    Great video, but not sure why you needed the bolts and washers under the pier, as you level it with the top plate anyway…also the pier could move on the wood that you have put on top of the concrete blocks, as the wood expands and contracts in the humid air… Great build all the same 👍🏻

    I guess leveling the pier at the bottom makes it less likely that major adjustments will be needed at the top plate very often. I just followed the recommendation from SkyShed regarding the placement of the nuts and bolts. That wood is cosmetic only. There’s a gap between the wood and the nuts underneath the metal pier. The wood just slips over the 4 bolts. But the 4 J bolts are set in concrete.

    I watched the movement of the mount very closely while slewing. I could not see any vibrations or shuddering. Grabbing a hold on the pier and mount, they are very solid and don’t budge any. I have a 1/2” gap between the floor and the concrete pier. The first session or two of imaging should reveal any issues with stability or confirm none exist - the proof will be in the guiding and image quality. Regarding SkyShed, I got the impression they are short staffed and it adds some delays. Also, they seem to process orders in batches. So the timing of your order placement in relation to their next batch seems to determine if you wait for several weeks or 2-3 months. I ended up missing a batch, thus had to wait longer to receive the pier.

    Yes I could tell in the first video at the other camera angle there was a large slope to the property. You do what you have to do. I'm sure you two will be glad to have the camper under cover. I was a little surprised, it didn't appear they had plastic around the lower walls for splatter during the pour? Maybe your concrete crew was better than the ones I have seen! Will you be able to have insulation in the roof since it is a rolling roof? I know your area gets hot in the summer and cold in the winter. I love watching the fast movement of the clouds behind the structure when the video is sped up, looks amazing.

    Unfortunately I have no view of Polaris so I can’t use SharpCap. Lately I have been using my UV IR cut filter with N.I.N.A. so I can use shorter exposure times and do the alignment earlier in the evening. I think PHD2 has a drift alignment tool but I never tried it.

    When i've tried sharpcap with ipolar i've found that they are consistent both with each other and with seconf measurements with themselves. I did a run with nina after running sharpcap, and was 6 minutes off. After adjusting to under 30 arc seconds i ran nina agsin, snd was 6 arc minutes off again. The best thing about ipolar is thet i can usually polar align about 30 minutes earlier than i can with anything else.

    Hey Mark well the EQ6 is certainly a solid reliable mount, so should help. Very surprised your ioptron is not handling above 3 mins subs, especially with something like only the Redcat on. You may want to look at posting your PHD2 log files on cloudy nights some folks might be able to help you work it out.

  • @marksastrojourney

    I’ve read several threads on there, it seems like a good forum for getting suggestions. IOptron had me send them the phd2 logs before they had me send it in for servicing. But they didn’t recommend any course of action or different settings aside from the service they did on it.

    What sort of building permits and code inspections regarding the building plans did you have to go through or did the builder take care of those issues? Amy Astro started an observatory and she had to keep resubmitting her building plans because the sliding roof design was unusual and they felt a garage door type track system wouldn’t work in windy conditions. After two episodes of her observatory build her KZread channel content ends with no updates in over a year.

  • @marksastrojourney
    @marksastrojourneyАй бұрын

    this builder is Amish and doesn’t handle the building permit process. So I did the building permit online. In our area, they prefer online submission. I had to attach my plans, which clearly indicate the observatory and the roll off roof. The building inspector gave the final inspection approval. He came for several inspections. Regarding the electric, my electrician did that permit separately. The final electrical inspection is still pending as the electric meter is getting hooked up today. I feel all roll of roofs involve some risks from storms due to the nature of their design and not being permanently attached. But I believe building standards and tolerances vary by state, city and county to a certain degree.

    What were your PHD2 RMS errors reported with your iOptron. What guide camera and main camera. Focal reducer? Focal length? I’m surprised because I have an AVX mount and if I can keep the RA and DEC under 1” I can shoot up to 5 minutes I once tried a 10 minute exposure with success. I’m using a C8 SCT with OAG at 1442mm. I thought iOptron were solid mounts. It’s on my list as a possible mount upgrade, CEM40 or GEM45. The EQ6 has a good reputation. Good luck with it. Didn’t want to go strain wave?

  • @marksastrojourney
    @marksastrojourneyАй бұрын

    I just checked the log folders for PHD2 and noticed no log is getting created because I don’t have that checkbox enabled. So I can’t check history from a recent session to give a precise statistic. However, my recollection is that for the most part the line on the graph in PHD2 stays between -2¨ and +2”. However, there are spikes out to -+4 and even -+6. I have the mounts PEC disabled and have the Predictive PEC enabled in PHD2. I found PHD2’s PEC works better than that of the mount. Also, I’ve been getting my polar alignment down to under 1 arc minute. Usually, I’m able to get that down to around 20 arc seconds on both alt/az. Guide camera is a ZWO 120mm mini guide camera. Main camera is a ZWO ASI2600MM Pro. Telescope is a WO Redcat61 with focal length of 300 and f4.9. No focal reducer involved with this scope. I have seen many positive reviews of the CEM40 and GEM45. But I’ve found several people’s threads facing similar guiding issues as mine with the GEM28. Unfortunately, I didn’t find those threads until after I had it a while. In no way am I trying to cast a negative light on iOptron. As long as I stick with 3 minute or less exposures, the mount does well. It is also quite portable and I’ve taken it on multiple trips to other sites//states. I did multiple attempts at 5 minute exposures and just got tired of discarding so many bad subframes. I can still get decent results at 3 minutes even with narrowband. That being said, I’d still like to do 5 minute exposures. As a side note, I did send my GEM28 back to iOptron early on to have them service it. This resulted from a series of support communications. They replaced a drive belt, replaced the grease in the gearbox and adjusted it and said it was fine. Regarding strain wave or harmonic, I guess I might try that in the future for a grab n go mount. But in this case, I’m going to put this EQ6-R Pro on a pier. I don’t plan to be swapping out mounts on the pier or using this at other sites. Thus as a personal preference I like this mount for this use case. For now if I travel, I’ll take the GEM28. Thanks for the interest and watching - clear skies!

