Note: This scope is in the USA, so international shipping may prohibit a sale. However, without the heavy Scopeguard case the shipping cost will be substantially reduced.
I can provide a full frame image taken with this scope if anyone is interested.
Reduced to £3155 for the complete package. I will consider offers, but this is already close to my bottom price.
I’ve decided to sell my Takahashi Epsilon Ɛ-180. The scope and optics are in good cosmetic and optical shape. There are a few minor tool marks around the collimation screws but otherwise no issues. The primary mirror is centered with a Catseye Hotspot.
The scope will come with the Takahashi corrector, rings and top plate ($457 add-on), front cover, Scopeguard case ($500 add-on), BT Technologies dovetail bar ($150 add-on) (has a blemish but is super solid), Astrozap dew shield and cap with focus mask ($175 ad-on), Precise Parts Tak corrector to M48 adapter ($110 add-on), the Takahashi collimation tools, an M68x1 male to M54x0.75 female and a M54x0.75 male to 2" compression ring adapter ($100? add-on) (these allow you to use the scope visually with 2" eyepieces.)
I replaced the stock focuser (included) with an Optec TCF-Leo focuser with temp probe. With the included scope adapter and Tak corrector adapter this is a $1400 add-on.
Total new cost = £5900
All of this for £3155 plus shipping.
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.
