Sirius B in my Vixen SD115S. Never had a hint of it in my 8" newt nor C8. Never tried with an aperture mask though.

Or if anyone can suggest a mini pier or extension tube with photo 3/8" and height of around 38-40 cm.

Hi All I have a ZWO TC40 Tripod with Sky-Watcher AZ mount Extension Tube, on top of which sits a Giro II Mini mount with TS80APOF6 telescope and counter weight, say <6Kg in all. Its a bit too close to the ground for me. Does anyone know if its OK to double-stack the Extension Tubes - or will I get too much vibration? Has anyone done this with similar weight equipment? I'll use it for my visual grab and go at powers up to 160x. I tried using it sitting on a low naughty step, which was OK getting my eye to the eyepiece, but then had trouble getting up again ☹️

Siril will, I believe, also process .SER files. Although I had some trouble with debayer with it.

Yes, I think I’m around then.

You've definitely got the hang of this now. Excellent images. Wish I could get to try some images. It’s clear outside now, but very windy.

Thanks @jonbosley, nice picture. They're on my lunar list and looks like I have a wider observation window than I thought.

Do you know exactly when this observation was made?

Fantastic! Looks like you got them to me.

You' may well be right: my rig is just over 11kg on a Vixen GPD2 (rated for 10kg). Focusing and setting the ADC is a wobbly challenge. It's alright for visual but ..... 🤔 I think it's time to sell some scopes to fund an upgrade.

Another attempt at Jupiter, this time using the barlow tube rather than attaching it directly to end of the ADC. This should have given me closer to F28 compared to F21 - better for my 5.6 micron pixel size? Processed in astrosurface (alignment, selection and wavelets), with registax for colour balance and Gimp for adding the text and curves/levels. I think its better than my 24/11/2023 attempt - no grid pattern, and the seeing wasn't as good this time either.

I think (hope) that a Christmas Elf will be preparing my one for despatch shortly. Has anyone tried two of these BVed yet?

Try the BAA exoplanet section pages for loads of info and tutorials. Exoclock project may well want your results posted to them too. 🙂

The grid pattern seems to have come from using 1.5 drizzle in AS!3. But I can't get the image any better, as I don't think I had the ADC aligned properly. I had a further three AVIs from the night, which I ran through WINJUPOS image de-rotation, but the end result was even worse. I need to get some better data. Thanks for the help.

I used raw8 and debayered in AS3.
