I'm a noob but have the sw gti tripod and pier/extension since February. Using the pier instead of extending the legs of the tripod keeps it low whilst making sure my dslr doesn't hit the tripod legs. It also looks pro I'd highly advise searching YouTube for every sw GTi video. I'd also suggest doing same for how to polar align, especially if you've never done it before. If only to understand the basics of it. Also Nina control software is incredibly amazing even for a total noob as I was and still am. I haven't looked through the polar alignment scope since about march

Previous owner made a hole for a pier in the decking. Also, Napalm is your friend.

This I need to try on my image for myself I think. I think gimp has the ability to do each of those processes so I can compare the results. I really appreciate your effort. I've seen a lot of your other forum posts and they are incredibly helpful.

It's a strange coincidence one of my favourite YouTubers, sky story, just released a video on (not watched it all yet and, as usual it's rather above my pay grade) Gaussian blurring the entirety of the starless mask and selectively removing parts of that blur. To remove mud and noise. Yup, mud. He should probably just wipe his shoes more when returning inside.

Can't hurt to try. I really don't like the idea of reducing resolution, as I associate that with losing detail. But I assume with plate scale (?) and such stuff it really doesn't. I should be thankful we live in a era when I can just sacrifice a little time and effort to experiment and practice this stuff. No film and processing costs involved

Binning is something I've really not looked at, as it seems to me to just be reducing resolution. So many do bin though, there must be good reason. I'll try and have a play with it when I re process this image, thank you. I'm hoping the tilt is down to me tightening the focus tube lock screw thing too much. Maybe.

I believe you but I'll have to research this. I've not done any blending and I think reason I avoided median filter is I didn't like it's results. I put this down to not understanding it.

i think you put this very very well those images show it pretty clearly and i only find the first one acceptable. my image shows some of the third and fouth images i think, so going forwards ill try and minimise getting those effects. not sure how yet but i hope ill learn. i've not really used the median filter in siril yet, so i guess ill start there. im going to post process this image again from a point right after stacking. i'll probably end up with an almost completely different result as for adding more hours to this, im not sure. the composition isn't great, plus i want to crop out about the left hand third because the star shapes are not nice. also, after this result i think i can take some decent images of other Ha targets in the same sort of area of the sky, heart nebula, elephant's trunk etc.

Are you talking about the blobbyness or paint stipple effect? Because that's what I was afraid of. I'm messing with some filters in gimp which reduces it a bit, I think.

That's really nice. Can clearly see the teeth and jaw of the alien queens skull:) Is your 6d stock? 6d is full frame?

Ty so much I feared this hobby could be a little humourless and very serious but with the weather here, I think humour is essential:( Camera is #1 priority. Imx585 was top of my list but could be a long way off.

Yeah but often the buttons on the bottom row (apart from stop ) are unresponsive to mouse clicks. Next chance I get ill run through it again and if my results are decent won't touch them again. Except exposure time. That seems like it needs to be tweaked from 1 to 2 seconds when changing target. Cheers for the help.

congrats

yeah im not quite up to that in gimp yet. but ill get there eventually. at the moment i just want to put lens flare on everything.

no data should be clipped in the above. siril has a handy display of how much is going to be cliped in its ghs/istrograms and im usually very careful to not do that. i photometric colour calibrate after i send it through graxpert (tiny crop, gradient and noise) after stacking. my thinking at the moment with a stock dslr is to try and just show what's there. i have a t least one dust spot my flats couldn't handle and i could paint/clone it out, but i don't think that sort of thing helps experienced people like yourselves constructively criticise and help i still think sensor is a tad too close to the flattener and there is some tilt (?) on the left hand side. im hoping i can reduce that a bit next session by not using the focus lock screw thing quite so tightly.

i think i need to have a lie down

im actually borderline smug atm. i've been avoiding this area of the sky, elephants trunk nebula, ngc7000, pelican nebula as i assumed i'd get nothing from a stock dslr (and i've looked at a lot of people's stock dslr images on astrobin etc) but it seems (shockingly) i was completely wrong

very kind of you to say. the mount isn't the az version its the eq mount version and i agree with you, im really happy with this, bordering on amazed with myself. hence why im double checking i haven't just over stretch it. tbh i think it could be stretched a little more which im playing with atm, but don't want to over do it

stock canon 600d and my "non premium " crap gear is in my signature. I think this is the first 'proper' image ive managed and less than two hours it does have a bit of an impressionist painting look to it, which i rather like, but im not sure if that's 'good' or not i think i can improve it a bit more, i haven't bothered putting it through basic stuff in gimp yet its ngc7000 and some of the pelican nebula. couldn't get them both in same frame without rotating my ota in its rings which im trying to avoid.

im a bit surprised with this result as i really quite like it. but is it as nice as i think it is, or have i just over processed noise? 43 x 120sec subs, crap gear

very very nice image. even more so for 2 hours tit

i think this must be my best image so far. almost 90 minutes of 120sec subs. or am i just over stretching noise?

Not even noticed a hw accelerator on/on switch, but I did notice a improvement in detail of the gradient corrected and denoised outputs in 3.0.2 over 3.0.0. This is an amazing piece of free software.

So I got 22 x 2min usable subs on m57. It's a tricky b#£&@#£d to process, and I might be flogging a dead horse. Fortunately it seems I have undiscovered sadomasochistic tendencies, so flog away I will. In my head and from others' images I've looked at, its green with a red ring around it's edge and a star(s) in the middle. Removing green noise in siril turns it blue but I can see the red ring, though maybe that's ca. Who knows? I will flog it some more. of course, I mistook m57 for M27 dumbbell which I should have imaged cos it's bigger don't tell anyone. my 3 usable 2 min subs on m31 as sun rose are not apod quality who knew? But m32 was definitely still there and heading right at us. Hopefully I have 30 x 2 mins on NGC 7000 the alien queen skull (as it is now known except for some colonial rebels ) but been to scared to post process it yet but did see the jaws/teeth in a quick auto stretch preview. For a non premium telescope and stock dslr no filters and with no astro darkness I'm quite chuffed. Again. also 0.8" RMS auto guiding with my non premium mount ......mostly. Would like to say thank you all, again, for so much help from so many people on this forum. It would be a huge struggle without it.

I need to get some Herbs de Provence chipolatas now ty i somehow thing my local Morrisons won't sell them
