day). I did not try to get the telescope to point in a different direction using the handset.
1) Should I be bothered by the flashing lights on the HEQ5 mount?
2) Is tracer misleading people by saying their batteries are 12 volts? (they say that their discharge curves are flat)
I found that the battery's voltage falls. Below is from the Tracer datasheet.