    The electricity to the building situation has me a little stumped. It's been almost 2 weeks since the inspector gave the go ahead for REMC to connect the meter/line. I called them to ask when it might be done. They said, it's not on the schedule yet and sent me to the voicemail of one of their engineers. But no call was returned to my message. I thought they'd be eager to hookup anything that would start making them money. I guess they don't have enough workers or they sent them all out of state to work on storm damage repair and have nobody to do local work. I doubt they'd be here more than 30-60 minutes. The line is already installed and just needs to be connected on both ends.

    I’m in the southern hemisphere (Sydney, AU) and mobile (and mostly image within a 40 min drive from the centre of the city so around SQM 19.9 to 21). Setting up each time, you want something simple and fast. I like the PoleMaster camera as it just clicks into place on the mount’s body, in the centre of the RA rotational axis and you don’t have to worry about focusing. The polemaster app is a pain so don’t use it. I use sharpcap polar alignment routine with the Polemaster camera. All this can be done just when stars appear. The setting up NINA, main camera, focus etc is all done next after polar alignment is finished. I think it would be interesting to use a drift alignment method (as you suggested) and compare others to that. I’ve been told an app such as PemPro would speed that up.

  • @marksastrojourney

    thanks for sharing your observations! I also think if the mount is on a tripod instead of a pier, one of the tripod legs can shift ever so slightly and throw it off after it’s polar aligned. The equipment cools and warms over time and it seems like that’s a factor as well. Clear skies!

    I've been doing polar alignment for almost 4 years, and iPolar is BY FAR the best. <1 arcmin polar alignment error in <1 min of real time. By the way, that circle is not supposed to be blinking. If you are doing your polar alignment when it's not exactly dark, maybe try increasing your iPolar exposure time to 750ms for better SNR (unless it's so bright that it would saturate the pixels.) Another tip: for those with adapters and not a built-in iPolar from the factory, I do 5 calibrations back to back, then average the x,y center positions and enter the averages manually in settings. That calibration will be super precise and lasts for at least a year.

    @alanjs1 That sounds like a good setup!

    Good thing that nina and sharpcap were saying roughly the same deviation. this is reassuring. I have recently re calibrated my ipolar (changed the x-y values) after I performed a drift alignement . The circle and cross were close but not right on. I am planning to compare also with nina and that similar routine in APT. Let's keep in mind here that PHD will give the polar error of the guide scope , which may not be perpendicular to the mount's axis. Thanks for the video.

    I do 5 calibrations back to back, then average x,y positions of the center of rotation and enter those averages in settings. This way, the polar alignment is as good as it could be with respect to the hardware limitations.

    Many possible issues here. First, the ipolar must be perfectly installed, flush against the mount with no tilt for best results. Second, try nina and sharpcap thru the ipolar. Using the scope to polar align setups up possible cone error unless the scope is properly pointing straight using adjusting rings instead of the clamshell clamps. Personally I use ipolar but a good possible test of your alignment is to leave ipolar open on green after your alignment. Then slew 90 degrees east and then west to see if the alignment stays green, or close enough, thru the entire slews. Thanks for the tests.

    Thanks for sharing some ideas! The polar scope came installed from the factory and I never have assessed whether or not it might not be installed properly. But it does appear to be fully flush to the mount as you mentioned. Interesting suggestion regarding slewing. Clear skies!

    maybe you could test with the PHD2 guiding see which method is the best

    That 5mm looks a lot like the old tmb burgess planetary series, which has been sold under many brand names. The 25 is just a fancy dressed up plossl like the vixen NPL line, and all in fact are made by the same company, synta. This scope is also available for more money as a vixen 100ed, and of course the orion 100ed. When these first came out, the 5mm had the same looking cosmetics as the 25. It was a longer eye relief than 5mm plossl, but I don't think it was as nice or as wide angle as the one you just got. Those are actually pretty decent. It would be nice if more scopes came with those instead of the usual small plossls or MAs for the high power. Also.note that the twist up eyeguards don't Indicate what the eye relief of the eyepiece actually is, nor does it adjust the eye relief. Buy yes it does get the eyecup out of the way for eyeglasses, but more importantly you can keep them all the way up to minimize the chance of other people getting eyelash grease or mascara on your eyepieces. Scopes like that usually destroy the common, sometimes slightly out of collimation SCTs and Dobs that many astronomy club members bring to outreach events, on planets, which is the most common outreach target other than showpiece dsos on the larger aperture scopes. And the views of open clusters are best in refractors, even in light pollution. I'm sure you love it by now

    thanks for all the great details shared in your comments! I do still enjoy this telescope. I’ve since added a wo redcat61 for wide field imaging. So now I end up using one for a month or two and then switching to the other one. I have to admit, since I’ve learned more of the basics of astrophotography I’ve barely done any visual astronomy. Clear skies!
