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.
I've been dabbling for about a year and am having a lot of fun.
Nothing too serious and I don't have mega expectations but I'm starting to wonder if my images could be sharper and there's something I'm missing.
I'm attaching a picture which is the best 10% of a 3 minute video with 500d 'bolted' straight to the 200p f5 scope. No filters...no barlows...just camera straight on.
It's sharpened and saturated after the fact so in every way this is the sharpest I can get it.
I've always had the same issue whether it's with a single shot, stacks of shots, or stacked video.
Views through the eyepieces (circle-T 12.5/25) are mega sharp!
I'm happy that collimation is very good and it was a remarkably clear night tonight.
All in all I'd be pretty happy with this image (maybe over exposed a bit...) if the craters with shadows didn't make me want to rub my eyes.
Thanks in advance for any thoughts or advice!
Had a great view of Mars last night at ~11.30pm. Best I've seen it so far this year I think. Sketch below.
I think the darker regions in the S are Mare Cimmerium, Mare Sirenum and Mare Chromium.
Could also clearly see the South Polar Cap and limb cloud at the following side of the planet.
