Cell phone astrophotography - beginners attempt

 

I posted by my work to Instagram?
?
iPhone 12
Lumilapse Bluetooth shutter control?
Native camera app set to Max night mode?
30 second intervals stacked and rendered using Star Tracker app.
?
Time sequence is about 9 PM to 6:30 AM ?April 27-28.
?
next step is seeing if I can bulk apply contrast and brightness settings to the video or the ~900+ images before beginning the process.

I¡¯m heading to Salt Meadow Park in Madison tonight to help someone understand their telescope. Looks clear but breezy so not sure how long I¡¯ll make it.

Re: For Those Who Want Free SW for Image Processing

 

¿ªÔÆÌåÓý

I *just* started using SIRIL.? I use Deep Sky Stacker (free also) for pre-processing images.? Last week I dedicated our one clear night to imaging the M-63 galaxy.? When I went to use DSS I discovered that over half the images were unviewable/random color! noise.? I tried using the the GIMP (free photoshop kinda like) and it showed the images being ok... but I wasn't positive as older versions of GIMP show FITS files in three color bands RGB and the latest one showed just one image.? So I went looking for a Fits viewer and stumbled on SIRIL.? As with most software, it has a bit of a learning curve, but I've been able to process my first 90 images and the results are great.? Next up I will do all the images.? Now, mind, I don't know why DSS shows corrupted files while SIRIL doesn't, I'm just saying that perhaps I've discovered a bug in DSS.? DSS is so easy to use whilst SIRIL takes some learning, and SIRIL REQUIRES biases, darks,flats, and lights - DSS does not.

Oh, and on a similar topic... if you have a ZWO ASI294MM Pro cooled camera (this applies to others like the B&W models) be aware that images less than 3 seconds are basically useless.? HUGE amount of noise.? I've noticed that I cannot use biases in preprocessing because I end up with unusable processed images.? I just learned this about the 294.? So - to remedy it, it is recommended to use 3 sec dark flats instead of biases.? I tried folding my white t-shirt in half (4 layers) and even in relatively dim light I could only achieve 1 sec images with the correct histogram.? So I'm making an LED "light" box that I should be able to get 3 second exposures using.

Also regarding the 294 - supposedly there is a software update that quadruples it's resolution - ie files go from 11M to 49M in size.? I haven't chased it down yet... I've got to get my light box done first.

Cheers!

April Meeting Minutes

 

¿ªÔÆÌåÓý

Sorry for the delay in getting the minutes out.?

We had family in Vermont the weekend after the meeting (Easter for those who celebrate) and we got distracted with teaching grandson Wilder (3) to ski. ??

NOTE: TAAS has committed to having a table at Catherine Kolnaski STEAM night THIS Tuesday, April 29, from 5-7 p.m. They would love us to have a solar scope there,if anyone is available to provide guidance for observing.? Mark and I will staff the TAAS table inside. The TAAS table plan is to have a small telescope, the Seestar, and membership applications. I am also going to try and find a fun Night Sky Network activity to have available, also.?

MINUTES BELOW!?

TAAS Monthly Meeting Minutes

April 17, 2025

?Present: Mark S., Deb F., Lee P., George B., Alan S., John S., Gerry K., Leslie B., (RM) Max, Jeff D., Brian R., Jerry?T.
?Mark attended the ASGH meeting on Wednesday night via Zoom, and he enjoyed the meeting and the presentation on the new planetarium in Stamford.
?Mark asked if everyone had reviewed the agenda. Lee remarked he added an agenda item regarding Shoreline¡¯s May 17 event. It is a town sponsored event. Jeff will share more information when he gets the official flyer. No dogs are allowed. 8:30-10:30 p.m.
?Mark called the meeting to order. He reminded everyone of the agenda he had sent previously. The last item on the March agenda was a discussion about club growth based on an article Mark had read in Reflector Magazine. The discussion in March was cut short due to lack of time so Mark put this as the first agenda item for the April meeting. ?
The three primary methods of growing your club were:

