It looks great and has helped drive some thinking for my travel rig obbo. I'll be aiming for a peaked apex roof which rolls off the back. The peak allows the sides to be lower for horizon to horizon scanning and the front to be lower for south viewing while the north remains high, otherwise all the sides need to be higher than the scope flat on the mount. The reason I mentioned the liner was that on my old obbo I didn't bother and use of pitch lap board meant it didn't matter..

anyone know where I can buy a 60-tooth gear that's 1" in diameter?
skybadger replied to orly_andico's topic in DIY Astronomer
Hpc probably or sdsp -
Out of interest, why did you bother with the Tyvek ? Also, did you consider reducing the height of the front wall to get better horizon access, resulting in a sloping roof ?

But the point is that it is discrete and distinct and not an analogue increment. So the the intent is that it is a 'step change' . Seems fair to me.

Solar guiding - first test of PHD2.planetary on AR3685
skybadger replied to Rob63's topic in Imaging - Solar
Thanks. This arose because if got confused with Firecap. I shall give it a try directly. -
Solar guiding - first test of PHD2.planetary on AR3685
skybadger replied to Rob63's topic in Imaging - Solar
Sorry. I am talking rubbish when I say I've been trialling normal phd2 as a solar guider, actually I've been trialling firecap as the solar guider. Don't know where my brain went to there. -
Solar guiding - first test of PHD2.planetary on AR3685
skybadger replied to Rob63's topic in Imaging - Solar
Thanks. So you think the two versions will be combined ? I read with interest the use of the guiding assistant to adjust polar alignment. Is this also possible I the standard version, say using a limb of the sun to identify drift ? -
Solar guiding - first test of PHD2.planetary on AR3685
skybadger replied to Rob63's topic in Imaging - Solar
Are you guiding on a separate imager in this picture . Does this work by guiding on the high Res high scale picture from the main imaging camera ? -
Solar guiding - first test of PHD2.planetary on AR3685
skybadger replied to Rob63's topic in Imaging - Solar
I'm slightly confused I've been trying just this with the existing auto guiding capability of phd2 on the AR3664 and having not great success with the Nyx mounting it's on. It's been able to lock onto the spot fine but still not achieving a fine lock. Also it's not been correcting all the error. Is this because it's just not the right tool for a solar disk ? I will give this a go but would like to understand whether this will be a feature of mainstream phd2 {desired} rather than a stand-alone Cheers -
Three images from early this morning 20-05-2024
skybadger replied to fwm891's topic in Imaging - Deep Sky
That's no guarantee ! If you tandem mount them side by side you can shim them and lock them down and get similar fields. -

I'd be interested in seeing that braced playe. I use one fixed and one on an adm adjustable plate and have spent time getting them bang on only to flip it across the sky and find it tens of arcseconds out. Maybe that's not so bad. I second the Nina dithering master/slave setup. Voyager supports array mode but you trade multi-camera support for multi-target support unless you write some external scripting. -
Nautical Darkness equivalent to a moonlit sky?
skybadger replied to tomato's topic in Imaging - Discussion
My measurements with my Sqm meter show astro dark tapering off about 0330 UT which is 4.30 BST but getting a dark sky after sunset only arrives fully dark at 2230 UT/2330 BST. So 5 ! full hours, where the dark arrives at the predicted astro twilight time and sunrise doesn't impact for a full 2 hours after astro twilight ends so I adjust my imaging periods appropriately. My latitude being 51.5N, hopefully this is representative -
With the right mini pc you get enough ports for the smaller accessories and just leave the heavyweights to have their own power wiring. Especially if the camera is itself a hub. So no excuse for horrible wiring!

Milky Way Tenerife Island

We spent 7 nights at los Parador last year and slept by day while imaging all night every night. -
New Sliding Roof Mini Garden Observatory Build
skybadger replied to Domain105's topic in DIY Observatories
Very nice build. I'm planning to make something similar for my portable rig while at home and it would have to be as small as possible. I'm interested in the details of the drawer slides since they seem to be bigger and stronger than normal drawer slides. also, how do you get out when the roof is open? Must be a bit of a squirm? Would you change that direction of roof opening to towards the house ? How does that end do in the driving rain since there is little overhang compared to the long sides ? Would you extend the length of the roof to compensate ?- 70 replies

Can you ssh into the asiair and look at the filesystem , see if there is an indi catalogue and what the indi catalogue says ?
-
If you are convinced it's XML what's the odds that it is indi ? And that's well documented .. It would be quick to knock up a test.
-
I'm really interested what the actuators are, linear servos ? Also how the stack is clamped once adjusted or is it sufficiently stiff once adjusted it doesn't need clamping ? Finally, this is normally a 'once and done 'operation, what's the argument for making it easy to repeat but expensive and heavy?

Anyone Else Using CcdCiel/CarteDuCiel?
skybadger replied to JonCarleton's topic in Discussions - Software
I use cartes de ciel all the time on windows. Less faff than others. Also does orbital offsets with phd2 to track comets. Also have ccd de ciel for when I want to run three cameras in spectroscopy mode.- 10 replies

That's a nice setup. Clearly need some larger scopes.

what is the best guidecam for OAG's ?
skybadger replied to Northernlight's topic in Discussions - Cameras
I run at 2000mm on a lodestar 8um pixels binned X2 using an oag. Typical exposures 2.5 secs and guiding .5" Sometimes it's hard to find a star but rarely. -
Hi all, Ben trying to use my RC12 for Jupiter imaging but reverted to the refractor. This is my Vixen NA140SSF at f/22 with ASI178 and lrgb filter set. Captured with Firecap, stacked in AS3 and sharpened in Maxim.
