Messier 33 - 9th october 2020

Skywatcher quattro 250s and Atik 383l+ with the efw2 and 7 pce filter wheel with 36mm unmounted Baader filters all on the skywatcher azeq6.

L-120 SEC TIMES 5 = 10 MINUTES
R-120 SEC TIMES 5 = 10 MINUTES
G-120 SEC TIMES 5 = 10 MINUTES
B-120 SEC TIMES 5 = 10 MINUTES

no darks or flats

i did boost the colour a bit 

40 minutes in all and its a bit noisy but all in all not to bad especially for Darlington uk
 

they fitted a shade to the new led street light next to my obsy strait away but it was useless so i made my own with a small aluminium frame sandwiched in between 2 flooring mats and bolted it to the lamppost and used a long pole to push it up and it works great now.as seen above and behind the home made dome.

Great images Chris.I would imagine difficult condtions under the Darlington skies.

Mick.

oh just a bit mick and thanks ,the worst is the blue gradient from led street lights but i found a way to deal with it to some degree

oops i forgot to balance the background oh well so much to remember hope this looks better ha ha.

Well hopefully you can reveal all when you're done testing/experimentation! 

thanks Tom and all will be revealed when im finished even if it fails

Just now, Tommohawk said:

I'm intrigued! Is this a "hard" filter ie a real glass type thing you use when shooting, or a virtual one used in processing?

it is a real filter that screws in front of the lens 

1 minute ago, Tommohawk said:

I'm sure you're right... but not clear what you mean by night flats? 

night flats is something i am experimenting with - i have made an opaque filter to take care of the noise and uneven sky glow at the same time but its to early to confirm that it works in most situations but it looks promising.

I'm looking at the star adventurer now for my canon 450d along with my tamron 70-300mm lens, to see if possible I x as n use it on my tripod from dark sites, how do you rate the star adventurer 

i rate it very highly so long as you get the balance right and the polar alighnment sorted

thanks Tom

yes i was surprised about the noise level the 90D seems to handle it well but i think what helped the most is the night flats. 

thank you Lee

Andromeda

120 - 30 second exposures at iso 6400 and at F8
canon eos 90D (not moded) with 70-300 f4/5.6L at 300mm on the Star adventurer.
used bias frames and a night flat filter developed by me needs more testing
no darks no noise reduction no colour enhancement just levels to line up the colour peeks and increased levels at 10 points per itteration as shown by steve chambers on his processing video in stargazine on SGL. and cropped get rid if stacking artifacts.

stacked in dss and lightly processed in photoshop cs5.

all comments and critique welcome thanks

lovely image Peter

I don't know what stopped it from working but it was well on its way to taking an infinitely long exposure - the only thing that stopped that happening was the cloud that came in after a couple of hours!!! Examining the CCD Commander logged revealed that the close-down sequence had halted two steps from the end as the camera was still trying to warm up to its first warm-up point of -10 degrees so it looks like the connection to the camera was lost. Reconnecting the camera remotely worked perfectly so I guess there was just a minor 'glitch in the Matrix' 😎 To be sure, I spent an enjoyable 10 minutes in the dome today disconnecting and then reconnecting every USB and power cable in there as potential preventative maintenance.

its not an atik 383l+ mono is it i have found that any kind of power fluctuations to my 383l+ tends to make it do very strange things so now it has its very own psu and it seems to behave now.

The colour version is underway, Chris although I had a camera fault last night which lost me a couple of hours of subs!

ouch i hope its all ok now Steve never heard of that filter problem before ,but plenty of others like filter wheel no connecting - camera window freezing up - scope not seeing anything but that's just my stupidity without me the gear is fine lol.

the OIII looks like its enveloping the whole object even in the mono version cant wait to see it in colour if thats what the mono looks like

it looks like you have loads of OIII in that image  its very nice indeed

the only suggestion i can give you with the stuff you have is to make sure your hinge on the barn door tracker is pointing at polaris so you will be able to track for longer and no more the 10 seconds at 18mm or you will start to get star trails allso you will be able to use the 1100d at iso 3200 without to much noise and dont forget to take darks - flats - and bias frames to calibrate the noise and vigneting -this will help http://deepskystacker.free.fr/english/index.html there are help videos there as well as the free software.

thank you mark

clear night for a change on wednesday so i got out the old SA with the new cam and lens and i am very pleased the way they worked.

stunning capture and processing Tom

great image well done

yes it is called color efex pro and in that select detail extractor and use the sliders to increase or decrease but not to much in the detail or contrast as it will show more noise you just have to play with it till your happy but there is so much more in these tools just go gentle with the adjustments hope this helps

Glad to see there's other old farts rocking older PS versions! I'm still holding on to my trusty CS3!  From my experience a lot of the plugins out there nowdays don't work with CS2/CS3 as theres a lot of functions that just arent present in older versions.

 

That said, it's still possible to reach the same result, it just takes longer and you have to do it "manually" using the tools available. 

yes but when you get your flow down you can create your own actions then that will speed up  the process and make it all a bit faster but faster is not all ways better

Thanks Toxic, I'll have a look at that - I hope these plugins work in Photoshop CS2 as I don't have a later version - do you know if they do?

yes they do that's the version i  used to have but now on cs6 but there is not much difference tbh