¡¤? ? ? Outreach

¡¤?????? Social Media

¡¤?????? Leadership turnover

Mark felt we were doing well with outreach. Lee mentioned he thinks we do a lot with young people at the schools, Hammonassett, and Avery Point. He felt those events reach young people, tourists, and the college students. He was wondering if there were other things we can do to attract adults, who are more likely to become members. He suggested library events. Mark and Leslie mentioned TAAS does two or three events a year at the Waterford Library. Lee wondered about putting more posters/flyers in schools and libraries.
Leslie mentioned the East Lyme high school planetarium (supported by the Stars to STEM organization) is planning to do beginner level astronomy programs once a month on the last Saturday of the month, starting April 26 from 7-9 pm. Leslie would love to have TAAS support these programs. The first Friday of each month they are doing laser light shows with live music.
?Mark asked for a motion to go forward with getting brochures and flyers for the libraries and other public locations. These would include membership forms.? Max-motion/four seconds.
?John brought up having a tri-fold brochure with one-fold being the membership. Deb commented we already have a brochure with one-fold being the membership application. Deb emailed a pdf of the brochure to everyone and asked for suggestions of any changes to make as we are almost out and will need to make more copies.
?John suggested that the groups.io is going to reach capacity. Leslie suggested that if people have not been active in a year, perhaps they?should be removed.
?George suggested that although lots of people may want to look through our telescopes, the number who will join, get a telescope, frequently check the Clear Sky clock, observe with the group, and go to NEAF is rather small.
?
John asked if George could include a membership application when people email him with questions. George will do so.
?Jeff chimed in about how SAS has grown their club from 8 to 32 members in a year and a half. They also gained their 501(c)3 status. They have club telescopes, are active on social media for anyone who wants to learn more. Social media is also their advertising and marketing. They save their groups.io for members and club dynamics. They recently rolled out a PayPal on-line membership.
?Jeff suggested Mark¡¯s intention with this discussion is to try to poll the club members to determine what members of the club want to see for the future of TAAS.
?Mark said we have covered outreach, and moved into social media (FB, website, Night Sky Network). Mark asked if we should spend more effort promoting the club on Facebook. Also, the website needs a refresh. It is a great start that Lee built, based on what we wanted 2 (?) years ago. Leslie suggested we need to add some fresh content; maybe more members astrophotos. Discussed that we also have a lot of unused material from the Night Sky Network.
This brought us to the final method for growing the club, which is leadership turnover. Deb added that we should choose a meeting time when we take nominations for our leadership so that we can be self-sustaining for the future.


Other Items

Leslie provided a Conn College Observatory update. They are hoping for a TAAS day in May. Lots of equipment is here but the equipment is not yet installed.


Deb reported in as the Night Sky Network Coordinator. Deb reported on 29 outreach events in 2024 to the Night Sky Network (five are required to maintain our membership). Deb has started entering our 2025 events. She has more past and upcoming events to enter and then will be reporting on all of them. As we have many more events than five scheduled for 2025 we will have no trouble meeting our five required events so we will continue to benefit from our Night Sky Network and continue to get more of their very cool materials for outreach. She hopes to have all currently scheduled 2025 events entered and any that have already taken place reported on by the May meeting, now that she has once again retired from her seasonal full-time Snowsports job.

?George reported on our finances in his role as the treasurer. Finances are the same as last month. We have twenty-five paid members.
?Upcoming calendar events
Tuesday, April 22-Sturm Lecture at Wesleyan (see flyer from John S) 8:00 p.m.

Thursday, April 24-Hamden Library

Hubble Telescope Anniversary & Solar Observing ?3-5 PM (Some ??????libraries got ? solar scopes from a CT Library Repository)

Friday, April 25- Lyme Land Trust 8 PM (postponed to Sunday, the 27th)
Friday, April 25-26 Messier Marathon at Propbusters in Salem (postponed due to weather)
Tuesday, April 29 Groton STEAM Day Catherine Kolnaski School 5-7 pm
Saturday, May 17 Shoreline Star Party ? (Jeff is awaiting approval from the town for these events)
East Lyme Planetarium shows (see link! There are lots!) ?
https://www.starstostem.org/programsevery Saturday April 26 through May 17
?NEAF discussions were held for the remainder of the meeting.? Members who attended and made purchases apologized for the upcoming clouds.
Leslie got SkyWatcher Wave 100i mount and Stellervue 90 APO Raptor Carbon Fiber.
John S. was busy working the booth while encouraging others to buy things. He succumbed to another Ha solar filter.
Jerry bought a 2X TV Powermate.
Lee got the new ZWO field rotator(?)

I had good conditions for imaging. Imaged the Whale Galaxy and M101. Looking to see what I get tonight before I process.

Wow George! Great work.?

We observed on Sunday with Mark¡¯s son , Michael. Here¡¯s my recent Seestar jpg¡¯s.?

Last night it was clear here. We did some short naked eye observing so we were with you in spirit. But I was tired from a day of skiing g and Mark from working g on the race car so we went to bed. Looking to try a Messier Marathon Sunday night in Salem.?

Weekday Observing

 

As expected, the conditions last night were poor. Seeing was bad as was the transparency here in Quaker Hill. However, I took the time to set up and felt obligated to look at what was not hidden by trees. I grabbed about 25 Messier objects, a few NGCs as well as Mars and Jupiter over a two hour period. Tonight looks similar, but I¡¯ll wait until dark to decide whether to bring the stuff in or give it another go.
