Which 3 of your eyepieces get the most use, and why?
Ian McCallum replied to F15Rules's topic in Discussions - Eyepieces
I used the 28mm 2" SW LET and 8" Dob on the moon, last night. It was breathtakingly sharp in it's clarity!😮 -

Ian McCallum replied to F15Rules's topic in Discussions - Eyepieces
For me it's my second hand 28mm 2" LET, great for wide views. Second would be my BST StarGuider 12mm ED, for closer in observing. Lastly would have to be the BST StarGuider ED 8mm for occasions when the seeing is good. -
These were taken with a smartphone holder attached to the eyepiece. Another wee muck about with the Sky-Watcher Evostar 120 achromatic refractor and the moon, this evening. I was using a Meade Super Plossl 15mm eyepiece. I actually saw Orion for the first time in ages. Betelguese looked not too bad, as was Rigel. I could even make out the Orion Nebula and 3 of the Trapezium stars too. VID_20211120_213135.mp4 VID_20211120_213220.mp4

Firstly, Jupiter with the Sky-Watcher Evostar120 Achro - using the whole BST StarGuider range 25mm-3.2mm. CA was apparent right through-out the who range of magnifications. There was a bit of a breeze this evening, which didn't help seeing. I decided to move onto Almach, which I discovered by accident recently. I used the whole range of the BST eyepieces again, but couldn't obtain a totally clear image, as seeing wasn't great. CA was present on the images I was viewing, having being previously spoilt by a 8" Dobsonian.

Some WD40 or similar to break down the foam adhesive, followed by Meths or IPA to remove any oily residue left by the WD40.

What's wrong with 6x30 RACI finders?
Ian McCallum replied to Franklin's topic in Getting Started Equipment Help and Advice
That's interesting to know, regarding LP and the size of the finder scope. I've only got the 9x50 variety. -

Stupid clouds are going to ruin the eclipse for me

This awful weather is putting me off getting more equipment.😒 -
Sky-Watcher EQ5 Deluxe - Pros and Cons...
Ian McCallum replied to Ian McCallum's topic in Discussions - Mounts
I'm not in a desperate hurry for one at the moment, so will hold off and see what comes along. Bad time of year, etc. -
Must be because I got some more astronomy related stuff, recently.🙄

Sky-Watcher EQ5 Deluxe - Pros and Cons...
Ian McCallum replied to Ian McCallum's topic in Discussions - Mounts
So basically the EQ5 would be good enough for the ScopeTech STL-80A 80mm f15 Maxi then?🤔 -
What's the advice regards dust inside the lens elements of a refractor? 🤔 I cleaned the objective lens with Baader Wonder Fluid and the Baader microfibre cloth. I used the method described below... https://www.skyatnightmagazine.com/advice/clean-a-refractor/ If the dust inside won't affect the image, my thoughts are to leave well alone.

How do you describe the end of an eyepiece?
Ian McCallum replied to bendiddley's topic in Discussions - Eyepieces
I just call it 'Fred'.🤣🥼🚪 -

This guy did a good job of replacing them, on a second hand mount that he bought. I wonder if he's a member on here?🤔 https://youtu.be/tGTY61b5HPg -

Any video or photos will just be occasionally, the vast majority of stuff will be visual. -
Sky-Watcher EQ5 Deluxe - Pros and Cons...
Ian McCallum replied to Ian McCallum's topic in Discussions - Mounts
I plan in the future to get one of the Scopetech 80mm F15 refractors from Autie @FLO, so that will be the longer OTA to go on the EQ5. No problems regarding the bolts, as I've already been forewarned in a YouTube video. I think one set is M8 and the other is M10, so no major problems.
