New boy in the skies


Recommended Posts

Just got my first scope had a couple of casual looks around the sky this going to be a bit of a learning curve. Would like to get into Astro photography eventually. 

The ccd cameras are hugely expensive so would be going DSLR route. From what I can gather  I would also need a tracker other than the Audiostar system that’s currently part of my setup any suggestions as to which one would be helpful. 

Only ever used a DSLR on a normal tripod up to now with normal lenses. Here are few  that I have taken in the past. Would like get some moon shots, galaxy shots in fact anything st all really.

Some cracking images there Grommet (sorry, I mean Mick!).

What you will need for astrophotgraphys is a driven equatorial mount which will track the movements of the targets accross the sky as well as keeping the orientation of your telescope consistant with the target.

I don't know wheter your mount is an EQ (equatorial) or ALT/AZ (Altitude and Azimuth). The issue with ALT/AZ is that the telescope and therefore the camera stays on the same plane in exactly the same was as panning and tilting on a camera tripod. The movement of the styars accross the sky follws an arc so the telesope needs to move from east to west and also 'twist' so that the target remeains orientated the same way for the whole capture period.

A basic EQ mount would be a EQ3/2 like this which can be motorised-https://www.firstlightoptics.com/skywatcher-mounts/skywatcher-eq3-2-deluxe.html

Other optios are available with bigger capacity and slicker drives such as the HEQ5- https://www.firstlightoptics.com/skywatcher-mounts/skywatcher-heq5-pro-synscan.html

many options exist either side of the HEQ5 price point.

For straight DSLR astrophotography there are mounts like this that fix to your tripod- https://www.firstlightoptics.com/skywatcher-mounts/skywatcher-star-adventurer-astronomy-bundle.html

Good luck and enjoy.

Thank you chaps and chapesses think I will buy a wedge as my mount is Alt/Az l have eq mount that is motorised but have not got round to using it all's I will need is a dovetail to mount my camera on, with the static star trail stuff will I still need to take lots of say 30 second images and use star stacker to process the images. I will be limited to f5 with 440 mm of reach iso 1600 or 800 full frame. Think this should do assuming I manage to set up the mount correctly seems like a lot of messing around as far as I can see but the only way to keep things in registration. Could still use the lx90 as is for shorter exposures. Just got to learn to walk before i run.

      Hello.
      My name is Luiza, I am a student of Computer Engineering in São Paulo, Brazil and I would like to ask for your help.
      As yesterday was the super pink moon day, I, at about 22:50, decided to take several photos of the moon using my phone and my non-digital telescope. And, analyzing the photos now, I realized that in some of them there are certain objects that I can't say exactly what they are. Could you help me identify them, please? I am not sure if they are satellites, ISS, Hubble, etc ... and I am very intrigued by themphotos.rar.
      P.S: the objects are in the lower left corner of the images

      Hi. Its been 12 days of lockdown here in New Delhi, India. Gave me some quality time to spend on my childhood hobby. After a long time, I pointed my 10" Dob towards the Moon. And surely it does not disappoint. Its always a pleasure observing its surface. Observing it through eyepiece was a hair raising experience as I moved from 25mm (48x) to 6mm with a 2x Barlow (400x). Later I connected my dslr to the scope and took some quick pictures attached below.
      Also took a video. Here's a link to my google drive. Please excuse me for the background noise that is there in the video.

      Due to a telescope upgrade I now have available my LX90 and a lot of accessories to go with it. The OTA itself has been upgraded and improved a lot it has had the following upgrades:
          Thrust bearing upgrade to smooth focusing
          Screws replaced with stainless
          Bob Knobs collimation knobs
          Flocked tube to improve image contrast
      The scope comes with all the standard accessories: 
       
          Meade 8x50 Finder Scope
          Meade 26mm super plössl eyepiece
          Meade 1.25" eyepieve connector

          Meade Autostar hand controller and external control and update cables
          Meade field tripod
          and manuals
      Plus having used it for imaging and having de-forked the OTA to use it on a German Equatorial Mount it also comes with the following extras to allow a variety of options for both visual and imaging options:
          ADM Counterweight and accessory rail for 8" SCT
          ADM Losmandy Dovetail for 8" SCT
          Star Sharp Bhatinov Mask

          1.25" Light Polution Filter
          1.25" OIII filter
          Power supply for Meade LX90
          Meade equatorial wedge with adaptor for the LX90
      The scope has now been put back onto its forks and tested. If you want to see detailed photographs of everything then please have a look at: 
      https://drive.google.com/open?id=1Gp5a1yf-3ypq_lzYzvVGi9l_ug03mNZb
      there is even a short video showing the mount working there. As for the capabilities of the scope you can see a few examples of images taken with this scope at:

      there are even more on my astrobin page:

      Unfortunately due to the size and weight of the scope, the amount of kit I'm selling and lack of boxes, I can only do collection only.
      I'm looking for offers around £1000 for everything. But I'm willing to consider splitting if you don't want it all, just let me know what you are interested in and we can work out a price. For just the scope and standard accessories, I'm looking for offers in the region of £700, so for just £300 extra you are getting a lot of options. A quick add up of what this has all cost me new comes out at around £2500.
      I can accept payment via bank transfer, cash or pay-pal (buyer covers fees)
      If you have any questions please do not hesitate to contact me.

      Hi All...
      I am wondering if anyone can help me?
      Just starting out imaging with a Meade LX90ACF 8". Whilst I am not new to this, I've changed my game from CCD to DSLR and am on the learning curve again! I am getting a strange reflection when I image anything bright, ie a star. Please can you have a look at the image and see if you have any tips to not get this crazy blue swirl... whilst it is pretty, it is clearly not anything in the sky and will always be on the image somewhere.
      Lunar or planetary.. not a problem... just the bright stuff (whether a short or long exposure). I've tried a canon 350d and 1300d.. both the same! I am still playing with my alt/dec % so am still getting a little star trail on this 3 min exposure, not worried about that!
