Imaging with the 130pds

Recommended Posts

Thank you, Louise

Didn't know they had different names. Gonna make a search fo it.

that brazilian site you gave me is the store i bought my current telescope and it's a very good store, i contacted them but they don't sell it and are not importing at the moment.

For the moment i think i'll pass on the coma corrector right now as i'm still learning, maybe later when i get more demanding :)

Yeah, I don't have a coma corrector for mine yet - not even tried it visually at night yet either! Weather looks like being cloudy for another week, at least. I fear February will be write-off just like January was :(

Thanks again Uranium. I have gone with the ST80 and dovetail so that I can use it with the LX200 when the target is appropriate (and my skill levels reach a suitable level!) Order placed with FLO so can now get excited! Thanks for your help of which I will no doubt be seeking more at some point!!

I was on the fence between 130p and 130 pds, but this has settled it for me. 130pds all the way as my first starter

I know that Uranium has actually sawn of the ridge of the skywatcher coma corrector in order to put the whole camera setup further inside the focuser and thus reduce the length the focuser sticks into the actual tube. Would there be another coma corrector fitting the 130 pds where you wouldn't need to do that? Anyone has one?

After a long abscence I've finally managed to start with NB imaging...

Moon was up - but with Ha you get quite a good result as opposed to my previous Canon attempts... lol

Anyway, judge kindly, I somehow need to figure out how to prevent stars from bloating. As well - On the stars right hand side I can see an indentation which I think stems from the focuser tube jutting forward into the scope tube.

Anyway - now I'm waiting for clear skies to add OIII and SII.

Oh, and I've realised that by imaging several nights and adding more images you de facto are making your final image smaller, because you will never be 100% spot on with your subsequent images, hence cutting off at the edges in stacking. So I guess - looooong exposures is the way forward to increase image size... sigh... On the bright side (even though this image below is 500s exposures) I did manage to do one night of 1000s for the first time with SII. With the moon nearly full, you couldn't really see anything unfortunately. And, now all these images are stuck on a USB stick that suddenly decided to pack it in... uff

Congrats on taking the plunge and going Narrowband. I've just hit the second stage in the prcess by modding my DSLR and using a UHC filter to cut down light pollution. Just trying the modded camera out tonight. Started with a few subs of the California neb to test out the Ha gathering capability and am currently imaging M101. Yet to process these.

Look forward to see your finished Elephants trunk - looks like a very good start - it must be quite exciting producing CCD images for the firsdt time ! The amount of detail revealed is amazing. Great to see you can use the technique to defeat moonshine - that really increases the time available to image DSOs ! Great way to fight the dreaded light pollution as well. Only disadvantage I guess is the length of time spent imaging by adding in the different wavelengths over a number of sessions. I use Astrotortilla to keep targets central although there must be an easy way of getting the camera in the same position every time to avoid too much cropping when stacking !

I feel I need to muck about some more to drag out the last dregs of performance from my DSLR now I've had it modded before I feel I would be ready to get a CCD - although hopefully not too long !

Cheers

I use AstroTortilla too, but slight differences b/o movement or camera rotation already make a difference. In particular if you're stacking like 100 images...

Guys, how do you process your stars? Mine seem to come out fuzzy??... Tried star masks but somehow it's not quite right and sharp.

The Baader MkIII will fit the bill. It all screws apart so you can break it down to an M48 thread, it offers no redcution factor - but the field is good.

Bloomin 'eck Uranium....I hesitate to post, having seen that last image.

To hell with it....hello folks, this is my first attempt with a modded Canon 100D with Astronomik CLS clip filter, using the Skywatcher CC, sitting on the 130PDS, sitting on an EQ6 AZ GT.

27 x 210 seconds with darks, flats, bias and dark flats. Unguided.

Have managed 4 minutes unguided but playing safe. Totally incompetent but keen as mustard. Cheers.

Hi all, this is my 1st process of M81 & M82, i cant ever seem  to get to a place where i am happy with my images, im way too fussy....i know what i want to do, just my Pixinsight skills are not up to what i need to do, and i try to over think things in processing which really seems to bog me down, any way this is my 1st process of this target....


