First Light 224MC (Jupiter/Europa and M3)

Recommended Posts

I have been doing visual observing since I got my 8SE about a year ago, but I've been intrigued by the possibility of seeing a bit more (at least on my laptop screen). I got a 224MC and captured some images of Europa transiting Jupiter last night. The seeing was just average and I was on my back patio in light polluted suburban skies. This hardly matches the amazing images I've seen here on SGL, but I had some fun creating them.

I followed the terrific image processing tutorials here:
http://planetaryimagingtutorials.com/

I used Firecapture to capture both Jupiter and the globular cluster (M3), stacked in AutoStakkert, then enhanced a little in Registax. I did not use a barlow for Jupiter or my 0.5x reducer for M3.  In my eyepiece with the light pollution and neighbor's porch lights, I could barely make out the smudge of M3 to center it in my EP. I was surprised it was so clear in the 224MC.

Nice shots there Jeff, I too was out last night with my ASI224MC but is was a disaster! If I use Auto Align my screen splits, so no usable footage:help:

I've ordered a ZWO IR-cut filter and will use that, along with a 2.5x barlow next time. Better seeing never hurts either. 

Steve, I haven't used Auto Align. Sorry your images weren't usable!

I took a few more images last night of Jupiter (Io/Europa) and the Moon (Apennine Mtns):
NexStar 8 SE, ASI 224MC, IR Filter, AS2/Registax/Photoshop

I'm still on the steep side of the learning curve.

The images of Jupiter I took with the 2.5x Barlow were awful. They were much better without it. I'll give the Barlow another try but I'm wondering if that is just too much magnification for my 8 inch scope.

I find I get better results with out using a Barlow. What I use is , 2 , 80mm extension tubes. This gives me f15. With a Barlow,  it seems

to magnify every thing,  including  the atmospheric distortion, as U have found out.

I managed to focus a little better with the 2.5x Barlow. Here is Io transiting Jupiter last night.

I think for such a short learning curve your doing great!

I had good but not great seeing last night. I like the Omni 2x Barlow. It is fairly short and doesn't drastically change the focus from my 7 mm EP, so it is easier to switch back and forth between imaging and observing.

This was about 10,000 frames over ~90 sec, AS2, and Registax.

I look forward to imaging Jupiter one day with excellent (5/5) seeing.

      Hi all.
      I have just bought a Celestron 18771-CGL power tank to allow me to get out to the dark skies of the South Downs with my Nexstar 8SE. This is a great bit of kit because it's so light and portable and powers the scope for hours no problem. However, I've also been thinking about getting a dew heater and the only downside of the power tank is it's lack of a second 12v output. I was looking on the First Light Optics website and they sell a DC splitter cable to allow two devices to be powered from a single output. I'm not an electrician obviously, but logical tells me if the dew heater controller is also a 12v device there should be no problem running both the scope and the heater at the same time other than draining the battery faster. Is anyone using a splitter cable in this way? Or can anyone confirm my logic is flawed?

      Hi all,
      I have been lucky enough to have been purchased an 8SE for my birthday. Shameful to admit but this was 2 years ago and my competence has not increased much. Partly because I don't get a lot of time to play!
      Every now and then, I take the scope out in earnest for some star based escapism. The trouble is, my lack of scope skills means that I dont escape very far!
      I have never got on with the hand control of the 8SE. I have watched a lot of videos and read the instructions and the three star align process fails me most times. I read a post on here about making sure that the two 'index' stickers are aligned when attaching the OTA, which I have done. 
      I have done what I can to make sure that the settings are all correct, including time, location etc. 
      To overcome these frustrations, I purchased the WiFi attachment to be used with the SkyPortal app. 
      This configuration has been a lot more successful! I manage to align the scope using three stars each and every time - progress at last! I have slewed to the ring nebula, hit Andromeda without any problems. I'm finally getting to enjoy the cosmos! 
      However, all is not perfect. I slew to Andromeda, have a 5 minute gander at it and then use the 'best tonight' database to slew to something else. This is where it goes wrong. The scope slews to the earth. The on-screen scope location cross also shows it to be pointing at the earth, yet I told the scope to go to Vega. It tried to slew 360 and I had to stop it before the eyepiece smashed into the aux cable. Why would the scope do this? Handset software out of date? Scope set up incorrectly? 
      If this sounds like a classic dumb dumb error, please let me know. I'm starting to think my scope is faulty and my lack of experience means I have no way of telling.
      Thanks to any helpful tips in advance.
      Aaron

      I know, 130PDS is not the best scope for planetary AP.
      But I just wanted to share my beginner's results.
      Both taken on 5th and 6 of May 2018, using 130PDS, x3 Barlow and ZWO ASi224MC.

      Thanks for looking

      I had decent conditions last night and took a few images with my 8SE and 224MC camera. Stacked in AS2, used Photoshop for some enhancement. I added some labels too. Thanks for looking.
