PM me if you have questions about the A star 400 f 2.8 , it could take many posts to answer every question you will have! Haha!
Actually I lucked out and upon opening it's case I found that the original instructions were still in the little compartment. I sat and read through them and dorked around with the lens some last night to get the hang of things. This is a very different monster than anything else I have in my possession. As an example the ability to preset focus threw me for a loop. Apart from being rather filthy it was in good working order but didn't have any of the drop in filters. I put the red intensifier I got for it in once I cleaned the dust out of the back of it, there was a lot probably because the rear cap fell off in transit. A good blowing out, front element cleaning, and body wipe down did wonders and it is in better shape than claimed as most of the marks on the body from wear were actually dirt smudges. Now if it would just stop raining.

I guess my first real question is do I have to have a filter in it for it to focus correctly or can I get by without one? I did go and get a good UV filter to put in just to keep the dirt and dust out but if I don't need want a filter in can I take it out?

The short answer is YES.

The 400 with my K3-II I can use or not use the drop in filter, just a slight re-focus if you take a. picture then remove/ install the filter. With the AF 1.7 just a half press and it is in focus. On a full frame camera there may be issues that I have not seen with the K3-II. In the past using film cameras I never shot without the drop in filter in. That was the law!!!!! I have a Pentax skylight and Pentax UV filters for the drop in, normally the UV is installed, mainly to keep dust from getting deeper into the lens! To date the lens has never needed service or internal cleaning. Use the focus preset with care as the focus is very smooth but very strong and I worry about possible internal damage if you fast focus and hit the focus stop hard. As the drop in is 49mm, you should have no problems finding any filter you need for Astro... The front filter is 145mm X 1.5mm thread if you are wondering, it's easier to find the Lost Dutchman mine.....which no one has ever found....than to find the screw in front filter...If one came with your lens, treasure it! Haha....

I don't think I'm going to ever be using the prefocus since most of the time I will probably pointing this thing up at infinity with a very fine focus done. That was just a feature I hadn't ever seen or knew existed. It is nice that should I want to take the drop in filter out for those rare times when I won't need the red intensifier, poor man's light pollution filter, when I find a real dark spot well away from the glow of cities. I am planning on leaving that or the UV filter in it the rest of the time just to keep the dust out though. The drop in filter being 49mm is actually really nice as those filters are inexpensive easy to find.

Thanks for the answer. I might be able to make it out tonight so hopefully saturday I can start posting some pictures from the lens.

The Principality of Sealand, commonly known as Sealand, is a micronation that claims Roughs Tower, an offshore platform in the North Sea approximately 12 kilometres off the coast of Suffolk. as its territory.





This will give you an idea of the distance.

I wonder how many countries have recognised it? ;-)

I see that Sealand will bestow titles such as baronies, knighthoods and duchies. One can become a Duke for only $US734.99: Products | Principality of Sealand

I'm going to see if I can get a boat trip out to it, so I can get a closer look

CAREFUL! They might send out their navy to intercept you. Do you have a Sealand Visa?, A green card? Have you made reservations for a place to stay during your visit? Deck space for your sleeping bag is available at reasonable rates, extra charge if you bring a self-supporting tent (pegs to anchor a tent are against federal Sealand law). Make sure to register at your embassy when you arrive. etc, etc. etc.

That's a masterly capture. I know all too well, from numerous discarded chromes (back when) and image files how difficult it can be to trip the shutter at the right moment on one of those big dragonflies in flight. They can go out of the FOV before you realize they're in it.

That just may be the best dragonfly photo I've ever seen. Not only is it in flight and sharp, but you used a slow enough shutter speed to allow some of the wing motion to show through. I'll second @WPRESTO 's use of the word "masterly".
