wornish

Tried again last night. This is with 2x Barlow, 12 ms exposure, gain 151.  Think its a bit better but still not happy.

best 5% of 15000 frames.

I am using my Celestron Edge HD 9.25.  Focal length 2350m.  No Barlow.  No drizzle.

I used Sharpcap to do the capture in  3 sessions each of 5000 frames joined in PIPP using the Join function.

Stacked in Autostakkert 3, Wavelet sharpened in Registax 6.  Final tweak crop and and enlargement 2X in PS

Any advice appreciated.

I have the 290MC and find the images I take of Jupiter to be very noisy.  Even if I stack thousands.

Or is it just the usual UK seeing issue?

This is the best 5% of 15000 Frames

Are you certain the USB ports on the laptop are working?

Blimey I would not be happy if that happened to me.   Only suggestion is disconnect everything and try each piece of kit separately to see if it works.

Kstars/Ekos for selecting targets, focussing, plate-solving, sequencing, capturing and guiding, oh and Dome control. Its free and runs on Windows, Mac or Linux systems.

Astro Pixel Processor for stacking

PIxinsight and PS for further post processing.

If portability is your primary goal then have you looked at the RST-135.  It is highly portable and can carry 13.5Kg load with no counterweights.

Only downside is its not cheap!

Just tried your link and the download works fine.

here is version 3.16 for windows.

Its a very special image, it would be fantastic to see Jupiter up at 45 degrees altitude.

We can all dream.

Updated mine today, missed that new feature thanks.

Excellent detail.

I have a similar setup using a Raspberry Pi4 on my mount running KStars to control everything.  I boot and run the RPI from a 100GB SSD attached by the USB3 port which makes a huge speed improvement over an SD card

As I have to set up each time I have used a WiFi extender to allow me to be inside the warm house and control the RPi using VNC.  

I store all the images taken on the RPi and only transfer them to my iMac the following day.  It works most of the time but the connection is fairly slow and does drop out but at least the RPI carries on until the connection reestablishes.  This year I decided to buy 40 Metres of cat 5 ethernet cable and connect that to the RPi directly on the mount and run it back to a small router in my study with another short ethernet cable from the router to the BTHub tucked away in a cupboard.  The speed improvement is amazing and it works brilliantly.  Yes it means I have another cable going up to the RPi on the mount but its well with it and no drop outs.

Managed a few hours under the skies before cloud and low mist rolled in. Wasn’t able to do a proper off set init as not many stars available to pick from due to the very light nights. I can now understand why fellow astronomers don’t image or wait for darker skies in the summer, as there doesn’t seem to be any 😂. So a quick peep at the low moon was all I could manage unfortunately.

Jobs to do before Autumn - I feel like I’ve jumped off the deep end of a swimming pool whilst struggling to swim!

Recheck Lat / Long and current time?

Work out how the mount knows where it is pointing? Learn to park, unpark, set park etc.

Understand the difference between off set innit and syncing?

Pick a suitable software package for tracking / modelling the sky.

Try and polar align the mount, drift / software / polar scope?

Work out adaptors and spacing for my camera / telescope / flattener.

Buy a guide camera and learn PHD … oh the joy!

Beg for assistance from anyone that can offer assistance to a fledgling new starter 😊.

So first light of the moon taken with my phone, held up to the eyepiece. A long journey awaits possibly full of self doubt, angst and a large dollop of trepidation.

Thanks for reading.

 

Well you certainly have jumped in the deep end.

Enjoy the learning process. 

Excellent images.

Just realised this is a duplicate post, I don't know ho to delete

Excellent.  I am jealous.

I use the ZWO asi290mc it works for me. I used it on Jupiter last night  on my 9.25 see my post on here.

Taken waiting for Jupiter last night.

First go in over a year so a bit rusty.

This is a stack of the best 10% of 500 frames.

My mistake it was ISO 2000 hence the noise.

1/2500s, ISO2000, f/5.6, 420mm

Single shot - EM1mk3

The clouds last in proportion to the money spent.  

As I said in my post almost a year ago macOS Catalina and BigSur only allow 64bit apps to run.  I am on BigSur now and have Autostakkert3 and Registax working using wine. Unfortunately PIPP has some libraries that are 32bit and won't work.  I don't think it is actively supported any more.

Awful news.

I got mine from ALLNET China.  Couldn't find a uk supplier.  It arrived in 6 days.  

The Rockpi4b is supposed to have the wifi connector on it but the one I got does not!  The internal wifi works reasonably well even in the ECOPi aluminium case.    (UPDATE) Just discovered that they do offer a UFL antenna connector for $0.60. as an option and will even fit it for you.  Wish I had known that before.

One thing worth mentioning is that it does get warm.  The rk3399 chip certainly needs a heatsink, the case I got has a built in large heatsink and came with thermal paste to ensure you get a good connection.

I have now got vnc working using tightvncserver on the rockpi and open vnc on my Mac.

I am impressed with how this little thing runs.

I decided to use TwisterOS which is Armbian based on Ubuntu.

I added the repository as suggested and it worked like a dream.

Now running Kstars 3.5.3 stable.

The Rockpi4B with the Western Digital NVME Black M.2 memory simply flies. Its way  faster than the my RPi4 with an external SSD.

Now I just got to figure out how to get vnc working and I will be very happy.
