Thanks for that. The write-up says screw top design. Are you familiar with how that works, as in what part of it screws in where, in respect of the focussing barrel and main eyepiece?

Anyone know where I can get one, please? Seen plenty of 2, 3 and 5× Barlows advertised, but no 1.5× ones

Yes, refocussed. An update now though; I managed to use my highest power (6.5mm/153x) eyepiece on Jupiter just now as it's the first clear, windless night I've had since buying the filter. View without the filter was exceptional - 2 bands clearly visible. View with the filter and refocussed- 2 bands still clearly visible but stood out a fair bit less than without, so the total opposite of why I bought the filter in the first place. Really disappointed. PS., anyone want to buy a hardly used neodymium filter at a bargain price? Are sales even allowed on this site?

Ok, maybe my expectations were too high

Well that was a waste of 80 odd quid. Finally had the chance to try out the new neodymium filter on Jupiter tonight, but too windy for high magnification so only went to 50x Without filter: 2 bands clearly visible With filter: No bands visible, just a bright, featureless disc Gutted!

Ok, FLO are still saying 1-2 days for the contrast booster to be available - 2 days after I first read it on their site, and 1-2 weeks for the neodymium filter - nearly 4 weeks after I first read it on their site. So rather than wait for the 1-2 days or 1-2 weeks to materialise, I found a neodymium filter in stock on Harrison's Telescopes and have just ordered one

Thank you, and the review you tagged was an excellent read. It made my mind up to buy the contrast booster... but it's out of stock! It says on their site that stock is due in 1-2 days so I'll try again then

Ah, they're one of the shops I looked at that listed it as out of stock. Never noticed they were getting some in 2 weeks, so thanks for that

Damn it, all your replies have convinced me I want one of those Baader Neodymium filters but it seems to be out of stock (which usually means discontinued) in most places except Amazon, which is charging an extortionate amount over the price that shops (which are out of stock) are advertising it for

Thank you, you learn something new every day

For 'very bright objects', do you mean the Moon or the likes of Jupiter and Venus as well?

That's really strange, I've always assumed astronomy's best when done in as dark conditions as possible.

Perfect, my telescope/eyepiece combo's maximum power is 153x

Must be impossible to not get get dark adapted when observing at night, surely?

Recommendations, please, for best filters for bringing details out on Jupiter, whose brightness often overwhelms them. Also, would a filter enhance Mars's details too? I've often read about filtering Jupiter but never anything with regards to Mars Thanks

😃

Very difficult taking shots this way and took many attempts, but really pleased with this one