 


This was taken at Turf Hill on Saturday 21`st Feb, it was a good night collecting the photons, how ever i had quite a lot of problems lol, but hey ho it would not be astro imaging if there were no problems  :D


 


i ended up with.....


16 x 10min light subs @ ISO800


50 flats @ ISO800


50 darks @ ISO800 (taken from my darks library to match light temps)


140 bias @ ISO800


 


thanks for looking


 


clear skies

Looks very good tingting, really sharp detail and good colour balance. I'd be very very pleased if i had done it!

Very good. Both galaxies have high dynamic range with cores which eadily blow out but here they are nicely controlled.

It might be of no help and I don't do deep sky as I can't afford a proper camera so I just webcam planetary, I stuck some sticky back wheel balancing weights to my scope for when the webcam is in and the heavier eyepiece, I only have a beginner scope but they work pretty well. I guess you could put a few on a Velcro strip and put that on the scope so they come off easy.

The 130pds is a scope I hope to own one day and of course a camera that doesn't have (bridge) at the start aha

I can't wait for mine to arrive.

Hope it doesn't get stuck in customs here :)

I've had mine for nearly 6 weeks but not had a chance to use it yet!! :( I'm going to set it up with a solar filter tomorrow in preparation for the partial solar eclipse on the 20th March :) I'm sure you'll enjoy imaging with yours :)

please post when you catch it, it won't be visible here.

the 130p-ds will be a great fun and i'll keep using the 114p for visual with my little niece, an astronomer in the making :)

      For sale is my beloved but now superfluous to requirements HEQ5 Pro for £700
      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

      Hello,
      I know you've seen these questions a lot (unless your new) but I'm struggling a lot on if I should buy a Skywatcher 250px (10") or 200px (8") (dobsonians). I have a 5 inch and i'm looking for a big step up for noticeable changes. 
      Thank you

      Hi All,
      im totally new to this and have been getting setup over the past 3 months. I’ve purchased a Skywatcher 150P on a EQ3 Pro mount. 
       
      I have a 2x and 3x Barlow with 10x and 20x eyepieces. I’m trying to view and photograph Mars as it’s so bright at present and easy to see however I’m really struggling to see anything more than a bright ball when viewing and when photographing it’s just a blurry ball. 
       
      I have a canon 700d DSLR with t ring and adaptors  
      can folk suggest what combination of Barlow / eyepiece would be required to view Mars in all its glory and possibly lens and iso/exposure settings to get some nice shots too please. I’m aware I may need to stack and am tech savvy so this bit should be ok. I just can’t seem to get anything at present to process.
      help!! 
    • By Astrid
      My 200P just arrived and oh my God... I have been trying to wrap my head around the mount for 4 hours.
      The manual didn't really help so I decided to go on youtube, but again, I didn't find any good and detailed videos so I decided to ask here if there is any video or perhaps blog post that might help me set up the mount. 
      Thank you very much! 
      *by the way, is the EQ5 supposed to have slow motion cables? I only got 2 knobs (not cables) and I'm not sure if there is something missing or not... sorry, this is the first time I've used a serious equatorial mount or telescope. 
      Thank you very much!

      There’s a new kid on the block now, so it’s time to move this brilliant scope onto another happy owner.
      Bought new from FLO just over 2 years age, it’s produced some awesome image - shown below - all taken with this scope and an ASI294 camera.
      I’ve upgraded the focuser to an OVL model, and the difference from the standard one is immense. Runs smooth from one end to the other, and has no problem holding a lump of a cooled camera or a DSLR without slipping. It also has a standard 2” connector.
      Also included is the Skywatcher 0.85 focal reducer/flattener with 2” adapter, so swapping out the camera for the eyepiece is a 2 second job.
      The optics are all clean, bright and scratch-free. There’s a piece of Velcro on the tube, where I used to have my ASIair V1 stuck on. Apart from the usual bite marks on the dovetail, it’s in excellent overall condition.
      The standard SW 9x50 finder scope, 28mm eyepiece, a couple of adapters, and diagonal are all included, also comes with the aluminium case.
      This whole outfit would cost you £842 plus delivery, to buy from FLO today. It’s yours for £525 delivered to a UK mainland address.
