SW 80ed 600mm fl

A modified Canon 600D, ZWO ASI 120 colour guide cam and Atair 60mm guide scope

Ok, so far in regards to the data I have been tryng to stack, I played around with DSS and results so far - Dark's added from another night - didnt work!. What has worked is going into - Register settings -parameters - cosmetic and ticking 'Detect and clean remaining Hot pixels' I set this to 1px as 2px did something to the stars! 1px seemed to reduce the amount of stars in the final stack but i didn't noticed any other issues with the tiff so I'm guessing its ok to do this?

Thanks for that, i will give it a try! 👍

Il check what its set to, cheers 👍

Apt for camera control, I can't remember the dither settings but I'm pretty sure they are set big enough for what a DSLR needs, I've not had this issue until now though and I've been dithering for a few sessions with out this issue!

Yeah it's worth a try, they won't be at correct temperature though. I'll also have a look at the settings in DSS and have a play around. This hobby really gets you banging your head against the wall, 1step forward and 2 steps back!

The thing is, I did dither! I've been looking into it and found the same result, that it's walking noise, well walking hot pixels actually! So if I'm dithering, what else can cause it and can it be removed from the subs I've already got with a certain setting in DDS!?. I don't take darks now because I dither.

Il look again, if they are then could that be a camera issue? Which I bloody hope not!

All settings are already on Kappa-sigma-clipping. Ive not changed any settings from when the stacking was working before either.

Does anyone know what could be causing the coloured "pixels" in the stacked Tiff from DDS? Camera files are from a Modified Canon 600D. They are not present in the Subs from what I can see. Ive done some stack tests and they are coming through even with just stacking the Lights so no Bia's, dark's or flat's. Ive not changed any settings from before.

The one pictured is the one I got, run it on the full heater setting (don't bother with low or medium) which will feel warm to the hand when on. I've had them on a while now and they appear to be doing their job as I've not had any dew!

They come in just one length from memory, il double check but what ever length it came in, fitted perfectly. I used the same one on the guide scope and just rapped it round over itself, keeps it nice and warm. So far no dew so that says to me they are working 👍

I've got the below dew heater off Amazon with its own controller built in, its been working a treat on my SW80 ED. Just plug the USB end into a phone charger plug then straight into the mains. I actually use two, one on my guide scope as well! 👍

Yeah your 100% right in that I would not sell the other scopes without testing and being happy with the TS 90mm first. For me its about combining the two scopes that I currently have into one, hopefully get better optics, and in saying that I'm not expecting a mind blowing change but a future proof scope for when I move onto either a dedicated mono or OSC (hopefully later this year). I fully appreciate that with my current Camera (Canon 600D modified) not to expect a change in the quality on my images as such. I was hoping those experienced with using the TS optics 90mm for AP to share their experiences, I know there must be some using it out there!

Your definitely right, they certainly have their draw backs in terms of colour. I think there's always a compromise with every aspect of this hobby

It's lots of trial and error in this game, maybe your seeing was just to hard on the target at the time. Keep at it 👍

I'm surprised you didn't get some more details out of the Horsehead Neb even with the conditions. This is one of mine using the L enhance with my 600d in bortel 6 skies

The main thing is that if your happy with the results then it's all good, they are nice images. I just personally can't see any difference for the cost over the L - enhance and I think that's because of our age and type of camera 👍

I've been reading up today of what possible future scopes and cameras that I may move onto for astrophotophotography later this year. In regards to scopes, one of my possibilities is the TS optics photo line 80mm f6 triplet. I currently have the SW80 and 72mm ED DS Pro. With regards to the 80mm, I like the 600mm fl which I can make wider and faster if I won't to, because of that I hardly now use the 72mm. I've contacted a guy today in regards to a TS optics 90mm f6.6 600mm triplet super Apro and would like to know your experienced thoughts on if it would be a good/right move to sell the SW80 and 72mm and have the TS 90mm as my only scope? And look to get a reducer if my current one is not compatible. From what I've read they appear to be pretty good, I already have a reducer which I'm hoping will still be compatible with the TS scope as at this time I wouldn't won't to spend out on lots of other needed parts if I can help it so kind of hoping it will be a pretty straight forwards transition of scopes! Both of my current scopes are great so it needs to be the right move.

Lovely images but I definitely can't see anything extra over what the L enhance has produced with my 600d.

I've had no issues what so ever with focusing with the L-enhance, I've not had to adjust my routine to do so. Its definitely a great little filter, even more so if you can pick one up a little cheaper second hand. I would be interested to see some good examples with the L-extreme and an older Canon but to be honest, with the cost of one and my plans to move onto a dedicated camera later this year, I probably won't be getting one.

He does state that the older Canon's may struggle with this filter which is why I'm hesitant to spend out for it to use with my 600D. I've recently seen it used with an older canon camera on the Rosette Neb and it didn't appear to add anything! It might just be a case of seeing how it goes for you but its an expensive filter to do so if its not certain to make a great difference. The L- enhance however, has made a decent difference to my images combined with my 600D.

Anyone else had an issue with the Skytech CLS clip in filters being loose? Mine arrived today, attempted to "clip" it into my Canon 600D, it's loose and spins around the recess it's supposed to clip into, not a great product then is it.

Cool, seems more than capable then!
