Just got my first light with the rasa8 after waiting 6 months for all the pieces to my new rig to arrive. Everything went well, but it was cold Saturday night(-10C), and I’m pretty sure it messed with my scrawny cheap USB cable I had going to my mount. I could plate solve my images in Nina, but the command to sync with the mount was failing, even though it was working before, when plate solving was failing due to me forgetting to change my FL from last session.. long story short, I ended up having a good session other than the fact I was not aiming at m81 + m82 and friends due to USB failure. I was almost 3 degrees off in RA and almost 2 in Dec. according to plate solving. I expected to get a nice pic of a star field, maybe a couple tiny back ground galaxies if I was lucky.. well, I think I lucked out and picked up random IFN from the m81 and m82 region.. I also must say how blown away I am at how good the image looks compared to my last ones with a dslr as far as just how clean they are. This is the first one of my pics I can zoom in really far to the pixel level and still see a smooth image. If someone can indeed confirm that this is IFN in the image and not noise or some other artefacts that would be amazing. Anyway, thanks for taking a look!
334x60sec. Exposures(3hrs, 54mins)
50 darks, no flats(haven’t gotten a dew shield yet)
Gain 121, offset 30
I blew out the brightest stars, so I’ll have to ease back on the exposure times and/or lower gain to full dynamic range mode even though they were only a min each lol. I’m used to my f/10 sct, this light bucket is a joy to use. I was so afraid of tilt issues after reading on forums LOL. I’d highly recommend it!
The mount has also been fantastic. Up until now I’ve only used either my canon 60d/135mm lens, or the asi294/astromechanics ascom adapter/135mm lens on that mount which is a tiny load, but it tracked perfectly none the less. I noticed no difference with the rasa8. Solid as a rock. The ipolar does a good job with polar alignment as well as my image has no discernible drift from first to last exposure over a 4 or more hr period. Anyway, that’s all I got!
Clear skies everyone!! And may the kraken keep away from your imaging rigs!
I will post a full res version and the raw stack once I’m off work.
