When entering July, it marks the 1-year operation of our remote observatory, 100% personal site and maintained by ourselves. When doing remote imaging, the data quality is so good that what I only do is collecting data and data. I only do LRGB imaging currently. Sometimes I blend with Ha. Most of the time, Ha is not necessary. I count my images, typically 2 images per month and 20-24 images per year. I usually spend 20-25 hours on one target. 10-15 hour L in bin1 mode and 10 hour RGB in bin2 mode. I use RC8 and TOA130 as a dual setup so that I can switch between wide angle and long focal length. The cameras are old but they still work very solid. During remote imaging, SNR is the most important thing. We just need data, more data. I am still waiting for my replaced Tak E160ED and may potentially upgrade my 8-inch RC to a 10-inch CDK. For Epsilon, I can get a faster aperture. For CDK, I can get a long focal length. Most of the time, RC8 shines but I still think I can obtain more detailed images at our site.  

 

Originally, I went to my site once a month now I can reduce frequency to once every two months. I have talked about our observatory on the Astro Imaging Channel. A couple of folks contacted our land owner about building their observatory at our sites. Due to the interest, my land owner and I consider building another one in the next year by ourselves.

 

Here are the combinations of the first-year images. You can see at the beginning, my process techniques are a little bit aggressive. Later when entering the galaxy season, I think I have found a better processing workflow. Anyway, I am not good at post-processing, still need to learn. Overall, I am very pleased of the 1-year operation. I hope at least I can run for the next 4 years in order to complete my image list. It is time for me to print some and hang them in my home, send to friends and make a new calendar for the next year.

The first image is just showing how good collimation of my serviced TOA130. When it is paired with 16200 and 35 reducer, the reducer provides excellent results.

Then I tried to image some dark targets. They are hard. I need to add more data and re-process them.

Then I imaged M45 and NGC1333. Two on my list and required by my collaborators. You can see M45 has so many small galaxies behind.

I started my first mosaic project during last October and finished until this February. I first processed two famous objects then completed the rest 2 panels. More than 100 hours on this project.

I was fortunate to capture the Comet Lenard with M3 last December.

Outstanding results from your first year at the observatory!  I'm not sure your processing needs all that much work - it looks top-notch to me.  Congrats, and best of luck in Year 2.

My friend's RC8 jumped in last December. Perfect for galaxy season. I cannot imagine I have so many galaxies finished so far.

My friend likes galaxy group, so do I. RC8 is powerful, however, it does suffer from mechanical stability. Sometimes the collimation needs to be re-adjusted after 2-3 months.

Now galaxy season is done. I am back to TOA130. RC8 can rest for a while, although there are still some interesting targets for it during summer and fall. However, my 8300 cannot cool down a lot during Texas hot summerbawling.gif

A quick note on the RC8… mine would not hold collimation at first. I traced the problem to the light baffle that also holds the primary was loose. I carefully reached in and snugged it. Now all is well. The collimation holds perfectly.

 

Wonderful pictures!

Thanks for the advice. If I put RC8 for mobile imaging, each time I can tune it very well. Now this is remote, the temperature from winter and summer is a huge difference. Potentially it will suffer from material expansion and shrinkage. Anyway, the overall results are acceptable for megrin.gif

You've got some pretty spectacular images. I'd say your first year was a success :).

All of those are great, but that NGC1333 stands out for me, as I know how faint it is!  Impressive work!

Thank you. NGC1333 is hard, because I have gradient on all LRGB subslol.gif
