Hi Gary,when you fit your new belts put a drop of threadlock on each bolt,no more worries! Regards Mike -
I have mine sat on top of the finderscope. I started a thread on here about the mods i have done to my dob. I will see if i can find the link as it shows a picture of where my rigel sits. Found the link -
Hi Rusted, I'm afraid I cleaned up my hard drive recently to create space, so the original image files of that particular one are somewhere on my external backup (all I have on my laptop of that image now is the jpg). I'm not too sure how to extract only some files from a Time Machine as opposed to restoring the whole thing, and I don't really want to rewind my whole laptop back & lose all the cleaning up I did! However, there was another batch of images I took that morning which I have not yet gotten around to doing anything with. It's of pretty much the same quadrant of the sun, and when I randomly opened one image in LR and ramped up some balance levels, the same prominence does appear. So I can offer up those originals in the dropbox linked below, in case that would be helpful? Its only about 30 PNG files (vs the about 70 I think there were for the image earlier in this thread). I've also included two sub-folders in that dropbox with some darks & biases I took that morning - unfortunately I didn't take any flats b/c I wasn't sure how to do that for an Ha scope 🤔 Cheers! https://www.dropbox.com/sh/s5s0ibkhmdqfbnd/AAA6CP4--E6_BG0hMm7XxUAma?dl=0 -

Hi Mike any chance of posting the link to one of your posts where you showed some sketches you did? I can't seem to find it, I want to show my wife what you can see with a 100mm Tak.· 3 replies
I think you were commenting on someone buying an Altair Astro refractor.
Thank you,
Martin.

Wind and rain! Rain and wind!· 0 replies
So rather than "pining for the fjords", I thought to try a bit of astro 'DIY' light. Managed to fit an old Orion EZ red dot finder onto my Altair astro 66mm Lightwave refractor.
Also decided to reuse my redundant QHY5v planetary camera for obtaining low res spectra. Managed to complete a few basic calculations and mount a transmission grating at an appropriate distance from the imaging chip. Then set about getting my laptop to communicate with the old camera. Went to QHY site and downloaded the most recent driver for the QHY5v.
Downloaded a more recent version of Sharpcap which seems to work with the QHY5v using ASCOM. Need to work on settings as first captures were hyper noisy. Not really sure what I am doing but I've never let this stop me in the past. "Ever backwards and downwards"!
George now tucked up and pleasantly cosy in my sleeping chariot.

I saw your question on the ASA site about sky flats and Sequence. If you are still interested, I have managed to get this to work quite well on my installation at E-Eye. After setting up the filter sequence configuration file, you just click on "Dusk Flats" and then select the configuration file from the window which pops up. Do not press START NOW or START@TIME. As soon as the sun reaches 0 degrees, the mount will slew and start to make flats. Therefore, you do need to make sure that the roof/dome is open! In this mode, Sequence does not open the roof/dome automatically. (It would help if they told you that in the Manual.....)· 0 replies
The trick is to get the configuration file set up correctly. I have mine set to make dusk flats with the following filter sequence: SII, Ha, OIII, R, G, B, Lum. I make 5 exposures with each filter. That seems to work well in relation to the speed at which the sun sets.
Of course, if you want to make dawn flats, you need to reverse the filter sequence.
Hope that helps!
