Another First Saturn

Recommended Posts

I thought I'd have a go at imaging Saturn last night. The results aren't very good but it's nice to even have the opportunity to image something!

Any tips on how to achieve better? Not sure what's limiting me most: seeing / aperture / settings / magnification??? It shouldn't be focus because I used a Bahtinov mask + Bahtinov Grabber... but I had to use a lot of sharpening!

150 PDS

Televue 2x barlow

SPC900 + IR Cut

Settings: 15fps, max shutter, high-ish gain, no gamma.

Thanks!

this is actually a very nice start! the focus seems o.k. Yes a barlow will definitely help (try to reach f/25 - so you need a x5 barlow although x3 will do a nice job too)

You didn't mention if you used the wavlets, after the wavelets usually little sharpening is need if at all.

Thanks

Thanks Dror,

Yeah I did mess around with wavelets, but found it looked better with a little more sharpening afterwards in PS. Was hoping to capture the Cassini division but only have hints of it - think I need more focal length as you say!

Nice image Lewis,

I had two nights of clear skies recently - only ones in the last couple of months! :mad:

Anyway, the first night I couldn't even find Saturn when I popped the web cam into the mirror diagonal, so I gave up and just observed it for a while. On the second night I eventually got the planet in the camera after about 20 minutes of trying, I started the capture which ran for about 20 seconds and then my laptop froze! When I tried to load what I had recorded the file had obviously been corrupted as it wasn't recognised by any of my video programmes!!! :angry5:

It's not good for your blood pressure this game! :grin:

lol, all good fun isn't it!

I spent a long time trying to get Saturn into my FOV too, not realising my finderscope was way out of alignment. For about half an hour I was convinced I just couldn't find focus. Eventually I got some sense and popped an eyepiece in, re-centered... sorted within 30s! :rolleyes:

Then, about 5 minutes later, Saturn disappeared behind a neighbour's house!

Aim to get it as accurately centered as you can with a 6mm eyepiece and then swap for camera .

Turn the Gain and Exposure up in your capture software and then adjust focus til you see it .

Defocussed it can be nigh on impossible to spot even if it's bang on the chip.

Yea, I think focus was my problem initially. I didn't realise that swapping the ep for the webcam would mean quite so much refocussing! :rolleyes2:

I too had knocked my finder scope so I had lined it up on our local church weather vain finial earlier that evening with a 6mm ep and x2.5 barlow in the main tube, so it was as centred as I was going to get it. Didn't stop the laptop from locking up though.

Oh well, I hear we might get a summer in September so I may get some clear skies...in about 3 months!!! :Envy:

Dorothy and Toto just blew past me here so no chance of getting out tonight with the scope! :embarassed:

      Hi guys,
      I am a newbie on this forum, this is my first topic here but I would like to show you my recent planetary imaging results. I started to catch the planets with a dedicated planetary camera last month but never thought that a small 4" Maksutov can show such small details. The equpment I used:
      SW 102/1300 Maksutov 2.25x Q-turret Barlow lens QHY5L-II color camera EQ-3 GOTO mount All the images were taken on differend countrysides in Hungary. I hope you will like it
      Also, please share your images taken with similar OTA, I'd like to learn some tricks from others as well  
       
      Jupiter's 15 minutes of rotation. Captured with Firecapture, processed in AS!3, Registax and WinJUPOS (2020.08.21)
                                                                          
       
      Saturn, 1 hours stacked with AS!3, processed in Registax (2020.09.05)

       
      Mars, 3 hours of rotation. Captured with Firecapture, stacked with AS!3, processed in Registax. (2020.08.22)

       
      Mars again, 5 minutes stacked in AS!3, processed in Registax. You can see also Olympus Mons and Arsia Mons next to the terminator  (2020.09.05)
       
       
      Finally, a result of a Hungarian star party where I learned how to use properly my equipment  This time I borrowed an ADC for Saturn.

      I'm trying to get a photo of Jupiter and Saturn with my Nikon D3000 DSLR but I can't get anything clear. I attached the kind of photos I'm getting with my camera. They end up being too bright and no distinguishable features show up. Is it even possible for my Nikon to get photos of planetary objects like Saturn and Jupiter?

      Just had the MOST amazing observing session of my life!!!
      I am staying / living in the Blue Ridge Mountains at the moment and am blessed with very dark skies.
      About an hour after sunset, appx 9.50pm, I saw comet NeoWise motoring - could literally see it moving as I watched - upwards in to the NW twilight and then watched (10x50 bins & Cassie)  it disappear  over the top of the mountain.............. completely, totally, surreal. I saw comet Hale Bopp in 1997 in London and whilst that was spectacular, what I saw tonight was just absolutely surreal. Most comets 'just' appear to hang in the sky, whereas I could actually see Neowise moving. From coming into view to disappearing over the NW horizon must have taken only 20 minutes or so. There were a lot of helicopters up over the mountain watching it.

      Then, at about 10pm heading north was what I believe was the ISS. I've yet to check for sure but it was nearly as bright as Venus and moving slower than a satellite.
      Then I saw numerous DSOs, globualr clusters and nebulas. 
      Then turning to the SE I saw Jupiter and Saturn, Unlike the other evening when the image was very blurred (atmospheric turbulence?) tonight's images were clear and beautiful. Could clearly see Jupier's cloud belts and the 4 biggest moons. (108x  9mm + 1.5 Barlow)
      Saturn was the best I've ever seen him. Crystral clear ring definition and I am sure I saw one of his moon at about 7 O'clock to his position - maybe Titan? 
      I'm not an experienced astronomer (telescope wise) but I have followed this subject all my life. I don't know much but I do know that not many people will ever get to see what I did tonight all in the course of 2 hours. 
      I am very blessed and thrilled beyond belief!!!! Everything tonight viewed through my trusty 5'" Newtonian, Cassie 😍
