Imaging with the 130pds

Recommended Posts

So the clouds parted tonight at about 11pm so i thought i would have another go with my new scope, it was pretty horrendous out with it being almost day light thanks to the moon, i did however want to try and have a go at the Leo Triplet (a bit daft as i was effectively shooting into the moonlight). I did get this though, its 25 lights various exposures stacked in DSS, no Darks, battery of both the camera and me were running low. Quite chuffed with how they turned out, cant wait to get a shot at them on a dark night though !!

Awesome, especially considering the moon!

just thinking mostly on setup at the moment, mainly where i have no mount, no guide cam and no guide scope so just thinking for when i do get all my new gear soon (all i do have now is the 130-pds lol) about the balancing issue on the dec people are having, i hear that a few people have added weights to the rear of the 130-pds, wouldnt just getting the longest dovetail plate here sort out this solution? its not a bank breaker either?...

It would be good if it did, but the scope ring is already nearly against the focuser. I could move the rings to the other side but that's a little too close to the edge for me to be happy when balancing the scope. It would also potentially interfer with dew shields and things.

Me too - I've only got a few Jupiter videos on my hard drive. Need to find time to see what I can do with them.

Tried again with a Barlow - result: atrocious. Again. Seem to be unable to Barlow anything AND get a sharp video...

my 1st guided sub from M13 last night, couldnt really bang out the long subs as still limited to 1min from my garden due to light pollution, but will be heading out to the dark site next weekend, thats where the fun will start :)

Looking clear for tonight, so I think a little more Cygnus action is in order. Need to download the latest version of Artemis before going out, as there are some funky new features i'd like to check out.

Some great pictures here, impressive. Even more so for the cost of this tube.

I started with a 130P (non-pds) which I thought was pin-sharp image wise, then jumped to a 200 (GSO) - while I love it and visually it's great, for imaging it can be a bit of a lump sometimes.

I'm thinking to compliment it with a smaller PDS for imaging, that will also be able to use all my existing accessories, the mpcc etc

My question is, 130PDS or 150PDS, probably it makes sense to go 130PDS and go wider, to compliment the 200. Right?

Another Saturn, from last night.

I took out the Neodym filter (too many surfaces for the light to pass through) but stuck with the stacked barlows (1.6x in the filter thread, and a push fit 2x both two element) to give 3.2x, and an effective focal length of 2080mm. I also lengthened the duration of the clip to 2 min and the frame rate to 20 fps.

I then pushed the AVI through PIPP, and that through Registax 5.1 followed by the legendary Wavelets processing to produce this:

I think that's Titan, at the 5 o'clock position!

Here is my take on Saturn and Mars, 1st time imaging with my new QHY5L-ii

Having a play with my new QHY5L-ii (mono), 1st time i have tried imaging with it, seeing was not the greatest. took around 15'000 images (5 min), which i took the best 7'500 into the stack.

The programs i used for processing were PIPP, Registax 6, Photoshop

and i used firecapture to capture the data which i really like

@tingting

Wow thats fantastic! is that all the QHY, or do you have any techniques up your sleeve?

@Uranium235

Wow thats fantastic! ;)

@Geuse

I always feel a little bit inadequate on here!

Uranium, i feel distinctly inadequate every time you post a picture in this thread  :embarrassed:

Dont be :)

It takes time to get this far down the road (in my 4th season), as the years pass by you will accumulate gear, find your niche and have a settled imaging routine. By that time you know all the little foibles your gear has, and how to counter them.

But with this telescope for me its been more of a case of "make it work, or I'll blow your brains out!"....lol. My astro spending has been severely curtailed for time being, so I've been given little option but to get the most out of it! :)

You really do seem to have mastered it however. 

I would love to hear any tips or pointers you might have for a novice like myself??

With this particular telescope?

Well, the main challenge is the focuser - and getting your coma corrector to sit squarely in the drawtube. Simplest solution to that is to drill and tap a third hole for another thumbscrew - theyre M4 threaded, so thats a tap size you can pick up from B&Q (they do an M4, M5 and M6 kit for a tenner). Next you might have to tweak the tension of the focuser (especially if you have a heavy camera), as long as you can get it to focus against the action of gravity (ie: with the camera pointing straight up) then thats good enough. The 2" EP holder just screws off the drawtube, so its easy enough to remove and work on.

If, after youve done the above (and collimated it to death) and youre still getting a dodgy corner/side - then you have to tackle the job of squaring the focuser. But I would leave that as a last resort becuase thats where things get really fiddly.

Edit: Dont use a laser for collimation either, a sight tube/cheshire EP is all you need - the main thing is that you need to eliminate rotation of the secondary mirror.

Thanks buddy, no techniques as such lol, only my 1st time using it for imaging, i was pleasantly surprised as seeing was not the greatest but im happy for now, just need to get myself some color filters and a filter wheel some time soon :) the QHY is an EPIC camera tho, im in love with it :)

      Hi all
      This will hopefully be the new thread for all things regarding the skywatcher Az Gti mount. Please share anything you think is relevant or ask any questions regarding this stunning and very capable mount. I'm hoping that this will become the central hub for this mount and the place to come to for advice, help, information and knowledge for the Az Gti. Share your images of your mount and set up along with images captured or experiences observing with it. I've owned mine since May this year and use it with my sw 72ed ds pro, asi air pro, Canon 600D in EQ mode. Even though its mot meant for astrophotography it sure can pull out some brilliant performances. I live in a 1st floor flat and portability is key for me and the goto functionality is a godsend to setup quickly. So feel free to ask anything and other az gti owners can help and advise.

      Hi Guys,
      So I am losing my mind with this Mount. I am having the same issues. For the life of me I can’t work it out. Here is a pic of how my scope is mounted.  Would really appreciate some help as I am increasingly frustrated with this purchase.  Thank you.

      Hello. I recently acquired an Ocal electronic collimator for my new 130 PDS and the image I see when I connect it is the one I attach. I can't adjust the green circle in the circle created by the end of the focuser. Not even helping me with the offset of the program, whose maximum is 20. I don't know if anyone has tried this collimator with its 130PDS. But it doesn't seem normal. Any ideas? Thank you.

      Winter is coming and I struggled the past days with dew on my Skywatcher 120ED. I have tried to use a self made isolation dew-cap around it, but not good enough (still dew)
      I have browsed trough the forum and read about dew heaters vs. Dew shield, and figured out that I probably need a dew heater. The temperature here can range from minus 5 to minus 35 degrees celcius, but I dont think I’ll be using the scope when passing minus 20.
      My question is, which dew heating option would handle minus 10 to minus 20 degrees celcius for my scope? I am afraid that the temperature loss will make the strips not functioning well when passing minus 10 degrees, but I might be wrong?

      I guess my scooe is around 45cm circumference outside the tube.
      I am using 220V with adapters to everything else, so power is not an issue.

      I have a Sky Watcher 150 PDS and a Canon 600D I use to take images.
      I'm  looking at purchasing a Sky-Watcher f4 Aplanatic Coma Corrector for my setup. It's as much as I can afford, but wondering if its a good choice?
      One concern i have is that my scope is an f5  which this is designed for f4 but has very good reviews.
