Naked eye Sunspot visible with Eclipse glasses
JAC51 replied to Pete Presland's topic in Celestial Events Heads Up

Our house insurance is with Swindon and covers the observatory and contents. The only stipulation was that the observatory had to have a mortice lock. At the time I was looking I was also told that the NFU mutual would also insure an observatory as being the farmers mutual they deal with things on outbuildings all the time. Don’t work for either of the above.

APM TMB LZOS 130 F/9.2 Triplet Refractor Review
JAC51 replied to DirkSteele's topic in Member Equipment Reviews
https://www.astrotreff.de/forum/index.php?thread/95328-vier-apos-von-apm-lzos-vor-dem-interferometer/ The above link is to a 2009 article on a German site where a APM LZOS 130 F9 and a 115 F7 where tested over 9 different wavelengths, with repeats to show their polychromatic strehl I used the translate option on my browser to read it. -
APM TMB LZOS 130 F/9.2 Triplet Refractor Review
JAC51 replied to DirkSteele's topic in Member Equipment Reviews
Thank you for a very enjoyable well written review. I actually can add to your single digit figures as I have a 2005 model though I am not the original owner. Only thing I can add is to confirm your suspicion of counting craterlets in Plato the most I have seen is 6 though I cannot claim to resolve them merely see the smaller as “albedo?” features. John -
Brilliant and beautiful

Thank you for the above replies. I almost bought a TRex some 12 years ago, passing on that was a mistake. Now it looks like the AZ100 is indeed the modern equivalent needed for higher power use. I will have soldier on with my Losmandy GM8 which does a respectable job for visual x300+ though I did haven’t ditch the tripod and put it on a pier.

Happy birthday indeed I have really enjoyed your reviews and observing reports. Experienced 180mm apo envy. But I least I can share with you having a 130mm TMB F9.2 which is a wonderful telescope. Can I take here the chance to ask what mounts you are using this on for visual work. John

Really really nice individual drawings but it is the development of the Sun spots with time I find most impressive. Great observations.

Europa peaking out from behind Jupiter early this morning or late last night depending on your point of view. Telescope was a TMB 130 f9 with a Baader maxbright diagonal. Eyepieces Brandon 12mm with x1.5 Magic Dakin Barlow, 8mm Brandon with x1.25 MDB and then newish to me a 6.5 mm Morpheus. I can’t get over observing at night wearing shorts, about 20C here.

Finally! After 8-9 weeks. 140mm Frac - 20/21 July 2023
JAC51 replied to Captain Scarlet's topic in Observing - Reports
👍Great report and very enjoyable to read. I can feel the clouds and the wind, the cloud part of which there have been plenty of here in East England. My observations have mainly been confined to white light solar for the past month now. Remaining hopeful for clear skys -
Congratulations on the 10mm BCO I was given one by someone who did not like it. I found it to be a really good eyepiece and still amazing value for money. Contrast is very close to the Brandon’s I have but at a fraction of the cost. Let us know how you get on with Both your eyepieces

Astro-Physics 110mm f6 StarFire GTX
JAC51 replied to cfinn's topic in Discussions - Scopes / Whole setups
Congratulations and what struck me is how beefy the draw tube on the focuser looks compared to the main tube, almost the same diameter, it makes your 2" maxbright diagonal look like a little 1.25" one on the back. -
Imagine how long you would have to wait on Venus for clouds to clear it’s bad enough here at times.

I have already tested it out , white light solar with Tak FS60. Not the intended primary use but already very impressed. I have no intention of getting anymore . But I side that after the 17.5mm and then again after the 9mm so who knows?

Poll: GOTO / Push To or Find it yourself ?
JAC51 replied to John's topic in Discussions - Scopes / Whole setups
Starsense? Goto? I’ve only just mastered setting circles and porter slip rings on my digital Losmandy for the 5” refractor. For the little Tak star hopping and wide field eyepieces to start with at least. -

Can’t fault FLO for their packing. Or their speed of dispatch. Just ordered a pair of lens caps for one of my TAK LE’s and a pair of Baader filter draws. Here before I can even tell the wife I’ve ordered them. That conversation is about to happen. And no chance of these breaking.

Yet another Mars animated gif (24/12/2022)
JAC51 replied to NenoVento's topic in Imaging - Planetary
Great animation can you tell us roughly what time it starts and end? I was trying to sketch Mars last night at 21:00 to 22:00 UT and I was hoping to match up your animation with what I was seeing. -
I really like the effect you have achieved the colour palette is really interesting.
