I set up my CPC800, with ASI224MC camera in the early hours to get some Mars images. There was cloud about but mostly Mars was in the clear.  I did not use an ADC as Mars was at an altitude of 44 degrees, but the barlowed colour images stil needed a tweak of colour alignment in processing.

Larger images are with x2 Omni barlow lens. Monochrome image taken with infrared pass filter. 5000 frame videos, best 20% processed in Registax6, and Photoshop Elements.  Mars now has an apparent diameter of 19", getting closer to its opposition size.  The South Polar Cap seems to be getting smaller.

The surface features at 0430 AM BST match well with the Mars Mapper.

      Though M101 is a relatively large target it is quite dim and this required a significant effort to get detail into its core. I took 31hrs of 30sec exposures which I then thinned down to the best 18hrs of data. Processed in APP and PS it was tricky keeping the core detail that I had imaged from blowing out.
      Lots of advice and lots of very small curves stretches was the key in the end. Hardly sharpened it much with noise reduction undertaken as and when noise just stared to appear during stretching.
      As the sensor is biased towards red, colour balancing with green and more so with blue was also necessary.  
      Taken at Gain 200 with a UV IR cut ASI224MC uncooled camera, APM107/700 scope on an AZEQ6. 
      It’s a good little sensor if you have the conditions (cold nights) and use Flats, Flat Darks and take Darks every night as the sensor temperature varies being uncooled. For info, I found it ran at about 6 degs above ambient once it was steadily running subs off. 

      Hope you like it.

      Hi all,
      I am brand new to imaging and this is my very first set of images using the ASI224mc attached to a Celestron 130EQ scope. This scope has mixed reviews as it has a spherical mirror and I had little hopes for it. But considering what I have managed to get with just around 8mins of data, its looking promising. 🙂
      This image is of M81 Bode's galaxy using around 100 exposures of 5sec each. These have been stacked and post processed in SIRIL. No darks or flats have been taken. Still new to this aspect of it ....The images were captured using Ekos. Any tips on how to improve the image are welcome !

      Here is a pretty view of M82, taken on 12 Dec with 102mm f5 achromat, ASI224MC camera, SLT mount.
      Live stacked, 16 frames, total 138 secs.

      Here is a live-stacked EEVA image (14 frames, total 174secs) taken with 102mm f5 Startravel achro & ASI224MC camera on SLT mount.
      The 9th magnitude comet is the smudge toward upper right of the frame.  It's small and dim.

      Another Mars image ... in this one I have managed to record Olympus Mons which did not show in earlier images I made of the same longitude.  The seeing seemed good, but the sky was hazy and cloud-free as I set up. By the time I was ready to image, some cloud had come over, and instead of clearing it developed into 100% cover and an unexpected heavy shower.  As I was dismantling the now very wet telescope the sky cleared again offering a tempting view of Mars so I put all the bits back, aligned on Mars and took a series of videos.
      Kit: CPC800, ASI224MC, ADC.   20% of 5000 fromes, processed in Registax6.  I also tried a x2 Barlow but those images did not turn out well - looked out of focus.
