That RASA is a beast.

 

I want one.

Andromeda 

 

RASA 8

ASI 533MC

60 seconds exposures

200 Gain 

No Filters

45 exposures 

 

I will try to reduce gain and exposure to get more detail in my next session on this as it is over exposed some, but I was still learning on the histogram features in ASIAIR PRO App. 

 

 

Pleiades 

 

RASA 8

ASI 533MC

60 seconds exposures

150 Gain

40 exposures 

 

Something I failed to mention in my previous posts is these are taken with a SkyWatcher AZ-EQ5 in equatorial configuration polar aligned using the ASI AIRPRO.  There is no guiding being used or even a finder scope at set up.  I eyeball align with Polaris and use the ASI AIRPRO app to align and focus and works awesome.

They look great but something is strange about those pictures.

There is only one mirror with a RASA or Hyperstar, so I am guessing that you are noticing the captures  are mirror image views of what appears in a two mirror system?

Horsehead Nebula, C14 Telescope, f6.3 focal reducer, 16, 1 minute frames, QHY 294C CMOS Camera, Sharpcap live stacking, flat and dark frames added, Phd2 guiding and dithering which added 5-8 minutes to acquisition time, the image has been cropped and degraded to fit in this image gallery (<500kb).  Lyle Mars

Haha. Yes, that is exactly it. I couldn't put my finger on it.

I inherited my uncle's old inexpensive 70 mm refractor so tonight in his honor I did a little lunar EAA with it. Left side is my electronic finder scope, right side is my uncle's scope, both mounted on my C8.

Man... It feels like I'm FINALLY starting to make a TINY bit of progress.   TEEENY-tiny.

I've got sooooooooooooo much to learn. (If you have ANY help for me, please share openly. You won't hurt my feelings. This is just my 6th time out. I can't IMAGINE how annoying it must be for experienced astronomers to watch me fumble and bumble along.)

I managed to capture the relativistic jet coming from M 87, Virgo A, NGC 4496.  I know there are better captures out there, but this was my first attempt and I'm awfully proud that I could get it.  It is my understanding that better results are often obtained with shorter exposures, so if the skies cooperate, I plan to try again tonight.

 

Captured on a Celestron Nexstar Evolution 8 SCT, altaz mount, f/6.3 reducer, using an ASI533MC and SharpCap livestacked 54x8" @ 450 gain.  Cropped to a size that allows to see the detail.

 

Thanks!

This was 4 days ago, my first attempt with live stack on sharpcap pro with Eskimo Nebula (NGC 2392).

As a first attempt was a mess, like riding with closed eyes, and not really knowing what i was doing but the funny thing of this is that i'm sure in the future i will see this post with a smile in my face smile.png

Just curious how long the total exposure was?
