@Stuart1971 don't think you get the same adapter on the colour version.

Are you using the very latest WBPP? If so you may be doing far more in the script than you were doing manually, Local Normalisation for example and possibly other stuff depending on the quality setting you "may" have chosen. Just a thought......

ah ok, was just downloading to have a play 🙂

What maths are you using and which images?

There have been some issues with some hosting servers so Stefan put a link up on the discord server. This "might" work: https://discord.com/channels/436650817295089664/513722925677805578/996782019562442823

I had a UV-IR and an L-eXtreme on my old 294MC and these filters are chalk and cheese. If you're trying to pick up some of the emission Ha and Oiii stuff the UV-IR filter doesn't compare at all. As mentioned for reflection targets then the UV-IR is fine but you just cannot compare these filters in any way really I'd say.

Thanks, they're the 3nm versions, I haven't done anything to the image other than combine them and apply an ABE. As it happen I realised I'd combined as a simple HOO actually but this one below is combined in a slightly more complex manner and I tweaked the background a bit. I just needed to see if I could calibrate the 294m as you know what they're like with flats and mine has some wicked reflections, so much so that I had to put the filters in the "wrong" way round as it were.

Finally got my QHY294m set up so testing it for the first time along with Antlia SHO filters. Wanting to make sure the calibration files work etc so thought I'd try a familiar target and see how I got on. This is 15 x 300s per filter and just an ABE on the final combined image as I say just to see if I can get the calibration working more than anything else.......

Fingers crossed....

I would have to check but I am pretty sure adjusting the flattener adjusts the optics. As long as it's at 1.4mm you should be fine however you achieve the rest as you say.

15mm spacer according to the WO page so if you only added 10mm and wound the adapter out a further 5mm to compensate then you have messed things up as you've changed the "focus" of the flattener. What I'm saying is 7A at 1.4mm plus 45mm extension does not equal 7A at 6.4mm plus 30+10mm extension.

ok but I'm still not sure we're on the same page, we might be but I'm not sure. I know the 7A is adjustable, I have the 6A version and it's adjustable to take account of different scopes and as you say to (very) fine tune but it needs to be in the ball park of its design for the scope. For your setup it needs to be set to 1.4mm just like in my setup it needs to be 7.2mm. Is yours set at 1.4mm because if it's not then I am assuming that's why you're having issues. Of course I understand if you need it to be 1.3 or 1.4 or 1.5 etc etc to allow for the vagaries of measuring and engineering and so on but it should not be set at 5 or 10 if you see what I mean as it's then way out of the design parameters for that scope. Once you've done that using the expensive or cheap adapter you then have the 71.4mm of backfocus from the end of the 7A to the sensor to find.

Am I understanding that you're also adjusting the FLAT 7A to try and gain focus? If so you can't do that, you have to set it to what it should be for the scope in question (in this case 1.4mm with additional adapter) and leave it. The back focus is then from the back of the Flat 7A using whatever adapters necessary. If that's what you're doing then ignore me 🙂

Has it gone back for repair again?

Fixed that for you 🤣🤣🤣

These should fit the normal focus side and when fitted the focus is locked solid and cannot be moved manually so there should be no need to be able to adjust focus tension anyway. That's on a refractor but I assume the principle is the same regardless.

And have a message on it saying "Please don't light up my garden" and nobody will be in any doubt as to what you're up to either... Win win

I did say it "could" and "need" to be fair.... You could have created a mosaic 🙂 Not my fault you "wanted" a new camera 🙂 🙂

Yes Britney lol

Still here Sinbad? 🙂

That's the Unity software which has ASCOM drivers already for the Powerbox devices that I am using in NINA for the Switch and Weather elements but as yet no safety monitors. Obv I'm only commenting on the ASCOM stuff I've seen, the Meteo may open up more hopefully... Happy to test one 🙂

Well IMHO amp glow is a non starter as it calibrates out BUT the 294 can be tricky to calibrate in general hence why I didn't mention it. I had one and and had a few troubles, most of my own making, and would have one again but for an easy life the newer 533 has to be the easy, fuss-free option that's the main reason I suggested it. But, if you want a bigger sensor and have no problem dealing with it then I'd have no qualms with a 294 either.

I know you said you don't want to "spend more while you get into it" but that suggests, well we all know what it suggests so my 2p is that if it's remotely possible I'd save your money until you have enough for a 533MC. For all intents and purposes it could be all the camera anyone ever needs 🙂

Yes but not plugged into the USB port in the mount? What is the configuration in the asiair? Going wildly OT for this forum now but genuinely interested so we can move to "Mounts" if you wish 🙂 ........ Edit Oh - EQDIR I guess......

Either way you seem to be getting very good guiding figures. Looking at the cables are you not pulse guiding either????
