Problems Focusing on Infinity with K-70

The problem is that the lenses wonít get to infinity; just a tad short. I prefer
If they get past infinity so I could focus back to infinity. I never use AF in astrophotography and I do use iOptronís Sky Guider Pro mount. The focusing device (Bahtinov mast) is intriguing. Will explore.,

Is at times a problem, especially when I'm out in the field using the K-70 for Astrophotography. It's maddening, actually.

Am I doing something wrong? I Mainly use a Sigma DG 70-300mm lens, but also have a Rokinon 1:2.8 14mm and Pentax 18-135.

Advice both needed and appreciated.

Thank you for your kind words (and little joke about acne) about my Six day moon photo. Knowing the work and learning I put into that photo, Iím pleased that it turned out well.

Keep shooting!

Thank you everyone for your help. Searched the forums for this topic but haven't found a thread on recommendations for light pollution suppressors, or LPS.


Does anyone use LPS filters when shooting the night sky?

Many thanks. I feel a bit embarrassed. Do you know of a good live view magnifier that will fit the k-70 LCD screen? Thanks again.

Thank you for helping me stumble to the answer. Regarding Live View, is there a live view magnifier that you'd recommend? Don't want to spend a lot of money.

I like your photos, UNP. Where in Carbondale did you shoot these photos? I have a few in this thread, and you can see where in Carbondale I shot mine. Your Bailey's Beads photo isn't a beads photo in the classic sense, but it's close. That's Probably because of the milky goop we were shooting through that day. Anyway, well done!

Thank you for running the contest Adam. Everyone seemed to shoot something that they can point to with pride for the rest of their lives.

I've included some signage near the Denny's Restaurant in Carbondale, the place I choose to shoot from after I rolled into town at 3 a.m. on E-Day.

I blogged about my E-Day experiences. If interested, you can find it here: Chasing the Shadow in Carbondale

Thank you and congrats to everyone's fine photographs in a once-in-every-seven years event. See you in 2024!


Found and added couple of my photos that revealed Regulus. It appears at the 9 p.m. position next to the face of the sun/moon combination. Regulus is four-star system, almost 80 light years from us and shines at a magnitude 1.36. The so-called "heart of the lion," Regulus is the brightest star in the constellation of Leo the Lion. In the northern hemisphere, Leo rises is an early spring constellation. When we see Regulus rising in the northeast in the early evening, we know that we've seen the best that winter can dish out and spring is coming quick.

You're missing my point Pentax people, or perhaps I didn't explain it correctly. When my camera is in Manual mode, I can no longer get the shutter speed in fractions of a second, like 1/125. It turns out that I'm getting seconds of exposure. What happened? I tried moving the E-meter; all it did was increase the length (in seconds) or my exposure. Any ideas? I'm desperate to find the answer. Thank you.

Astronomy suggestions with the K-70?

Hi Astro Dave,

Am new to the K-70. Going to use the U1 bracket to preset the partial eclipse shots. What focal length, ISO and shutter speed do you recommend for partial eclipse shots? I plan to also use mirror lock, cable release and a center weight on my tripod to keep the camera as quiet as possible. Will either be shooting in Illinois or Nebraska, whichever has the better weather forecast on Aug. 19.

Many thanks for your recommendations.

The focal length setting is correct, but the exposure settings has devolved from 1/60, 1/125, 1/200 etc. to 1.6", 2.5", etc.

I have no idea what decimal exposure settings reading mean, I'd like to return to the traditional shutter speed settings we all know and love.

How do I restore the preferred exposure setting readings that are fractional, like 1/125?

Bracketing using U1 and U2 functions

Thank you Stevebrot for ending a three-day search for a solution that is not possible.

It looks as if I'll have to settle for mirror-lock shooting during the solar eclipse; it's the best bet to get the best pictures.

Many thanks to you and others for your/their expertise.

Bracketing using U1 and U2 functions
Posted By Roger Dier

Views: 1,525
Are you able to set up and use the desired bracketing outside the custom U1 and U2 modes?

Yes, I was able to use bracketing outside of U1 and U2 modes, and I was able to use mirror lock when in U1 and U2 modes, but I have been unable to use them together in U1 and U2. I'm using a remote (cord) to release the shutter on mirror lock pictures. However, I can't figure out how to program mirror lock AND bracketing in U1 and U2 and be able to use a handheld switch to take the mirror lock pictures.

What exposure mode, ISO, and bracket settings are you wanting to use?
In U1 (partial eclipse) F10, ISO 100 and SS of 160 to 200, or something in-between.

How is this not working for you?

It's maddening. I've been trying to figure this out off and on for a couple of days. The basic question remains: Can I bracket photos using mirror lock in the U1, U2 and U3 modes, using a shutter release cord.

I very much thank you for your help to date. Everyone.
