My leg weights are held on with a combination of velcro straps (to hold it roughly in place), then backed up with a load of elastic bands to make it a snug fit. That makes it easier to remove if you need to... tape would be a bit of a one-way process (and leaves residue on you nice new shiny OTA if left for too long).

Oh ok. I have some Velcro though it's of the heavy duty type - the stick-on is really hard to get off! Insulation tape is easy enough to remove. It's, um, just a metal tube! As long as it's functional, I don't much care! :tongue: I've left the scope in the box in my bedroom this afternoon - too cold for messing about in there. Will have a go with it tomorrow :)

Just a few of the goodies ive had from the 130pds over the past few months:            

All images have been made with a Canon450D (unmodded), on a HEQ5 PRO goto, 9x50 finder guider (QHY5). Me and my garden gnome: several M51 crops: M97 & 108: M81 & M82 (& NGC3077): M81

Not great pics from me, but this is what i got so far since beginning with AP in august this year. No guiding and maximum time of expousures 30 sek.

I just need to add, the velcro isnt actually stuck to the scope, I used it to extend the leg strap of the ankle weight so it fits the circumference of the OTA.... a bit like having a really big leg...lol.

Ah, I see! Still, I'm not bothered about sticking some Velcro to the tube itself. At the mo, it's still in the box! I'll definitely get it out tomorrow! :) As you suggested previously, it looks like there'll be little chance of actually trying it out this month :(

hi Rob 

do you have a focal reducer on your 130 pds and if so where did you get it, i find myself wanting to do a bit wider field shots than my 200 pds will allow.

Yes I do use a FR (of sorts), its just the Skywater coma corrector. As well as fixing the coma (but not as good as the Baader in that aspect), it has the odd side effect of being a 0.9x reducer. And that reduction factor is tuneable (ie: more distance = more reduction, but more coma). Ive managed to get mine running about 0.87x(ish), which translates to f4.4.

Though its great for NB, its not really apochromatic - so you need to refocus between filters (something you dont need to do with the Baader). If I were to do some RGB work, id probably switch to the other corrector.

After reading this post I'm considering selling my Celestron Astromaster 130eq and buying a Skywatcher 130 pds!  I can't quite afford the £450 200 pds at the moment. 

The images posted on here are absolutely amazing!!

I just want to say thanks to the contributors on this topic. I have finally.....finally....finally....got good balancing with the 130 PDS with my imaging train (100D + cc). I was going daft but then I read the posts.....and then made up 2 x 500g home-made counterweights, secured them to a spare large dog collar (literally), and velcroed them to the mirror end. It has worked like a dream. Thank you folks.

Now happy to recommence imaging with my EQ6 AZ GT. Cheers.

latest attempt from my little 130-pds

im quite out of my comfort zone with comets lol as this is my 1st time imaging one and 1st time creating a GIF...... still need to stack my comet data to give me a nice picture, i will get around to it once i finish processing my M31 data,,,,,, only been processing it for about 3 months lol

https://www.youtube.com/watch?v=JFpopWXFk08&feature?version=3&loop=1&playlist=JFpopWXFk08&feature

thanks for the info rob but i went the other way and got the 80ED with and FF so now i can get some Wider shots (when the cloud clears) 

Though its great for NB, its not really apochromatic - so you need to refocus between filters (something you dont need to do with the Baader). If I were to do some RGB work, id probably switch to the other corrector.

the only filter i needed to refocus with is the blue all others seem to be fine but then that was with the 200p ds and the skywatcher cc not sure if that makes a difference.

thanks again

No prob mate :)

Youre using the 383 with the 80ED reduced yes? Then i might suggest 900s subs as a benchmark, but certainly not below 600s as f6.38 does the 383 no favours.

yip it is the 0.85 reducer F/F for the 80ED.

hoping to go 1800 sec or more now that i can get over 1800 sec with the 200 pds without human error lol just want to try and get more without doing a mosaic all the time, it will help cut down on sub capture time if i can get it into 1 or 2 frames insted of 4 or 6 frames plus all the other problems with mosaics  :smiley:

thanks .

On balance it will work out quicker than the 200p for larger stuff, slower FR yes - but youre grabbing a lot more sky so youre cutting down on mosaics. Im currenty trying to finish a 6 pane mosaic - which seems to have taken forever! January wasnt a kind month for AP.

Thanks guys, hopefully if I can get another night or two (with no Moon) I can finish it off and present a full resolution version. Whether I get that night between now and the end of Feb is another matter! Something tells me I might still be doing this one at SGLX :)

      Skywatcher illuminated reticule eyepiece. It has a red crosshair pattern. I think it’s 24mm rather than the newer 12.5mm models. Great condition. Looking for £35 including postage from France. Thanks.

      Hi All,
      I am currently researching which setup to purchase as my first proper scope (once they are back in stock).
      I thought I had settled on the Skywatcher Explorer 130ps AZ GTi but then I saw the Skywatcher Star Discovery 150i for just a little more money.
      Could anyone please tell me the difference between the 2 OTA's (other than the different aperture size), and also the difference between the 2 mounts?
      I realise that the AZ GTi can be modified to run in EQ mode whereas the Star Discovery can't.
      Can the Star Discovery view all the way to the zenith or does the OTA catch the mount or tripod before it gets there?
       
      Thanks

      I've been trying to image a couple of galaxies per night, one pre and one post flip.  On early Saturday morning at 1:30am I changed over to M82, and acquired 63 x 3 mins subs, OSC, totalling 3 hours and 9 minutes of data. 
      Camera: ZWO 2600MC at -10 deg C, gain 100, offset 50
      Telescope: Skywatcher 250PX (blue tube), 1200mm F4.7
      Mount: Mesu e200
      Guiding: ZWO OAGv2, 290MM, PHD2
      Filters: None
      Software: APT for capture, APP and PS for processing
       
      I havent really had a chance to get much use out of this camera since I bought it in December, and I havent processed many OSC images before.  I've a bit of work to do, but still very happy with the quality of the data for just 3 hours of integration time.  I would like to add some Ha to this, but purposely didnt bother during the recent clear spell, as it was moonless nights and I gathered some broadband data on other targets instead.
       
      CC welcome.

      Selling the Sky-watcher r.a. motor drive for eq2/cg3 mount.
      I was using it on my Celestron Astromaster 130eq. I was able to do some astrophotography with it, 15-20  seconds exposure time.
      Price £27 plus postage
      Payment method: PayPal, family and friends method or commercial and  buyer will pay fee 3% extra
