Imaging with the 130pds

Recommended Posts

All being well :smiley: I hope to be contributing to this thread soon as I have just taken possession (thanks nightfisher) of SW 130P-DS

My intention is to use it on my pier mounted EQ5 so weight wise I think I should be ok compared to my 200p

"ok" will be a bit of an understatement! You will be able to lift it (fully loaded) with one hand.

Heh :) I see you wasted no time in getting it into your sig!

This is a nice thread demonstrating how great the 130pds is. Thanks for sharing your images.

Hi all

Damn, damn and blast it!! I really regret finding this thread!! The images you lot have been posting on this thread are amazing –I mean REALLY amazing! And to think they come from a sub £200 OTA is all the more incredible!! I doff my hat to you all. The time and dedication that you must put in to get these images is off the scale.

I salute you all, and keep them coming.

Now, to rethink my new set up – I was going to get a SW short tube frac, but looking at these images I may punt for a 130PDS instead! I am not heading into AP just yet, but I may as well spend the money on the 130 OTA to future proof myself!

Cheers

I'm not affiliated with them, but Astroboot has one for £110 at the moment - full 12 months warranty.....

It's almost worth buying for the dual-speed focuser alone at that price... ;)

Oh noes!! It has <Mysteriously> disappeared from the astroboot website...

Gonna set my Dremmel on my Revelation 10" in the near future. Sorry 130'ers, but photons rule the day! ;)

Ah temptation gone... in the immortal word of Shaggy, "It wasn't me..." - someone got a nice bargain though.

Looks like two of us on here picked up a 130pds from astroboot, they have had a couple on there, the one I grabbed was £99. Hopefully get my hands on it on Friday, just need to sort a mount now.

Blimey - that was quick. Had a gander at work and there it was. Checked back the following day and gone!!! I must be quicker off the mark next time!!

They seem to be averaging 1 a week at the moment, I missed out of a 150pds a couple of weeks ago.

This is M51 from Stockholm, Sweden sometimes feb/mar 2015.

183x60s subs using a Canon 500D unguided on EQ5 mount and of course the 130 PDS :smiley:

Used Drizzle 2x in DSS, then some processing in StarTools and then final adjustments in GIMP.

Thats a similar setup to mine except for the Pentax ist*DS...

So currently effectively limited to 30s subs.

Thats a superb image!

Thanks!

Here is another image of M81 using the same equipment.

Exposure is 202x60s.

These are lovely images with nice colours

They almost undermine the benefit of guiding  !

I always thought that the aim was to take as long an exposure as possible to reveal the finer detail ,  however you have revealed a lot of detail  with a large number of smaller exposures.

 I guess there is a limit as to when adding more exposures reveals anything further and the potential to reveal faint detail is greater with longer exposures.   However long exposures require good tracking and delicate setting of ISO levels so as not to over expose especially in light polluted areas.  This results in more bad subs during an imaging session.

The simplicity of shorter exposures cannot be underestimated in the light of these results !

Short exposures are ok if your telescope is fast, the target is bright, and youre not expecting to go deep. For the harder stuff, long subs are quite unavoidable (moreso in narrowband) because if you have something that barely shows up in one 1200s sub, its not going to appear at all in a 300s sub (ie: as 4 x nothing is still nothing!) :)

Looks like I will be joining the 130PDS club very soon - whoohoo.

Managed to find one on ABS for a good price.

Fingers crossed.

Welcome to the club!

I'm again considering getting a second one and attempting a dual shooter on my HEQ5...Clouds breed madness it seems :evil:

I also will be joining the 130PDS club. I ordered one this morning from Astroboot for £110. There was 2 on there this morning. Just waiting for it to turn up now.

I know Uranium235 has already posted one, but in the time I've had the CCD its about the only target I have managed and am happy with (with thanks because I never even knew the Propeller Nebula was there).

Nice image! It took me a couple of seasons to find that one as its slightly off the beaten track and doesnt appear in the handset (DWB catalogue). So you have to either use stellarium/CdC or bang its RA/DEC straight into the handset.

Other wierd stuff here:

there's this book too - http://www.amazon.co.uk/Observing-Handbook-Catalogue-Deep-Sky-Objects/dp/0521256658/ref=sr_1_2?ie=UTF8&qid=1432798460&sr=8-2&keywords=deep+sky+object+catalogue#reader_0521256658

gives an 'impossibly' detailed and comprehensive list of DSO's.  The sections on the big targets, where it breaks them down into individual NGC's by type is pretty interesting, for example if looking at one of your own andromeda pics you can identify individual star-forming regions, clusters etc

      Thought people may like to see my recent custom design for my SkyWatcher Heritage 130p... 
      As a big Apollo misson geek, and not being a fan of the stock astronomer names wrap on the 130p, I decided to get creative. 
      I used a great moon wall sticker just £6 from Ikea (https://www.ikea.com/gb/en/p/kinnared-decoration-stickers-moon-00448463/) as well as some matt vinyl stickers from Redbubble, one for each Apollo mission patch. 
      Below is pics of the mod in progress and the end result - would love to hear what you think!

      Hi,
      I have been attempting to update my SynScan V3 Hand Controller from V3.08 to latest version. Handset bootloader is V1.7.
      Unfortunately I just get the message “Can not connect to SynScan hand control”. I have looked at numerous forums and tried everything that has been suggested (including older versions of firmware installer), but getting nowhere.
      I am using a Skywatcher SynScan USB Adapter (purchased from Bristol Cameras) and installed the driver from the Skywatcher website. The adapter shows in the COM ports and says it is working properly.
      I have tried different computers (Win10 and XP) with no joy.
      Can anyone help, or is there anyone in North Aberdeenshire that has successfully updated their handset willing to give mine a go (once travel restrictions, etc ease)?
      Thanks

      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.
