Imaging with the 130pds

Recommended Posts

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

Enjoy your vacation!

Louise

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!

thanks, Louise.

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.

Hi all

Thought id post the below from the first clear night for quite a while !  

IC405 the Flaming star nebula.  

Canon1100D modded with UHC filter and 130pds

6 x 1000s subs with flats , darks and bias

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...

      I'm tempted to go down the route of getting myself a brand new reflector...  My friend's old Meade 114/900 is a good telescope, but I want something of my own and with a bit more light gathering power.  To this end, I've been looking at a couple of different models and manufactures.

      I must admit, the Skywatcher Explorer 130M floats my boat, as it's motorised with a speed controller.
      Any thoughts or observations?🤔

      Celestron C8 XLT + extras and SkyWatcher Star Travel 80 (ST80)
      I have a Celestron C8 with XLT Starbrite coatings. Will include the full length base plate, both visual and imaging backs, scope rings, front 8" end cap and the finder scope with it. No box I'm afraid. Optics are good and clean, focal length is huge - 2300mm from memory. This lot would cost close to £1300 new and one with less spec went for £750 on fleabay recently. Might be interested in a part exchange or will let it go for £450 collection only.
      Also, I have a SkyWatcher Star Traveler 80 - good optics, used as a guide scope - just the scope itself (does not include the barlow in the photo) - now including dovetail bar and scope rings looking at around £50 for it.
      I have decided to save up for another refractor, WO, Equinox or even toward an Esprit. However, I would also consider p/ex for an Intel NUC and/or Pegasus Astro Pocket Powerbox.
      Please excuse some of the colours - I used my astro modded 6D which was in the observatory so the "nice" purple is actually black !!
      Both these are collection only.

      I am going to buy Skywatcher EQ5 Pro Go-To mount. But, unfortunately, I am low on budget.
      So, does someone know where can I buy the cheapest EQ5 pro mount?
      Yesterday there was a low price for it (350 €), but they changed it.
      Thank you for your time!

      I found this setup in internet and make me think, with AZEQ6 GT and 2 scopes, different weights and size, without counterweight in AZ mode! 
      - I can put a MAK100mm 3kg +- and a OO VX10l  12kg +- without counterweight?
       
      Does anyone have this setup mount and already used without counterweight with two telescopes of different weights? Is it really necessary to have a balance using in AZ mode?
      The problem to centralize the object with both scopes is true? With the SW AZEQ6 GT?
      Follow the images
      a TSA-120 with 6.5 kg i think and the other with 22kg i forgot the brand hehe you can help me?

      Selling a nice portable wide telescope with great glass and a great field of view
      I have two telescopes and I'm using the 80ED more currently and so this Telescope just isn't getting used anymore
      It has a longer dovetail (originally from the 80ED) so declination balance can be reached.
      Great performer for the price
      Collection only as P&P is like £40 (Northamptonshire - UK)
      Selling to fund a scope or mount upgrade.🤔
      Selling
