Imaging with the 130pds

Recommended Posts

Depends on the coma corrector. You'll have to try it and see!

Enjoy your vacation!

Louise, 

just tested yesterday the cc and it helped with the missing chunk problem.

i have another doubt, since my finderscope is in the mail limbo. can i use the asi120mc with the 130pds and use phd to help improve my PA and then do unguided shots?

thank you

Hi

I guess you could in theory! But I think the small pixel scale and small fov might make it difficult - try it and see!

hiya ,

im new over here i left a post about who i am,... in the welcome section.

i'm quite new to AP . but i purchased yesterday a 130PDS :grin:  . to keep your army growing over here. next month the unmodded canon 1200D follows with CLS filter. i got an 9X50finderscopeguider with asi 120mc from a previous rig. from than i hope i can start making some nice pics as well.

oh btw if people have balancing problems, lots of manufactures may hve solution if you modify a bit

like this for example you can hang this weight at the very end of your dovetail , easy

sorry for being a belgian site but you can google it for your scope-vendor as well i guess.

several people including myself use ankle weights attached to the OTA to counter balance the camera etc.

i did get some first light pictures with the 130PDS and canon 1200D

the result is on:

http://www.astrobin.com/223406/B/

still lots of room for improvement.  need to learn making flats , to buy a coma corrector and maybe some better collimation,...  but i'm just starting with AP since end april 2015.

Yep definitely a corrector required, and taking flats isnt so bad - all you need to do it point it at a PC monitor that is displaying notepad. However, one tip is to diffuse the light coming from it with a sheet of A4 or A3 copier paper - which also dims the light so you can use a longer exposure time (flats with too quick a shutter time dont come out very well).

Nice tip! Paint in full screen mode eliminates scrollbars and borders too.

First light with my nice new 130PDS (and first image after almost 2 months of rain and wind and clouds.....). Keeping it simple for its first outing, so 25 x 120 seconds with Canon 450D, aligned and stacked with Nebulosity and then levels, stretching and curve tweaking in Photoshop CS2. Pleased with the result, although looking at the other images I have a lot to learn...

I know that feeling...

Excellent work, by the way!

Nice image, Nigel.

I have found that the pleiades need a series of long exposures (say 5 minutes or so) to get all the faint nebulosity around the bright stars. I found it to be (a bit like M42) not the easiest to get it right due to its high dynamic range.

this is my first try with guiding.

7x130s iso 800, i forgot to take darks. edited in photoshop and did some noise reduction too. i'm still not using the comma corrector, will try soon to see if the spacers are needed.

quite  happy with it, thanks.

IC405 the Flaming star nebula.  

Canon1100D modded with UHC filter and 130pds

Please excuse the coma.

I have recently acquired an Atik 383l+ mono and hope to be up and running with that soon - although its a steep learning curve !

Very nice, but I think there could be a lot more detail in there if you relaxed the black point a little.

Hmm, yes you're right!

Is this one better?

Hello to everyone!

This thread is the reason i bought my 130pds, so i have to post my first two photos taken with it (and my first ap photos in general). 

A couple of words first... 

I wanted a telescope for years (and stop observing through my grandfathers "Jack Sparrow style" old 2" refractor!) so last June i decided to buy one as a present to myself for my birthday. My choice was a SW 200pds on a HEQ5Pro mount (following the advice of a friend of mine). I spent most of my free time in summer observing (and learning how to use an eq mount) and i soon realised i wanted to start capturing the things i saw... I started surfing the net to learn what else i would need and i saw this thread. I was astonished by the results from a relatively cheap telescope! The fov was so wide i could capture the entire Andromeda galaxy!

So after i purchased an asi120mc for guiding-planetary imaging, a Canon 600d (which i Baader modded following Gary Honis' excellent instructions) ,a SW coma corrector (all used) my next target was the small SW newtonian. I also bought an Optolong 2" UHC filter a month ago.

So these are my first photos from a place outside Athens as the light pollution in the city lets you see a dozen of stars max. The processing (i have to learn this too...) was done by a friend of mine in the Greek astrovox.gr forum.

Before these photos i have spent hours and hours online learning the best settings for my setup and how to use the equipment.

I used Byeos, phd2, DSS and my friend processed them in Pixinsight.

Wow! How the heck did you get IC1805 that good without the stars over powering the image? I have tried with 600s exposures too but the stars are so many and bright!

Martin, i have no idea! I simply watched the histogram in BYEOS and it was pretty good at 600s, maybe i could try even more (700-800s) but i wanted at least 10-12 light frames and my time was limited.

I suppose the filter has done a very good job in boosting the nebula's contrast...

      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.
