Are those shots of the planets just single exposures ?

If so they really are very good for single shots with a dobsonian. 
To quote from the tutorial below "A single exposure of a planet will, unless you’re lucky, record slightly blurred detail, smeared out by the atmosphere. One way around this is to record a video of the planet.
This way you’ll capture lots of poor-quality images, but there should be a few good frames among them. Using specialist software, you can extract these frames and combine them to make a sharp image.
Devices that can do this range from webcams, the latest DSLRs, which can now take video, through to purpose-built planetary cameras with high frame rates, specifically designed for this task."

I have not really done any planetary stuff and concentrate on DSO's so can;t really give much in the way of advice. From my understanding most planetary stuff is done with videos rather than single frames.
THIS TUTORIAL may explain better than I can.

Thanks for the reply and yes he just took single shots, he was experimenting with different settings and he actually has a few more which he’s enhanced on his computer, I’ll share those very soon, thanks again

well done on the images you have already captured.

The moon is bright so a single shot is often good enough.

With Jupiter and Saturn , it is common to actually record video then use a program to extract the best (sharpest) frames from the video then combine them together to produce a far clearer image than any single shot could produce.

This combining is called image stacking.

There are several programmes , many free good ones, who can do this for you.

uTube has a good selection of how to guides and recommendations to help you to get familiar with this.

 

 

For the faint Deep Space Objects (DSO) you will need to capture a number of long single frames (typically from 30 sec to 240 sec at ISO 800 for DSLR) but this requires a tracking mount , but I note you have a Dobsonian (non tracking).

 

some of he brighter DSO , Orion Nebula , M31 Andromeda , Pleiades etc , can be recorded with shorter exposures  (eg 10 sec at ISO 1600) and once again all these short frames (which will not show much on their own) once stacked and "stretched" will reveal some nice results. Not tracking will usually be fine for such short exposures

DeepSkyStacker (DSS) free and easy to use , will do all the combining for you , then use a free manipulation programme like GIMP (a free programme like photoshop) to get the best from the result.

Again uTube has guides

this one is good.

 

 

Thank you so much for that advice 🙏

Hey guys,

I captured my first images of a deep sky object last night after failing several times previously to locate targets.

I would love some feed back on the image from experienced Astrophotographers so I can continue to learn and progress. I did not manage to capture much data, I spent about 45 minutes taking 80 second exposures at ISO 1600 ..I chose 80 seconds to be on the safe side, assuming my manual polar alignment and being unguided would start to have an impact.  The 1600 ISO seemed a little too steep, I much preferred the results with 3 minute exposures at 800. Unfortunately less than halfway through my 3 minute 800 ISO imaging the sun started to rise and ruined the session -.- 

Important lessons were learned and it was a lot of fun, even with only managing ~18 minutes of useable data!

Here is the Andromeda Galaxy, x6 3 minute exposures at ISO 800 with x2 Dark frames at same settings (Camera battery died during), taken with an Astro modified Canon 600D, Sky guider pro and WO Zenithstar 73 + field flattener . Minimal processing done in GIMP.

I have a flattener but notice the stars around the edge seem a bit off...But I think this is most likely due to my polar alignment. 

Any feedback welcome, cheers guys

I’d be over the moon with that picture! So to speak, hope me and my Son can take some similar ones 👍

Just as a post script the telescope is the dobsonian mounted one

The camera is a canon EOS 400 D
