Imaging with the 130pds

Recommended Posts

Thought perhaps it's time my 130pds made it's contribution to the thread that caused its purchase...

Taken on 28/29 October:

Image: 17x539s Subs in Halpha (Baader 7nm) , 21x 300s subs in RGB, + flats, darks & bias.  Stacked in DSS, Processed in Pixinsight.

Kit: 130pds, HEQ5, Canon 600d (modified) , SW Coma Corrector, ZWO 224 on Finder/Guider using PHD2

"If you see Ghosts"

Composition of the C4-NGC7023 Iris Nebula with vdB141 The Ghost Nebula in Cephei.
3hours of 300s subs from La Mancha fields in Spain (Bortle 4 skies) at Gain 10, Offset 30, Temp -10C.

Equipment the usual:
SW130PDS+AZEQ5+QHY168C+Optolong L-Pro+Baader MPCC+ASI 385MC for guiding. Captured with APT and PHD2 for guiding. As with the Pacman nebula, my main mirror shows some astigmatism, and also the collimation was not perfect.
Postprocessed with Pix.
Regards.

Mario.

Hi,

A quick update on my mount issue progress:

I found a 2nd hand NEQ6 which I've bought and got set up with the 130PDS. Hopefully it will be able to give good results as soon as the skies clear! :) The mount seems in very good shape, although there was a bit of dec backlash which ive removed. The real test will be when I try guiding, though. ? 

This is the mount next to the old EQ5.

Nice Duplet! :)

Don't you afraid camera to fall off in such a position? 
I want to place my ASI1600 like this to make a better balance.... but I AFRAID! :)

I have always found my focuser on the 130 solid and hang off my 1600 and sx filter wheel from it in that orientation.

To be honest ive never thought of it dropping off...?I suppose I could put the strap around the scope. The focuser is very sturdy, as spillage says. I also use the MPCC which is designed for this kind of focuser, so there is an indented ring around it for the focuser screws to lock into. :)

The tube will not fall out if that is what you are worried about, it is physically impossible. You just have to make sure that you have tightened the thumb screws sufficiently and it will not move. 

I hang a ASI1600MM pro and wheel from mine without any fear.

So, I added some more time and had about 5 different attempts at stacking & processing various combinations of my data. I also got hold of Astronomy Tools v1.6 for Photoshop and took matt_baker's advice on final tweaks in Lightroom.

All in all I'm quite pleased with this considering my inexperience and the (I think) quite poor raw data I had (lots of LP, high cloud, etc.).

Thanks for the encouragement and help on this forum guys!

I will be very gratefull if you could post a picture or screenshot with the parameters you use in APT to control dithering.

Hi Susaron - I'm at work at the moment but I'll try and get the settings from my laptop when I get home tonight.

Here you go! I am not an expert at all but once everything's guiding with PHD2 I have these settings in APT and set it to dither every 2 images. It seems to work for me at least. I also use a 60 second gap between exposures in APT because I used to have some problems with the dither step taking a while, but I'm not sure if that's overkill or not. It usually doesn't make too much difference when I'm on 300 second subs though so I've left it that way.

So I hope this kind of post is allowed and I'm not seen to be spamming!

I have recently done a lot of re-processing of old data using the advice of people in here. The main difference is having obtained Astronomy Tools v1.6 for Photoshop and matt_baker's advice to touch up in Lightroom as a final step. I think it shows quite a leap in the quality of the images and also made me realise just how much skill there is involved in the post-processing of the data (even more so when the data is as dodgy as mine often is... haha).

Anyway, these are all taken using the 130PDS and an unmodified Canon 550D DSLR. They are all using 300 s guided subs (with dithering) via APT and PHD. I hope you like them. I'm quietly pleased with myself :)

EDIT TO ADD: I also have some old data of M1 and of M81/M82 however the new processing hasn't been quite as successful yet. I still need some more attempts at those before I share again!

Not at all! If you are imaging with a 130pds then post away.

Do though feel free to start your own thread if you are looking for specific advice or want to show results. It's very easy for things to just get lost in these very long threads.

Hi,

Another quick update, I got the NEQ6 out in a gap between the big Atlantic showers this evening. I did a quick PA with the polarscope and then went through a 3 star alignment which worked really well. I then got 5 frames each on M33 and NGC891. Im planning to get autoguiding up and then get some proper data on 891 later this week if the weather becomes at all cooperative. 

Noise in this "target preview" is obviously atrocious, as its only 5 mins at ISO1600! :D Hopefully with 5 hours it will be better. ;) I didnt bother to guide, so there is also some trailing. I've processed in B/W as the noise is too bad in colour. My plan is to rotate 90 degrees and centre on the bright star above the galaxy to get the nearby Abell in as well.

Hi All

A recent (August) 130pds image of M33 with an ASI 1600mm-c.   

The image is LRGB with the red channel enhanced with Ha

Here's another M33. On SW 130pds, HEQ5 and Canon 600d with IDAS D2 Filter.

50x5 min subs + flats, dark and bias.

Still a bit noisy, but very pleased with it.

Nice one.

Astra Image would do a good job of controlling that sort of noise.

Double Cluster in Perseus.

130PDS, HEQ5 and Nikon D3200

48/60x90s subs + flats, dark and bias.

Was pretty windy last night so 12 subs got thrown out. Guiding was okay at best, about 0.80RMS total

It was a 63% moon, so I decided to picture this jewel box of a cluster instead of re-doing my Pleiades pic

These cloudy days I am reprocessing some of the 2018 SW130PDS "Greatest Hits", as long as I am increasing the knowledge on the tricks of PixInsight.

Here I leave you some of the pics.

Cheers.

Beautiful stuff. I'm partial to globular clusters, and these examples are prime. I repeat myself below.

      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.
