Lidl have got their battery chargers in from tomorrow - https://www.lidl.co.uk/en/Non-Food-Offers.htm?articleId=6216
Hopefully it'll be of use to somebody for charging powertanks/jumpstarters/leisure batteries.

Hi again
I just looked through my jewellers loupe and found the K in a circle right after 'JAPAN', It's difficult to make out in the pic but easier with the loupe!!
The one on fleabay looks superb!!I have some lens cleaning fluid although i'm unsure who made it, It usually works really well on my binoculars and specs!
Cheers, JohnIn your pics the circle K is also on the front of the lens cell after the D=76.2mm F=1250mm - no loup required!

The QHY also has some (in my opinion) ugly diffraction patterns from its microlenses, that shows up when imaging bright stars
I'd seen that, but the ASI1600mm seems to suffer from the same thing. There are some examples in the ASI1600mm thread:

Which camera are you hoping to get?
Probably the ASI1600mm-cool. People seem to be getting good results with it and it's substantially cheaper than CCDs with a similar chip size. The QHY163 also looks good, but I haven't been able to find any info on whether it's ok with 1.25" filters - which I've already bought. Part of the reason for this experiment was to get used to what seems to be the ASI1600 way of imaging - lots of short, high gain, subs.

There's a lot more potential to be had - there was something iffy going on with my calibration frames. PI was complaining about no correlation between the darks and lights (or something to that effect) and the final "calibrated" images are still a mess, apart from the crab Ha, which was quite clean considering it was only 15 mins of data.

I bought myself a filter wheel and LRGB filter set in anticipation of being able to afford a dedicated cooled mono camera, but in the meantime I thought I'd try using my guide camera for imaging. This was my first attempt at mono imaging (and subsequent processing) and my first time using SGPro, so it was more of an experiment than a serious attempt! The visibility was also quite poor - 4 miles and red according to ClearOutside - and the sky was bright orange.

Seben 6x30 RA finder
in Getting Started Equipment Help and Advice
Posted
I bought the finder you're talking about recently and it's terrible. If you've got a standard Synta 6x30 finder then you can unscrew the objective cell and replace the one on the Seben. The threads aren't quite right, but it seems to work. Image quality is far better than the stock Seben and you get the benefit of RACI, but personally I'd save your pennies for a "proper" RACI finder.
