Popular Post silentrunning Posted April 27, 2020 Popular Post Share Posted April 27, 2020 (edited) Another great night last night though I fear that may be the end of a good run of astro friendly weather. Finished at 430am not long after the cameras started picking up the morning glow. Crazy haven't been to bed before 3am for the last few nights. Most of the earlier part of the session was spent acquiring 3 hours of Lum data on M100 which I have yet to process but the last couple of hours was spent on M56, a lovely globuler in an incredible star field in Lyra. This is 25 minutes of RGB binned at 1x1. I was to tired to get flats last night but will hopefully get some regardless of the weather this evening when I stand a chance of getting the camera back to -20. Surprised how well this has come out without any flats. I've got used to imaging galaxies and having to stretch the image to the very limit, this was a nice change in that respect.

Clive Posted April 27, 2020 Share Posted April 27, 2020 Looking at that (albeit on my phone) I'm not sure I would even bother with flats 😆 silentrunning 1 Link to comment Share on other sites More sharing options...

We'll see how it goes. One thing, it will allow a wider crop though not a lot got chopped in this edit. Link to comment Share on other sites More sharing options...

+Graham Posted April 27, 2020 Share Posted April 27, 2020 Heck John that is a lot of stars. Could do with a run down of the kit you are using. silentrunning 1 Link to comment Share on other sites More sharing options...

Hi Graham Thought it was all in my signature but I hadn't set it up, DOH. Just corrected that. It's the setup I've been using for sometime now. You are certainly familiar with the back end of it as you built one hell of an adapter for everything hanging of the back that has worked perfectly to correct the design flaws of the original arrangement which had the focuser and everything else effectively connected to the mirror cell. This would distort the image to different degrees based on the elevation of the target object. Your solution fixed all that. The camera is a QHY11 which I acquired a few years ago second hand, it has a massive chip which has never reached it's full potential due to the long FL of the GSO 12" RC scope (2400mm), although this is reduced with a 2.7" Astrophysics FF/FR (~1950mm). This is connected - via another adaptor that you build - to a 2" SX Filter wheel. The camera would be awesome for large nebula etc if it was connected to a wider field scope. The previous owner had such a setup and the images he acquired of these objects, which are to big for my FOV were simply astonishing.Guiding is via an SX OAG connected to the filter wheel. The whole shebang which I think is about 38kg is mounted on an EQ8. My obsy is a converted potting shed which works brilliantly. Can't remember the set up I had when you visited a few years ago, it may have been the one described above or it may have been the pre obsy EQ8 - belt converted by you. A couple of pictures from the obsy web cam.... Link to comment Share on other sites More sharing options...

Clive Posted April 28, 2020 Share Posted April 28, 2020 I suppose that's what you get for using social media and accepting website cookies, they just push something that they think you may be interested in. After your video of the scope going to bed, I got a video clip of the Led Zeppelin concert on my phone (but just a lot of garbage on the PC)!

I had visions of my video clip being hijacked by a sound track of Valhalla! Not necessarily a bad thing. Link to comment Share on other sites More sharing options...
+Glafnazur Posted April 28, 2020 Share Posted April 28, 2020 Nice set up John, I really need to convince my wife that we've got spare room in our garden for a small observatory. silentrunning 1 Link to comment Share on other sites More sharing options...

Thanks Dave, goers without saying really but a permanent set is a genuine game changer. Link to comment Share on other sites More sharing options...
