If you are forced into the sale let me know

Thanks Olly It was just the shadow of the spider vanes in the donuts that made me wonder, im used to refractor flats which dont have this kind of thing

Thanks Onikkinen I just wasn't sure with them having diffraction spikes ok a kind.

This might show it more

Hi Onikkinen Yeah its stretched, I suspect that collimation is out possibly causing the off centre vignetting also there is an issue with tilt in the coma corrector which is visible in top right most of all, not sure if this causes and issue with flats though. The donut although its difficult to tell is more like a nuclear sign i dont think this picture pics it up ill try to exaggerate it

Hi Can anybody tell me what causes these shadows im my flats, the look like loads of shadows of the secondary These were taken with a tshirt over the scope which is a 250pds shooting at a light panel

Just to confirm there is no grub screw to remove the single speed knob

Hi Stevie, Its more than possible I missed the grub screw, its installed in my dome so not the best light in there. The coupler I modded fits nicely the issue is normally the bracket is fixed with the locking screw which is normally in the centre of the focuser plate. on this one it isnt its got 2 both off centre. I could drill out the bracket I have but it would be very close to the edge.

Im probably wrong but I don't think the single speed side was removable. Unfortunately there isn't a ready made bracket at FLO but they are looking if the MN190 bracket will fit. If not I'll probably adapt the one I have. I've drilled out the coupler to fit already but it needs to have the bracket secured properly.

Hi I have swapped it over now. I wanted it on the inside because it overhung the front of the scope and also it was just neater for the cables.

Thanks Both, it is set up left handed so you would of been ok on this one.

Hi All I have just come into possession of a Skywatcher 250pds but need to add a Lakeside motor focuser to it. First problem is the dual speed knob is on the wrong side, it is towards the front on the scope, does anyone know if its reversible? Also there isnt a bracket mentioned on FLO's website, does anyone know if one exists or at £50 for a bent piece of aluminium would i be best to fabricate my own.

Great Alan, nice to see a rarer object

Give the device hub a go it seemed to work fine when I was messing last night.

exactly what i have done and all seems to be working fine. got to do proper tests though and that will be after i fix my dome issue. Tomato have you tried it through Device Hub? also what version of Ascom are you on

Hi Does anyone know how to enter a negative GEM value in Device Hub, i need it to be -46ish. Also not sure if somebody could confirm but in POTH my radius was set to .9935m so assume it is just going to be 994mm

hi tomata i have managed it now through device hub, but just got the next problem of trying to configure the dome settings in it. I cant work out how to put a negative gem offset value in

Hi tomato, i also have this problem but cant get my to work with your work around either

Starnet, remove the stars then add them back in in PS layer set to screen. I've being experimenting with it so stars don't get white clipped.

Hi Ive been messing with this one for quite a while but ultimatley had terrible RGB data especially in green, i think at the time of shooting the green had either been affect by high cloud or even sunrise, this was shot back at the start of September. This is taken with ASI1600mm with Samyang 135mm Ha - 29 x 300sec R - 30 x 120sec G - 12 x 120sec B - 30 x 120sec

Nice pic Bob

Cheers Stu, I thought the view would be to wide to get a planetary nebula

Hi This is my attempt at Kembles cascade, if you stare it is there. Did try to selectivley enhance the stars In the cascade but still kept bringing out too much background. Image details AS1600M RGB 120s subs 2hours each channel with samyang 135mm Also there is a strange blue object top centre anyone know what it is, Artifact, star gone strange?

Yeah thats the one cheers

Hi mAnKiNd Where did you get the bracket for the Stepper motor?
