Flocking a SkyWatcher Heritage 130p flextube dobsonian

Recommended Posts

Posted (edited)

Found various threads on here and other forums about flocking dobsonians/newtonians but couldn't find specific images of disassembly of the very popular SkyWatcher Heritage 130p flextube and flocking of the OTA.

So having ordered some DC-Fix black velour sticky back material (can be got from various places including FLO) I thought i'd share some photos of the process from start to finish as it may help someone else in the future... 

Images below with notes... 

1. Focuser and shield flocking

This was the easy bit. A strip stuck inside the focuser, and just unscrew the shield, draw round it, cut the material and align and smooth down. In the last image above you can already see the significant improvement on reducing reflections comparing the flocked shield to the unflocked tube...

Notice my version of Bob's Knobs on the secondary mirror which are just black steel M4 25mm knurled thumbscrews bought off ebay for about £7 - along with the thumbscrews already on the 130P primary mirror this makes any fine collimation easy and completely tool free! 

For full stealth mode I've also painted the edge and rear of the secondary mirror, and any exposed screw heads with blackboard paint to reduce reflections. 

 

2. OTA disassembly and tube before

Note the cutout in the lower primary housing and the top ring. This aligns with the ridge of the tube seam, and means there is only one way to reassemble the telescope tube and mirror and one place for the handful of screws (4 at the bottom, 3 at the top). You'll also need an allen key to remove the 3 bolts for the dovetail mount. Simple! 

Now you're ready to Flock 'N' Roll! 👍🏻

3. Flocking the tube

You'll need approx. 50cmx29cm of the material to do the tube in one go, starting along the seam. As others have described just take your time here, peel off about an inch of the backing and get the edge aligned with the tube seam stick down firmly and smooth out any air bubbles. 

Then slowly keep peeling more backing (rip and remove if the excess gets in the way) and smooth down as you go, turning the tube and affixing the velour material. 

 

4. Finished flocking and close up during application so you can see contrast/reflection comparison of before and after.

All in all only took around an hour so not a hard job as long as you prepare and concentrate! I ordered one sheet of 45cm x 1m material which was plenty, however if your not as confident you'll get it right first time then order 2m so you have more to spare if you need to start again. 

Looks great, so as always I now just need clear skies to go play and see the difference it makes!

Thx for sharing, good work.

Do not you think about putting the shorud?

That looks super smart and effective.

Have you tried it out yet? I bet it's like a different scope now!

Thanks for sharing and motivating us heritage owners to do the same!

Nice job Callum, that should be a good improvement. These are excellent little scopes, and well worth putting some effort into.

You might want to consider a shroud for it too; I found that my breath was causing tube currents, particularly on high power targets like doubles and a shroud cuts that out completely, plus any stray light too. Some thin hobby foam and glue is all you need.

My first one wasn’t very good, it was wrapped around the outside but having seen what others had done, my Mark II version fits inside and slides down with the whole assembly into the bottom OTA, much neater.

Enjoy the scope!

      Finally got to image Mars this year after some appauling weather in the UK. 
      This was my first time out using the ZWO ASI 224MC on a very cold eve.  I think i've probably the maxed out my equipment (Skywatcher 200p) and the location (back garden in the middle of an estate) for this image, so pretty pleased with the results.  Its 15% of 11000 frames stacked using Autostakkert, and Registax used to bring out some detail.
      Equipment used:
      Skywatcher 200p with dual speed focuser, EQ5 mount with dual axis motors Tal x3 Barlow ZWO ASI224mc with IR Filter  Lenovo x270 laptop running SharpCap  Image Processed in Autostakkert, Registax and photoshop

      Good evening all, I am looking for help/ advice on a telescope I have had for a few years and don't know how to set up , it is a SkyWatcher and had a motor and something which looks like one can set up co-ordinates with, can anyone shed any light on this ? 
      Thank in advance,
      Chris.

      Looking forward to receiving my 102MC in the next few days/weeks depending on supply. Does anyone have any experience, tips/advice?  Looks like a good grab and go particularity for planetary observation - interesting “next generation” mount.

      Hi everyone,
      I'm completely new to telescopes and know nothing but I want to learn and I need some advice!
      I have a budget of £200 which I can't stretch. I really like both the Skywatcher Heritage 150p and SW Skyliner 150p which I believe has been along longer than the Heritage.
      I would like to take the scope out occasionally to dark skies (so the heritage would be easier to transport) but with 2 very young children at home the reality is that I will mostly be using the scope in the back garden.
      Obviously both scopes are 150p but come with different accessory spec (specs below).... please could someone advise which would give me the most bang for my buck?!
       
      Heritage 150p:
      Magnifications (with eyepieces supplied): x30 & x75
      Highest Practical Power (Potential): x300
      Diameter of Primary Mirror: 150mm
      Telescope Focal Length: 750mm (f/5)
      Eyepieces Supplied (1.25"): 10mm & 25mm
      Parabolic Primary Mirror
      3-arm Secondary Mirror Spider Support
      Red Dot Finder
      Wooden Alt-Azimuth Mount
      Collapsible/ Extendable Tube Assembly
      Weight Approx 7.5kg
      Supplied with Gift Box
      33% more Light Gathering than 130mm
      Skyliner 150p:
      Magnifications (with eyepieces supplied): x48 & x120 Highest Practical Power (Potential): x306 Diameter of Primary Mirror: 153mm Telescope Focal Length: 1200mm (f/8) Eyepieces Supplied (1.25"): 10mm & 25mm Parabolic Primary Mirror 0.5mm Ultra-Thin Secondary Mirror Supports 6x30 Finderscope Direct SLR Camera Connection Wooden Alt-Azimuth Mount with Accessory Tray 73% more Light Gathering than 114mm Many thanks!

      For sale is my beloved but now superfluous to requirements HEQ5 Pro for £650
      It's in a used condition as you would imagine. I've had it for about 4 years and found great success with this mount. Ideal for those beginning astrophotography and also good for visual users.
      I'm calling it "deluxe" due to the upgrades I've had done.
      - It's belt modified
      - It's had brand new bearings and grease
      - The backlash has been expertly setup 
      - It has the latest polar scope
      - The power port has been replaced with an aviation style port which is a lot more secure
      It'll come with the hand controller and at least 1 counterweight (if I can find the second it'll come with both). The polar scope cover has been lost. The counterweight is rusty as always. There is some marring on the counterweight bar housing as shown in the photos.
      It also will come with the modified power cable required also.
      Note: the power LED sometimes doesn't illuminate but the mount is still powered (please see the photo with the hand controller).
      Collection or local delivery within Northampton
