Hi all,

Here's a few images I took this month from my super dark sky backyard:

What mount is that? It looks like an EQ5, but with little black boxes for the motors.

Thanks, been out of the loop for a while. Is that a new-ish mount?

New-ish, been around 2-3 years at a guess. If you zoom in to the photo, you can see the letters EQM-35 PRO on the control box.

I have one, I really like it. It's essentially an EQ3-2 (scope payload capacity 4-5kg ish) with the 10kg scope payload capacity of an EQ5. The "M" stands for modular, as you can take it apart to act as a tracker-only for mounting a ball head and DSLR for example.

Cheers, Magnus

Its worth noting that its also got a bigger RA gear that the EQ3 or EQ5 and so guides more accurately.

Having owned both the EQ5 and now the EQM-35, that bigger RA gear does makes a positive difference.

M42, luminance only at 60 and 2 seconds. Final image binned 2x2.

Collimation needs a tweak as stars are slightly off, pixel peepers!

This image was both a failure and a success at the same time. It was my first time shooting the rosette, and I wanted to make it a good one.

I was able to get 20x2mins on Saturday, and 40x2mins on Sunday. Although all of the images on Sunday became completely unusable, I accidentally had the DSLR slightly rotated within the focuser, and I guess more people had their lights on because LP was significantly worse.

So I was only able to use a small portion of the frames I collected, about 40 minutes. 

Although I felt like I really resurrected the image from the grave in post processing. I learned a new technique for gradient removal (the image had the worst gradient possible). And while it’s definitely not great, it looks a lot better than I expected it too be considering the state of the picture.

Just got my 130PDS and first clear skies so captured the Orion nebula as first target of choice.  Very pleased with the decision to purchase this scope.  Processing could use a little work, looks like some blueing at the edges (maybe bad flats?)

This is my first full colour picture from a mono camera 🙂

This nebula sits next to Navi in Cassiopeia (Gamma Cass)- apparently the star is gradually eroding the nebula. The nebula itself is both an emission and a reflection nebula, but I think I’ve only managed to capture the emission parts here.

I took this over 2 nights on 15th and 17th Jan. It’s been a bit of a learning process to put this together:

40 mins of 2 minute subs in each of LRGB on 15th

100 mins of 5 minute subs in Ha on 17th

It certainly takes a bit more effort to process mono, and it wasn’t helped by loads of problems with ice and fogging on my secondary. This led to not getting much Ha signal, and I’ve used layers in Gimp to bring it out (don’t tell Pixinsight- they’ll excommunicate me!). I think there’s probably more can be extracted from this data- especially around the body of the nebula- but I’m still pleased to have a full colour image!

I had another go at this a few days later and the whole scope completely iced up- see picture at the bottom!1518295051_GhostHaRGB200115.thumb.jpg.243f3011ffca1e2120d33f8353bab01d.jpgIMG_20200119_095755719.thumb.jpg.f357e98cdd518ef001c833655abbfa32.jpg

Awesome Image, is the 290 your only camera or just using it for small targets? 

Thanks Adam :)

I currently have the ASI290MM-Cool and ASI290MC-Cool. One for narrowband and luminance and the other for RGB. I have owned a number of cameras over the years, but I sold them off to finance other projects. 290 is a great little sensor, albeit small.

Cheers

Thought I would link this in here as this is the thread that got me started with the scope.

Just curious, what guiding setup would be ideal to start with the 130pds on heq5 to good more length on the subs ?

Hi

2 alternatives shown here. An off axis guider with t7m or 60mm guide telescope, discontinued zwo120mm and 40mm dovetail clamp. Black shower cap optional.

Hi everyone.

Not had the little 130 out for some time, so to redress the balance here's a -bit disappointing- cone nebula. Disappointing through impatience more than anything; need more frames, but there's so much going on below e.g. canis major stuff I never get around to...

There's something there but not enough.

Thanks for looking and all comments most welcome

Cheers and clear skies.

I went from a QHY miniguidescope on the findershoe to an evoguide 50 screwed onto the top dovetail of the mounting rings and saw a huge difference in guiding i.e. went from a total RMS (px) error >1.5" to ~ -0.5-0.7".

Hope this helps.

Minos

 

P.S. excuse the cable wrapping mess...also, you can see that I'm now using the qhy finder rings to run camera cables through..!

      For sale - A well looked after immaculate condition Sky-Watcher Startravel 120 ota including tube rings/dovetail, 2" Sky-Watcher dielectric diagonal and 2" Baader Semi-Apo filter - £290. 
      There are the usual pock marks on the dovetail bar and a couple of scratches on the diagonal nosepiece caused by retention screws. The ota objective is dust free. Only selling due to a purchase of a 150mm  newtonian, (the viewing position doesn't kick off my bad back) and I don't have storage space for three telescopes.
      Brand new these items would cost in the region of £440.
      I will consider splitting the items only if the package doesn't sell within a reasonable time.
      Collection only from Liverpool. Payment via Paypal (buyer pays fees) or cash on collection.
      Social distancing rules required.
      PM if interested. Thanks for looking.



      + 2" to 1.25" draw tube adapter and end cap. There's also a 2" end cap no shown in the pics above.

      Hi! I'm very new to astronomy and have ordered a SkyWatcher StarQuest 130p as my first telescope, which arrives soon. As I understand it the tripod is the biggest weak link in the setup. Is it possible for me to buy a replacement, better tripod to improve my viewing experience overall?
       
      Apart from the tripod what would you recommend upgrading?
       
      Thanks!

      Hello!
      I am trying to setup the Skywatcher MC 102/1300 SkyMax BD AZ-S GoTo telescope+mount.
      What I did:
      Start from parking mode. The telescope is aligned to north. Turned it on and aligned with 2 stars. During the alignment the tracking is turning on all the time and moving the telescope position. Then when I try to go to some star the north/south motion never ends. While the East/West motion stops at right location. This is really wild to me. Can someone help with understanding what is the problem ?
       
      Thanks,
      Gevorg.

      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!

      Was looking for a simple and sturdy 3-legged stand or table to raise the height slightly of the Heritage 130p when viewing on the lawn away from my garden table and so my 7yr old daughter can stand and observe easily. 
      Suddenly came across this thread on Reddit which seemed to have the perfect solution from our Swedish friends at Ikea... https://www.reddit.com/r/telescopes/comments/doi3n5/skywatcher_heritage_130_or_awb_onesky_ikea_kyrre/ (see pictures below) and also discovered some more customisation ideas for the same stool in this thread from across the pond...https://www.cloudynights.com/topic/463109-onesky-newtonian-astronomers-without-borders/?p=9734431
      The UK Ikea store sells the stool in plain solid birch (£10) or stained black/blue (£12) and delivery is just £3.95...have a black one on order (wont arrive until 5 June though) and will report back when I, have it... https://www.ikea.com/gb/en/p/kyrre-stool-black-70434976/
      Anyone else used one or made something similar for this fab little scope?
