Several of us (Jay, Jeff, Jorge, Mark, my 2 young daughters and I) made it out to Pit-N-Pole for an observing session last Saturday evening. It was a bittersweet time. Sweet because the skies were really clear and steady. Bitter because frost started settling by around 7:00 pm. That seems really early for frost like we got, but that's what happened. Of course it did not get any better after that. The frostiness continued but I was able to use my newly acquired 12V hair dryer to heat my eyepiece to the point that it would not fog over as soon as my eye was close to it. Each heating session would last for about 30 minutes or so then I would have to apply more heat. Anyone considering this option to dew management should know that it worked well for me and it is hard to beat the $15.00 price tag. You have to be able to power it with something that has a cigarette lighter power connection. I use my jump starter battery. If your car is close, you can use the cigarette lighter or any similar accessory power connection. If you are considering dew busting devices, feel free to use my hair dryer anytime we are observing together. Just don't try to dry your hair, as there is very little heat and air that comes from that dryer. I don't think it would work well for a SCT type telescope as the corrector plate is just too large to heat with the dryer. But again, try mine out, then you'll know. Anyway, back to the observing session, we called it a night after 11:00 or so. We had good times enjoying the night skies, but the frost got to us early. As usual for this hobby, observing the night sky is only part of the enjoyment, good conversation with like minded people makes the evening a good time. Mark's heater made it a great time, especially for my daughters! Keep looking up!

I haven't been to Pit-N-Pole for several years but since it is near the local valley floor it is particularly susceptible to frost and dew. I was out observing in Sandy and no frost appeared all night long but the skies were light polluted. The weather forecast said the dew point was 13 deg. F. I suspect the dew point was much higher at Pit-N-Pole or did it get that cold. -----Original Message----- From: utah-astronomy-bounces@mailman.xmission.com [mailto:utah-astronomy-bounces@mailman.xmission.com] On Behalf Of Hutchings, Mat (H USA) Sent: Monday, November 28, 2011 4:56 PM To: Utah Astronomy Subject: [Utah-astronomy] Saturday observing report Several of us (Jay, Jeff, Jorge, Mark, my 2 young daughters and I) made it out to Pit-N-Pole for an observing session last Saturday evening.

If you do not have some sort of eyepiece heater, a great way to avoid frost is one of those disposable hand warmers. You activate it, and rubber band it to the eyepiece. It works like a charm. As Don says, pit n pole is especially prone to frost, but one handwarmer will keep your eyepieces clear for about 6 or 7 hours. Depending on the scope design, sometimes it can just be mounted on the eyepiece holder or the focuser, otherwise you need to switch it with the eyepieces. Quoting "Don J. Colton" <djcolton@piol.com>:

Jo, Your tip is a good one and works well. I should have thought of that as I got two boxes of hand warmers from San's for about $10 each. The temp if I remember right got down to about 10 degrees or 9 degrees F so yes, the dew out there went up to 90% and was thus frost. Lakeside had higher temps in the low 30's with only about 60% to 65% humidity. I think unless I am heading out for a quick session I am heading to Lakeside unless I have my dew heating stuff with me. I forgot it that night. On Mon, Nov 28, 2011 at 5:58 PM, Josephine Grahn <bsi@xmission.com> wrote:

It isn't necessary for the air temperature to be below the dew point. All that is required is for the equipment to be below the dew point. It is not uncommon for equipment out at night to cool below the air temperature by radiation into the nearly absolute zero emptyness of space. When the equipment cools down below the dew point then frost forms on the equipment. ________________________________ From: "Hutchings, Mat (H USA)" <mat.hutchings@siemens.com> To: Utah Astronomy <utah-astronomy@mailman.xmission.com> Sent: Tuesday, November 29, 2011 8:43 AM Subject: Re: [Utah-astronomy] Saturday observing report The dew point was higher, but it did eventually get about that cold.

I've tried making that point, good luck. The equipment need not be "warm" to the touch, just warmer than the dew point.
"It is not uncommorn for equipment out at night to cool below the air temperature by radiation into the nearly absolute zero emptyness of space." Brent, If I didn't know that you sold your 22", I'd say you'd been stargazing from atop the 20th step of your ladder to reach the 'nearly absolute zero emptyness of space'. Bernson used to tell a tale about you having people at SPOC look 'with both eyes' at the first quarter moon with the 22" unobstructed/unfiltered while on the same said ladder years ago.

Joe, Certainly the 12" corrector plate is too big to easily remove frost with the 12V hair dryer. But if you use the dryer to add heat now and again to keep the corrector plate above the dew point, then it might work okay to prevent frost from forming in the first place. But as I said in my original post, anyone is welcome to try mine out when we observe together and then you'll know for sure if it works for your equipment. The dew cap that is in the works for you is also a necessary part of dew avoidance.

Sigh. Thanks, Joe ________________________________ From: "Hutchings, Mat (H USA)" <mat.hutchings@siemens.com> To: Utah Astronomy <utah-astronomy@mailman.xmission.com> Sent: Monday, November 28, 2011 4:56 PM Subject: [Utah-astronomy] Saturday observing report Several of us (Jay, Jeff, Jorge, Mark, my 2 young daughters and I) made it out to Pit-N-Pole for an observing session last Saturday evening. It was a bittersweet time. Sweet because the skies were really clear and steady. Bitter because frost started settling by around 7:00 pm. That seems really early for frost like we got, but that's what happened. Of course it did not get any better after that. The frostiness continued but I was able to use my newly acquired 12V hair dryer to heat my eyepiece to the point that it would not fog over as soon as my eye was close to it. Each heating session would last for about 30 minutes or so then I would have to apply more heat. Anyone considering this option to dew management should know that it worked well for me and it is hard to beat the $15.00 price tag. You have to be able to power it with something that has a cigarette lighter power connection. I use my jump starter battery. If your car is close, you can use the cigarette lighter or any similar accessory power connection. If you are considering dew busting devices, feel free to use my hair dryer anytime we are observing together. Just don't try to dry your hair, as there is very little heat and air that comes from that dryer. I don't think it would work well for a SCT type telescope as the corrector plate is just too large to heat with the dryer. But again, try mine out, then you'll know. Anyway, back to the observing session, we called it a night after 11:00 or so. We had good times enjoying the night skies, but the frost got to us early. As usual for this hobby, observing the night sky is only part of the enjoyment, good conversation with like minded people makes the evening a good time. Mark's heater made it a great time, especially for my daughters! Keep looking up!

Thanks, Mat! I'm excited to extend my observing season. -- Joe ________________________________ From: "Hutchings, Mat (H USA)" <mat.hutchings@siemens.com> To: Utah Astronomy <utah-astronomy@mailman.xmission.com> Sent: Tuesday, November 29, 2011 12:48 PM Subject: Re: [Utah-astronomy] Saturday observing report Joe, Certainly the 12" corrector plate is too big to easily remove frost with the 12V hair dryer. But if you use the dryer to add heat now and again to keep the corrector plate above the dew point, then it might work okay to prevent frost from forming in the first place. But as I said in my original post, anyone is welcome to try mine out when we observe together and then you'll know for sure if it works for your equipment. The dew cap that is in the works for you is also a necessary part of dew avoidance.

Joe, after you get your dewcap, you'll be in the market for a polar suit before the frost signals go-home time. Dave and Brent, get thee to a pied-à-terre. ;-) _______________________________________________ Utah-Astronomy mailing list Utah-Astronomy@mailman.xmission.com http://mailman.xmission.com/cgi-bin/mailman/listinfo/utah-astronomy Visit the Photo Gallery: http://www.slas.us/gallery2/main.php
