Hi everyone Trying to set the black level was difficult. Can't find black anywhere in this. Is there any? 2 hours no filter. 30 mins UHC. Thanks for looking and clear skies to all. 700d on 208 f3.9 : ISO800

C'mon guys. New moon. Here's our current EKOS TeamViewer from brightest Benidorm. The ridiculous and the sublime! Cheers.

That's good. You could try wavelet denoise: GIMP. Cheers

plus maybe also 4 second snaps with the telescope pointed somewhere in say, Cygnus? Start with the focuser all the way in and then at about 5mm intervals racking out. You should begin to see stars at one of those focus positions. Unless you have a bright star in the field of view, it's unlikely you'll see anything either through the viewfinder or if you have a dslr, via live view. Which SLR are you using? Is it a film camera? Cheers

Hi Great image. I don't think it's a limitation. Maybe it just needs denoising? There's not a lot to work with on the .jpg but with the .tif, you should be able to flatten the background completely. I had a go... Cheers and HTH.

Be sure to reset the mount model after the flip: HTH

We'll gladly look after it for you. I mean, you wouldn't want it to fall off 😉 ... But seriously, I reckon it'd do the same shot in less than half the time. It would make an interesting experiment. Cheers

Hi Is the -computer/software- time set correctly and in sync? Cheers and good luck. It's usually something really simple.

Hi Wide field? If the Rokinon is up to it, the 5d will get you horizon to horizon in 2 frames with plenty left over for stitching:) HTH

Hi everyone We had the fast reflector last night, so had a go at something faint. It's the bit in the middle of the veil nebulae that no one usually bothers with. Instead of taking fewer long frames, we took loadsa short frames. It's less noisy that way and you seem to get more stars, but it needed 8 threads with the .fits on a SSD to process before it went dark again;) A bit disappointed with the blue-green. We sometimes add some UHC frames to this sort of stuff which helps. If anyone is visiting with an O filter, do pass by:) Poor processing anyway. 700d on pn208 @ ISO800

Hi. Get SharpCap and use it to focus the guide camera on the horizon during daylight. Unless you're -very- close to focus, PHD2 frames will show only what you describe. HTH

One day in the far distant future maybe we'll be good enough and anyway, we only have old dslrs:( Thanks for the comment though.

Hi everyone We got back in the early hours having erm, teamviewered progress in between rounds carefully at all times. EKOS was still hard at it, so we left it be... Had I been present, I would have tweaked something unnecessarily and ruined it. So the moral of the story is; set it going and get as far away as possible! First time we got a complete bubble, albeit orangish. Let us know what you think, especially on star and bubble colours. Cheers and thanks for looking. 7635 + m52: 700d @ ISO800

Clear but hot here in Alicante with EKOS hard at work 12 frames into the bubble and m52...

Perfect:)

I think that compared with an astronomical telescope, the lens would be flipped vertically, but judging by the angles an eq mount gets into over an hour or so, I think the angle humans interpret it as is constantly changing. Also, compared to our reflector image, it's flipped horizontally. And what about after a meridian flip? Ahhgghh! I'm giving up.

Hi everyone We converted our wide field setup from flimsy narrow dovetails to wide versions and added a steel bracket for right angles. The built-like-a-tank Tair-3s now holds at all angles;) This was an attempt to capture the dark nebula which extends west from the cocoon. Not sure If I've the correct orientation though. Do we have orientation for astrophotos I wonder? It has a nice flat FOV. I think it was designed for medium format; there's no vignetting. We tried to match the colour with that of the same target we took with a reflector but couldn't get it as FWOABW dreamy. Anyway, thanks for looking and clear skies. ic5146 and b168 in cygnus eos450d @ ISO400

Saludos desde Alicante:)

I'd try modifying your dslr first. It will cost you under €100 and you get colour thrown in. To get colour images in monochrome of anything like the same size is gonna cost you at least €3000. I witness monochrome imagers frequently. By the time they've found out why the filter wheel isn't spinning, we've got 20 frames from our cheepo 450d. I'd say that if you had decent skies and an observatory, try monochrome. Otherwise go with what you already have. I've a modified dslr. My next move would be an asi294. I'll see myself out!

Hi everyone There's dust everywhere you look so not sure I've got the black right on this; I don't think there can be any black. Again, google images throws up all colours for the nebula bit although there seems a slight bias toward pink, so that's what we have. Do let us know what you think if you get a moment. Especially the black and the colour... Cheers and thanks for looking. 700d; 2-1/2 hours @ ISO800

Hi again Not sure I gave useful advice. Did you get any images in the end? Cheers

Hi everyone Two views looking south. Almost linear sensible and couldn't-resist-pushing-it stretched versions. Thanks for looking. Any preference? takumar 55mm, eos450d: 90 minutes @ ISO400

Reims. Handy for the Veuve Cliquot afterwards. We hired a Ford XRi in Madrid and drove non stop. The cloud cleared with about 1/2 hour to go. I took a Nikon FM2 with Fuji Velvia on one of those 500mm preset f8 lenses with a teleconverter. Still got a Cibachrome...

... with the added advantage that if when you forget to tighten the saddle, the protruding bolt heads will prevent the whole assembly falling to the ground as you slew the mount EDIT: or, if you'd rather slide it in anyway, just keep the existing screws; you'll need to counter-drill using a 9mm bit to match the short one which came with the telescope.

Hi. How about a lens designed to cover full frame? It may work out more economical and you also have the advantage of an already flat field. HTH
