Imaging with the 130pds

700d. Annoying star artefacts; uneven star halos, two on brighter stars... I think it's the cheepo 2 element coma corrector. Planning to follow it up to the meridian tonight. If anyone could confirm, otherwise or WHY, that would be great. Cheers and clear skies.

Yea I agree. I was doing 2 minute exposures before, but I was getting a horrible gradient. I though shorter subs would get rid of it or reduce it, but it didn't. Would a LP filter help reduce these gradients?

Galen go for an IDAS LPS D1, you won´t regret, it is an excellent LPS filter, take a look to my pictures taken last month with first quarter moon.

Moreover today I have seen excellent pictures taken with the Optolong UHC filter from the Double cluster in the Spanish forum www.astronomo.org, and it seems to be another and cheapest option as it does not change the colors of the stars.

Cheers.

A bit expensive, I was thinking about buying the Orion skyglow astophotography filter. It is a little bit cheaper then the IDAS, and it seems to be recommended a lot on the cloudy nights forum.

Optolong UHC filter

Hi. I've an Optolong clip CLS for my 700d which I used to take this. It needed longer exposures, but the detail was better. I think the UHC is narrower still. HTH.

Yes the Optolong are Chinese less expensive "copies" than the Astronomiks. if you want to take a look to the transmission curves, Carlos Tapia a Spanish physicist student who works in the faculty laboratory, has characterized every filter he can find or borrowed. Take a look to his page and the comparison among the Optolongs and the Astronomiks.

Needless to say I own the UHC/OIII/CLS and an incoming Halpha from Optolong, I am actually very happy with them, the vision of the Veil Nebula with the OIII is simply astonishing

Ok thanks everybody for the info. I realize that LP filters are not magic, and that they actually cut out some detail in galaxies and reflection nebulae. But hopefully whichever filter I choose to buy, it will help my images. :happy7:

First attempt of M45 from my back garden last night since i got my mount back from repairs!

 

3 photos stacked and edited in Photo Shop, 100 second exposures, ISO 1600 

Got it more focused here than my last attempt.

My first try at the Owl Cluster (didn't even know about it actually). 

L 10 X 128s

RGB 5 x 128s for each

It was a quick grab at the end of the night and the weather was getting bad, I hope to revisit it because its such a pretty target. :)

Been watching this thread for a long time. 

I have the Star Adventurer mount for widefield with my EOS760D and lenses. 

Now looking at a telescope again for visual and AP. 

Is the 130pds on the EQ5 PRO worth the money or should I go for the 150?

For me is was worth it. The 130pds is fantastic, and is the perfect weight for an EQ5. A 150pds might be a bit too much for an EQ5 though.

Just make sure that you atleast buy the enhanced dual axis motors for the EQ5, that way you can start autoguiding when you need to.

I love the double cluster ... I  have no idea why :)

10 X 128sec each for RGB

On your left corner you have the NGC436 cluster as well, this little scope allows these wide fields.

I do use the 130PDS for visual duties as well, it is a perfect grab and go telescope for your holidays. I use an AZ4 mount along with the AZEQ5 pier tripod, all the pack fits in a sports bag.

Cheers.

There's a rumour someone, somewhere once regretted buying a 130P-DS but Snopes haven't been able to verify it.

Fine on an EQ5, I use mine on an EQ3 (with EQ5 tripod).

Thank you for that info :D

 

The more I use this scope, the more I love it! :D

      Hi everyone!
      I am looking for a good beginner’s telescope that we could enjoy for years to come. My 10-year old son has wanted a telescope forever and is constantly reading up on the sky in encyclopaedias. 
      For my tight single-mom budget, I have found two options that seem appealing (I am enclined to go with a Dobsonian over a refractor, following comments on better image clarity):
      1. Skywatcher 130mm/f650 with EQ mount (2nd hand for CA$125) including 25 wide angle, 10mm and 3.6mm.
      2. Celestron PowerSeeker 127 EQ (new for CA$200 including taxes) including 20mm, 4mm and 3x Barlow lenses, The Sky software and a 2-year warranty (and although the website calls it a "refractor" telescope, I’m pretty sure it is a Dob).
      Could you please advise me on these two options? 
      Thank you 😊

      Hi All
      I'm looking out for Skywatcher AZ4 (Steel legs) if anyone has one for sale or know of one for sale, willing to travel up to two hours from Warrington, Cheshire to collect.
      Many Thanks

      Hello, i have recently purchased a Skywatcher 150 Mak Cassegrain, i have no experience with this design, my intent is mainly visual planetary/lunar mostly, i will be swapping between my Lunt and the skywatcher on my grand polaris mount which is beefy and rock solid, should be no problem holding the 150.
      i was wondering if i can pic the brains of those who have experience with Mak's, any suggestions on accessories which are a must have? eyepiece specifications which may suit it best since it does offer a narrow FOV? I'm aware that a dew shield is a must.
      fire away and tell me what you believe should be partnered with that scope, id love to hear it thanks!!

      hi guys,
      jon from dorset here! im new into the hobby although ive always had an interest of eventually getting a telescope. I am technically minded and am a aerospace engineer by trade, so i love to do a lot of design work (solidworks mainly) and cnc machining along with assembly.
      i have a few other hobbies such as sea angling, metal detecting, photography............when i get the chance! my wife always says she imagines me walking around a beach with all my hobby equipment attached to me hahaha!
       
      anyway back to the main question of this post!! i started looking at the skywatcher 130p, discovered a few old threads  on here regarding the 130,150,200p models. Yes i know they are going to step up in quality per model, but im asking for a honest answer if i can get pretty good pictures which each of these models? i mean i could buy the 200p and goto or dual axis motors but im not sure if that is the right choice as a newbie to the hobby and i may not even like it and quit? (just saying haha) just typical of me when i was dead set on the 130p, then i click on the model range and see the 150p and 200p and so on 
      so im not looking at becoming the next best astrophotographer, i just want to be able to use my cheaper nikon d3200 to take some shots of nebula, the moon, and anything else with some striking colours
       
      ps. has anyone got any side by side sample shots from each telescope please, of say nebula or the moon?
      thanks if you got this far, i look forward to the replies
      jon

      Hello! i am seeking the help of those with experience in refractors please!!
      I have been an amateur since i was just a wee lad, i have always owned catadioptric and reflectors of many types, unfortunately short of my current Lunt LS60PT and the department store pea shooter i had as a 12 year old and my which spent way more time peering through windows in the apartment complex across the street than gazing at the sky i have NO experience with refractors. 
      This is where forums like this come in, ok this is what id like to do, my budget is around US1,200, for this i would be looking at a doublet no doubt, i would like it to be in the F5-F7 range? this would offer some flexibility for both visual and future basic AP dabbling.
      I mainly would like this refractor for planetary, lunar and double star observing, i do hear that nothing beats a refractor for these objects and I'm itching to see for myself.
      I realize that this budget will not get me an NP101 or any other triplet for that matter, but i would like the best for that price in the 100mm range preferably since id love to stretch its legs on lunar and planetary. i also own a 12" lightbridge but this is definitely not a grab and go scope which is what id love to have now, CA would be an issue not so much for visual but future photo work id like something that performs reasonably well in the CA department. 
      if anyone out there has had much experience with refractors id love to hear from you! 
      Thank you all!!!
