Imaging issue with dobsonian telescope


Recommended Posts

Hello there,

I'm trying to reignite my interest in astronomy after a few years off.  I want to get into imaging (not in an expensive way) beginning with a simple setup.  A few nights ago I was in my back garden with my Sky-Watcher Heritage-76 Mini Dobsonian and Canon EOS M camera connected to an eyepiece adapter (this one.. https://www.amazon.co.uk/Celestron-93640-Universal-Barlow-T-Adaptor/dp/B00009X3UV/ref=asc_df_B00009X3UV/?tag=googshopuk-21&linkCode=df0&hvadid=309904628344&hvpos=&hvnetw=g&hvrand=9227521492625195769&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=9045736&hvtargid=pla-403917112227&psc=1&th=1&psc=1).  I pointed my scope at the setting half moon and all I could see was a huge orange blob with a black circle in the middle, obviously this has something to do with focusing so what do I need to get this to work as my setup is already nearly bottom-heavy?

Either that or it might be a lot easier to use my Pixel 5 phone connected to the eyepiece, can anyone recommend a good adapter for this please?  I've seen this on Amazon.. https://www.amazon.co.uk/Svbony-Universal-Cellphone-Binocular-Monocular-Black/dp/B016EILBAY/ref=sr_1_10?crid=2D2EEIA81TKYX&dchild=1&keywords=mobile+phone+telescope+adapter&qid=1606225704&sprefix=mobile+phone+tele%2Celectronics%2C175&sr=8-10, but folks say they've had mixed results.

Thanks very much.

Rick.

This is a much better smartphone holder. I have used it and it works well. Did try one of those you linked to but got rid of it as the clamping mechanism wasn’t that good.

Few shots taken with this phone holder.

This is a better although more expensive holder.
